64 Miller Seven New Malayan Bats. 



dible, 52.6; maxillary toothrow exclusive of incisors (alveoli), 25 ; man- 

 dibular toothrow exclusive of incisors (alveoli), 28.6. 



Specimens examined. Fourteen, all from Bawean. 



Remarks. The specimens show no special variations either in color or in 

 size. The shortest forearm that is certainly uninjured measures 151 mm. 

 This is decidedly the largest member of the Pteropus hypomelanus group 

 yet discovered. Its size and dark color readily distinguish it from its 

 allies. 



Pteropus niadicus sp. nov. 



1889. Pteropus nicobaricus Modigliani, Ann. Mus. Civ. di Stor. Nat. di 

 Geneva (2) VII, p. 239. 



Type. Adult male (skin and skull). No. 141,233, United States Na 

 tional Museum. Collected at Teliwaa, Nias Island, west Sumatra, 

 March 5, 1905, by Dr. W. L. Abbott. Original number, 3981. 



Characters. Similar to Pteropus nicobaricus (Zelebor), but with back gray 

 instead of black, and head not darker than mantle. 



Color. Type : Back a grizzled gray rather closely resembling the hair- 

 brown of Ridgway, with a slight yellowish cast along sides and a darker 

 wash in median region. Mantle light russet heavily clouded with blackish, 

 the latter predominating. On head the black is less noticeable and the 

 russet becomes paler, so that the mantle is noticeably darker than the 

 head. Underparts blackish anteriorly, russet along middle of chest and 

 belly, light hair-brown on flanks and under side of thighs. Ears and 

 membrane black. 



Skull and teeth. The skull and teeth do not differ appreciably from those 

 of Pteropus nicobaricus. 



Measurements. Type : Head and body, 270 ; tibia, 68.4 ; foot, 52.4 ; fore 

 arm, 152.4; thumb, 66.2; second finger, 114; third finger, 287; fourth fin 

 ger, 234 ; fifth finger, 205 ; skull, upper length, 69 ; condylobasal length, 

 69.4; median palatal length, 34.8; zygomatic breadth, 38.2; interorbital 

 constriction, 9.8; postorbital constriction, 8 ; breadth of braincase, 23.6;

 mandibular toothrow exclusive of incisors (alveoli), 30.4. 



Specimens examined. Three, all from Nias Island. 



Remarks. Though nearly related to Pteropus nicobaricus this species is 

 easily distinguishable by its gray back and light colored head. In ten 

 skins of Pteropus nicobaricus the head is without exception conspicuously 

 darker than the mantle, while the back is almost black.
