Fig. 43 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 43. Occlusal morphology of the left first maxillary molar (M1) of Neacomys species. Left to right: N. tenuipes (USNM 499555), N. guianae (CM 76849), N. dubosti (USNM 461580), and N. paracou (USNM 461609).
Fig. 45 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 45. Morphology of the occipital region in Nectomys palmipes (A, AMNH 4658 [holotype]) and N. melanius (B, MNHN 1981.1296). In N. palmipes, the interparietal (ip) is deep (anteroposterior dimension) relative to its width (transverse dimension), and the exoccipital (exo) occupies most of the dorsolateral surface of the occiput. By contrast, the interparietal of N. melanius is relatively much wider than deep, and the dorsolateral exposure of the exoccipital is correspondingly reduced.
Fig. 58 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 58. Tangled lianas in the understory of swampy primary forest at Paracou, capture site for Oecomys auyantepui (trapped 1.2 m above the ground, white arrow) and a typical substrate for other arboreal small mammals that occasionally descend to near ground level (e.g., Micoureus demerarae and Oecomys rutilus).
Fig. 49 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 49. Occlusal views of upper (A, B) and lower (C, D) molars of Neusticomys venezuelae (A, C [AMNH 69907, holotype]) and N. oyapocki (B, D [AMNH 267597]). Absence of upper and lower third molars conspicuously distinguishes N. oyapocki from N. venezuelae; the remaining cheekteeth of N. oyapocki are also absolutely smaller than their homologues in N. venezuelae. Additionally, the posterior lobe (metacone/hypocone cusppair) of M2 in N. oyapocki is greatly reduced relative to the anterior lobe (paracone/protocone) of that tooth, whereas the anterior and posterior lobes of M2 are subequal in N. venezuelae.
Fig. 38 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 38. Dorsal views and crosssections of the interorbital region in Neacomys tenuipes (A, FMNH 71778) and N. dubosti (B, AMNH 267569, holotype). In most examined specimens of N. tenuipes, the interorbital region is relatively narrow and uninflated, with weakly convergent supraorbital margins; the supraorbital beads are usually strongly reflected and seldom form projecting shelves. By contrast, the interorbital region of N. dubosti is typically broader and more inflated, the supraorbital margins are more strongly convergent, and the supraorbital beads are more frequently developed as projecting shelves.
Fig. 37 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 37. Lateral cranial and mandibular views of four species of Neacomys. From top to bottom: N. tenuipes (FMNH 71778); N. guianae (CM 76850); N. dubosti (AMNH 267569, holotype); N. paracou (MNHN 1995.1020, holotype). All views about Χ3.

Known collection localities of Neacomys paracou based on specimens examined. 1, BRA ZIL, Amapa´, Serra do Navio; 2, BRAZIL, Amazonas, 80 km N Manaus; 3, BRAZIL, Para´, Cachoeira Porteira; 4, FRENCH GUIANA, Arataye; 5, FRENCH GUIANA, Cacao; 6, FRENCH GUIANA, Cayenne; 7, FRENCH GUIANA, Mont St.Michel; 8, FRENCH GUIANA, Paracou; 9, FRENCH GUIANA, Saül; 10, FRENCH GUIANA, St.Eugène; 11, GUYANA, BarimaWaini, Baramita; 12, GUYANA, CuyuniMazaruni, Kartabo; 13, GUYANA, PotaroSiparuni, Kurupukari; 14, GUYANA, Upper Takutu Upper Essequibo, Nappi Creek; 15, SURINAM, Brokopondo, 18.5 km W Afobakka; 16, SURINAM, Brokopondo, Locksie Hattie; 17, SURINAM, Marowijne, Oelemarie; 18, SURINAM, Marowijne, Perica; 19, VENEZUELA, Bolívar, San Ignacio Yuruanı´.
Fig. 42 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 42. Ventral views of the left auditory bulla in Neacomys guianae (A, CM 76850) and N. paracou (B, MNHN 1995.1020, holotype). In N. guianae the capsular part of the auditory bulla (cap) narrows gradually to merge with the bony eustacian tube (et), and the bulla is moreorless flaskshaped. By contrast, the bulla is abruptly constricted anteromedially in N. paracou, resulting in a sharper transition between a more globular tympanic capsule and a narrower eustacian tube.
Fig. 62 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 62. Posterior palatal morphology of Rhipidomys nitela (A, AMNH 267582) and Oecomys auyantepui (B, ROM 103244). In Rhipidomys (and other ''thomasomyines''; see Voss, 1993), the palate is said to be ''short'' because the mesopterygoid fossa (mpf) extends anteriorly to or between the last molars; additionally, posterolateral palatal pits (ppp) are small or absent in ''thomasomyines''. By contrast, the palate of Oecomys and other oryzomyines is said to be ''long''

Fig. 68 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 68. Dorsal and ventral cranial views of Coendou melanurus (left, AMNH 94174) and C. insidiosus (right, AMNH 90119). All views approximately lifesize.
Fig. 36 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 36. Dorsal and ventral cranial views of four species of Neacomys. From left to right: N. tenuipes (FMNH 71778); N. guianae (CM 76850); N. dubosti (AMNH 267569, holotype); N. paracou (MNHN 1995.1020, holotype). All views about Χ3.
Fig. 57 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 57. Ventrolateral cranial views of Oecomys auyantepui (A, USNM 578015) and O. paricola (B, USNM 461389). In O. auyantepui, a bony strut of the alisphenoid (bsa) separates the buccinatormasticatory foramen (bmf) from the foramen ovale accessorius (foa), whereas in O. paricola the alisphenoid strut is absent and the two foramina are confluent (bmf 1 foa). Additionally, O. auyantepui consistently lacks the subsquamosal foramen (ssf), a prominent perforation in the posterolateral wall of the braincase that is consistently present in O. paricola and many other congeners.
Fig. 53 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 53. Plantar views of left hindfeet of Oryzomys megacephalus (A, AMNH 266527), Oecomys auyantepui (B, AMNH 267595), and Rhipidomys nitela (C, AMNH 267583) illustrating diagnostic intergeneric differences. The hindfeet of Amazonian species of Oryzomys are proportionately narrow; the three central digits (II, III, and IV) are conspicuously longer than the outer digits (I and V); digit V is not opposable; the plantar epithelium is at least partially pigmented (grayish in fresh material); the plantar pads are small, hard, and moreorless conical; and the skin between the pads is studded with small, scalelike tubercles. By contrast, the hindfeet of Oecomys and Rhipidomys are proportionately broader; digits I and V are longer relative to II–IV; digit V is semiopposable; the plantar epithelium is usually entirely unpigmented (pinkish in fresh material); the plantar pads are larger, softer, cushionlike structures; and the skin between the plantar pads is smooth or creased but never tuberculate. Despite differences in hindfoot size and other features between the illustrated examples of O. auyantepui and R. nitela, their respective genera do not seem to be consistently distinguishable by pedal morphology.
Fig. 32 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 32. Capture site of Monodelphis brevicaudata at Paracou. Our single voucher specimen was trapped in the dark cavelike space (white arrow) beneath this fallen tree in welldrained primary forest. Such cavities, carpeted and sheltered by decaying wood, are typical microhabitats for Monodelphis species but not for other Neotropical rainforest marsupials. All of the other nonvolant mammals captured under fallen trees at Paracou were rodents, including Neacomys paracou, Oryzomys megacephalus, O. yunganus, and Proechimys cuvieri.
Fig. 31 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 31. Dorsal, lateral, and ventral views of the skin of FMNH 21720, neotype of Viverra touan Shaw (= Monodelphis brevicaudata). All views approximately lifesize.
Fig. 56 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 56. Lateral cranial and mandibular views of four species of Oecomys from French Guiana. Top to Bottom: Oecomys rex (DIM 58); O. auyantepui (USNM 578015); O. bicolor (USNM 394252); O. rutilus (AMNH 267589). All views about Χ2.5.
Fig. 26 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 26. Details of palatal and upper canine morphology of Marmosops parvidens (A, AMNH 267359) and M. juninensis (B, AMNH 230016). Among other differences between these distinctive species (see text), the posterior palate is more extensively fenestrated in M. juninensis than in M. parvidens, and M. juninensis lacks the distinct accessory cusps that are always present on the unworn upper canines of M. parvidens.
Fig. 29 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 29. Distribution of body pelage on tails of Monodelphis brevicaudata (A, AMNH 93972) and M. palliolata (B, AMNH 69942). In brevicaudata, body fur extends onto the caudal dorsum for onethird or more of the length of the tail, but the caudal ventrum is only furred at the base. In palliolata and other taxa formerly synonymized with brevicaudata, the base of the tail is furred to about the same extent above and below. Both views about Χ1.2.
Fig. 47 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 47. Lateral view of the ear region in Nectomys palmipes (A, AMNH 235065) and N. melanius (B, USNM 406062). A large anterior process of the tegmen tympani (tt) that touches or overlaps the squamosal (sq) anterodorsal to the auditory bulla and anteroventral to the postglenoid foramen (pgf) is always present in N. palmipes, but the tegmen tympani is usually less exposed to lateral view in N. melanius.
