Dr. J. E. Gray on species of Mammalia from the Aru Islands. 219 



extending a little beyond the end of the truncated interfemoral mem- 

 brane. 



Cutting teeth ~- ; upper large, chisel-shaped, separated by a 

 small space from each other and from the canines ; the lower small, 

 crowded, three -lobed; canines conical ; grinders ? 



The specimen is unfortunately rather injured about the face ; but 

 it appears quite distinct in form from any of the Horse-shoe Bats I 

 have hitherto observed. 



This species appears to be quite distinct from Hipposideros 

 speoris of Timor, which is described as being a little larger than the 

 larger English Horse-shoe Bat, Phyllorhina bifer ; it has the follow- 

 ing synonyma : — 



Vespertilio speoris, Schneid. in Schreb. Saugth. t. 59 B. ; Shaw, 

 Zool. i. 147. 



Jthinolophus marsupialis, Geoff. Cour. 1805. 



Rhinolophus speoris, Geoff. Ann. Mus. xx. 261. t. 5. 266 ; Desm. 

 N. D. H. N. xl. 368; Mam. 126; Fischer, Mam. 139. 



Rhinolophe crumenifere, Peron & Lesueur, Voy. aux Terres Aust. 

 Atlas, i. t. 35. 



Hab. Timor {Peron and Lesueur). 



It is certainly distinct from Hipposideros insignis, Gray, Mag. 

 Zool. & Bot. ii. 492, the Rhinolophus insignis, Horsf. Java, Vesp. 

 cy elope, Deschamps, MSS., from Java, which Fischer confounded 

 with the former, and which has acute ears on the sides of the face, 

 numerous lamellae under the front part of the nose-leaf, and is 

 13^ inches in expanse of wings.
