Fig. 86 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 86. Results of pitfall trapping at Paracou, where 45 captures representing 12 species of marsupials and rodents were recorded with 2783 bucketnights of effort in 1993.
Fig. 72 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 72. Fenestration of the bony roof of the mesopterygoid fossa in typical examples of Myoprocta acouchy (A, AMNH 266566) and M. pratti (B, FMNH 125085). The sphenopalatine vacuities (spv) are usually present only as narrow (<1 mm) slits in the bony roof of the mesopterygoid fossa of M. acouchy, but in M. pratti these fenestrae are wider, teardropshaped apertures.

Fig. 71 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 71. Unvouchered photographs of living Coendou melanurus (top) and C. prehensilis (bottom, not to same scale) from Petit Saut, French Guiana (ca. 28 km SSW Paracou). Both animals are alarmed, so the pale bases of their erected quills are exposed. When C. melanurus is not alarmed and defensive, its short bicolored (blacktipped) quills are hidden beneath a dense coat of long fur (see fig. 67). By contrast, the large tricolored (whitetipped) quills of C. prehensilis are always visible because the short sparse fur of this species is concealed among the quill bases. Also note the diagnostically bulging forehead and swollen muzzle of C. prehensilis, and the equally diagnostic blackish caudal bristles of C. melanurus. From color transparencies by J.C. Vie´.
Fig. 67 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 67. External morphology of Coendou melanurus (left, AMNH 266565) and C. insidiosus (right, AMNH 90119). Although these species are similar in possessing short bicolored quills concealed by long fur, C. melanurus has a much longer tail relative to headandbody length, and its coarse blackish dorsal fur is heavily streaked with yellow or whitetipped guard hairs; the caudal bristles (covering the tail between its furry base and naked prehensile tip) are jet black. By contrast, C. insidiosus is relatively shortertailed and has softer smokygray (or whitish) dorsal fur without contrastingly colored guard hairs; the caudal bristles are brownish, not black. Both views approximately Χ0.3.

Fig. 51 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 51. Pitfall trapline that captured Neusticomys oyapocki in creekside primary forest at Paracou. This trapline roughly paralleled the small stream illustrated in figure 9, which was only about 10 m to the right of this view.

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.
Fig. 41 in The Mammals Of Paracou, French Guiana: A Neotropical Lowland Rainforest Fauna Part 2. Nonvolant Species
Fig. 41. 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''
