ZOOLOGICAL LITERATURE. 
0. Molars Xiroderma (subg. n.) j with A, fallax (sp. n.), A. con- 
color (sp. n.), and A. personatus (Wagl.). 
2. Pht/Uops. Molars | ; palate deeply excised; to between the molars j with 
P. albo?naoulatm (Gundl.) and P. undatus (Gervais). 
3. Vampyrops. Skull and palate as in Artiheus j molars similar to those 
of Stumira j with P. Uneatum (Geoffr.) and V. vittatus (Pet.). 
? 4. JStenodenna (Geoff.). Molars ^ ; the dentition; according to Geoffroj; 
appears to be very similar to that of Vampyrops } the author is uncertain 
whether the absence of the small hinder molar is a peculiar character; or de- 
pendent on young age only. 
6. Pygoderma (Ptrs.). Molars j; the fourth very small ; facial portion of 
the skull very high j with P. hilahiatum (^agn.). 
—^6. Ametrida (Gray). Teeth as in Pygodet'ma ] facial portion of the skull 
much flattened^ with A. centurio (Gray). 
7. CMrod(n'ma (Peters); with C. villosum (Pet.) and C. p)usillum (Wagn.). 
8. Stu7'uira (Gray), with P. liliimi (Geoffr.) and /S', chilensis (Gerv.). ‘ 
. 9. Brachyphylla (Gray) j with B. cavei'nai'imi (Gray). 
^0. Centurio (Gray) j with C. senex (Gray) and C. m^murtrn (Allen). 
Ai'tibeus fallax^ sp. n.; PeterS; Monatsber. Akad. Wiss. Berl. 1865; p. 365. 
Extremely similar to A. perspicillatus, but with the lower border of the horse- 
shoe-shaped appendage longer, more distinct, and finely notched. Molars 
-g-. Coloration variable as in A. perspicillatus. Guianas. 
Artibeus concolor, sp. n., Peters, 1. c. p. 357. Much smaller than the pre- 
ceding. Nasal appendage not notched on its lower free border. Ears and 
wing-membranes as in -4. perspicillatus. Molars j. Uniform brown, paler 
below. Total length to the edge of the interfemoral membrane 85 millim. 
From Paramaribo. 
Artibeus (Der^nanura) guadrioiUatus, sp. n., Peters, Monatsb. Akad. Wiss. 
Beii. 1865; p. 358. Of the size and appearance of Stenoderma toltecum (Sauss.), 
with which it also agrees in the nasal appendage and ears ; interfemoral mem- 
brane less broad and less hairy. Brown above, paler below, with four white 
longitudinal stripes on the head. The fourth lower molar but little shorter 
than the third. Total length of a specimen not quite adult, 80 millim. From 
Surinam. 
Ai'tibeus perspicillatus (L.) and A. h'achyotus (Neuwied). On their habits 
see Osburn, Proc. Zool. Soc. 1865, pp. 64 and 81. 
■\Ceniurio senex (Gray). C. Jiavogidaris (Licht., Pet.) and C. mexicanus 
(Sauss.) are identical with this species. Peters, 1. c. p. 625. 
XDesmodtcs rufus. Prof Huxley describes and figures the very extraordinary 
form of its stomach, the cardiac portion of which is prolonged into an exceed- 
ingly long diverticulum, the pyloric division being very short. Proc. Zool. 
Soc. 1866, p. 386. On this occasion the author suggests a division of the 
Chiroptei'a into three primary groups, viz. Frugimra, Insectivoi'a, and Ilcema- 
tuphilina ; the last group would comprise Desmodus and DiphyUa.
