Fig. 47 in Systematics Of Funnel-Eared Bats (Chiroptera: Natalidae)
Fig. 47. Distribution of relative size of the natalid organ in 10 species of Natalidae. Two groups of species can be distinguished with relation to relative size of the natalid organ: one, containing species with a relatively large natalid organ and a second containing species with a relatively small natalid organ.
Fig. 36 in Systematics Of Funnel-Eared Bats (Chiroptera: Natalidae)

Fig. 42. A in Systematics Of Funnel-Eared Bats (Chiroptera: Natalidae)
Fig. 42. A, Canonical analysis axis scores for four limb measurements of 12 species of Natalidae. Loading contributions of variables to each axis is shown in table 3. CI is an axis of body size and CII is an axis of wing-tip shape, with bats on the positive side of the axis having more pointed tips. Scores of canonical analyses are shown in table 25.
Fig. 34 in Systematics Of Funnel-Eared Bats (Chiroptera: Natalidae)
Fig. 34. Canonical variates analyses (CVA) scores for external (A) and cranial (B) measurements of populations of Natalus stramineus from 6 Lesser Antillean islands: (N) Antigua + Barbuda, females; (&) Antigua + Barbuda, males; (X) Anguilla, males; (N) Montserrat + Saba, females; (&) Montserrat + Saba, males; (#) Guadeloupe, females; (%) Guadeloupe, males. Axes are scaled relative to their eigenvalues. The first canonical axes can be interpreted as a measure of the length of the 3rd metacarpal (A) and of breadth across canines (B; table 21).
Fig. 16 in Systematics Of Funnel-Eared Bats (Chiroptera: Natalidae)
Fig. 16. Geographic variation of Chilonatalus micropus. SAP: San Andrés and Providencia islands, Colombia (12 females, 24 males); Jam: Jamaica (19 females, 29 males); Hisp: Hispaniola (2 females, 4 males). Mean braincase breadth of the sample from Hispaniola was larger but the difference was not statistically significant. The sample from Jamaica was larger in most external dimensions (Tukey, P, 0.05), most notably in length of 5th metacarpal, length of penis, and length of natalid organ. Symbols: black dots, means; vertical gray bars, two standard deviations around the mean; vertical black line, two standard errors around the mean.
Fig. 18 in Systematics Of Funnel-Eared Bats (Chiroptera: Natalidae)
Fig. 18. Morphometric variation among two island populations of Chilonatalus tumidifrons. Islands: Aba 5 Abaco (1 female, 19 males); Sal 5 San Salvador (12 females, 20 males). On average, males from Abaco had significantly deeper braincases than males from San Salvador (Tukey, P, 0.05). Symbols: black dots, means; vertical gray bars, two standard deviations around the mean; vertical black line, two standard errors around the mean.
Fig. 21. A in Systematics Of Funnel-Eared Bats (Chiroptera: Natalidae)
Fig. 21. A, Plot of means (black dots), two standard deviations around the mean (gray bars), and two standard errors of the mean (vertical black lines) of greatest skull length of Natalus espiritosantensis from five geographic areas: (A) Bolivia (5 females, 6 males); (B) SW Brazil [Mato Grosso do Sul], Paraguay (4 females, 6 males); (C) SE Brazil (Espirito Santo, Goiás, Minas Gerais, São Paulo; 7 females, 7 males); (D) NE Brazil (Ceará, Bahia, Rio Grande do Norte; 4 females, 2 males); (E) N Brazil (Pará; 2 males). Although the observed mean greatest skull length of males from NE Brazil was smaller, the difference was not statistically significant (MANOVA, P. 0.01). B, Plot of canonical scores for 6 cranial measurements of N. espiritosantensis from five geographic areas (same as above). Variable loadings are listed in table 12. The lack of morphometric separation between distant geographic units of N. espiritosantensis is congruent with the morphological homogeneity of the species (see text).
Fig. 38 in Systematics Of Funnel-Eared Bats (Chiroptera: Natalidae)
Fig. 38. Plot of wing-tip shape index vs. relative size of the uropatagium in 11 species of Natalidae. Five different ecomorphs are formed by the intersection of these two indices. The genus Natalus is the most diverse in flight morphology, with most species clustering in the intermediate wing tip and large uropatagium ecomorph and two outliers: (1) Natalus primus, which clusters with two species of Chilonatalus, and (2) Natalus lanatus, whose broad wing tip is unique among natalids.
Fig. 17 in Systematics Of Funnel-Eared Bats (Chiroptera: Natalidae)
Fig. 17. Holotype of Chilonatalus tumidifrons (USNM 122024, male, San Salvador, the Bahamas). Scale bar 5 5 mm.
Fig. 26 in Systematics Of Funnel-Eared Bats (Chiroptera: Natalidae)
Fig. 26. Sexual and geographic variation in four cranial dimensions of Natalus lanatus from the Atlantic and Pacific versants of the Mexican highlands. Geographic areas: A 5 Atlantic (Veracruz; 8 males, 5 females); P 5 Pacific (Chihuahua, Durango, Jalisco, Nayarit; 18 males, 19 females). Symbols: black dots, means; vertical gray bars, two standard deviations around the mean; vertical black line, two standard errors around the mean. Females have narrower breadths across canines in both geographic areas (MANOVA, P, 0.05) whereas individuals (regardless of sex) from the Atlantic versant have longer forearms and wider skulls than individuals from the Pacific versant (Tukey, P, 0.05).
Fig. 12 in Systematics Of Funnel-Eared Bats (Chiroptera: Natalidae)
Fig. 12. Geographic variation of Nyctiellus lepidus. Cuba (N 5 17) includes specimens from La Habana, Isla de la Juventud, and Granma. The Bahamas (N 5 37) include specimens from Cat, Eleuthera, Little Exuma, Long. All specimens are male. Specimens from Cuba have slightly longer forearms but have narrower skulls and smaller rostra (Tukey, P, 0.05). Symbols: black dots, means; vertical gray bars, two standard deviations around the mean; vertical black line, two standard errors around the mean.
