170 On a new Stenodermatous Bat from Trinidad, 



But not only has Vampyrops pusillus (as it should be called) 

 no cleft, but Mr. Dobson's ^^ Chiroderma hidens''^ is also without 

 it ; and since there appears to be no generic importance in the 

 other characters of Chiroderma as mentioned by him, I propose 

 that the two species just referred to should be shifted to Vam- 

 pyrops, which would then contain all the members of this 

 group of bats with obUque incisors and perfect nasal regions. 



The genera to which the new Trinidad bat is most nearly 

 allied may therefore be arranged as in the following synop- 

 sis : — 



A. Palate continued some way behind molai'ss. 



a. Middle upper incisors vertical 1. Artibeus. 



b. Middle upper incisors oblique. 



a'. Nasal region not cleft , 2, Vampyrops. 



b'. Nasal region cleft 3. C'hiruderma. 



B. Palate not continued backwards behind molars. 



c. Palate emarginate to level of — ^— . Crown not un- 



usually elevated 4. Ste7iodenna. 



Ill 3 



(I, Palate emarginate to level of — ^. Crown much 



elevated above muzzle 5. Atnctrida *. 



The enlarged genus Vampyrops may then be arranged as 

 follows : — 



A. Molars ^. 



«. Forearm about 60 millim. Front of ca- 

 nine to back of '^^ 12-13 miUim 1, V. vittatus, Ptrs.t 



b. Forearm 52 millim 2. V. infuscus, Ptrs. 



c. Forearm 35-43 millim. Front of canine to 



back of -^ about 8 millim 3. V, lineatus, Geoll'. 



B. Molars 3- 



d. Incisors "-. Front of canine to back of -^—

 very doubtfully separable.
