membrane considerably more than length of tail. Upper surface of 

 uropatagium thinly furred to line of tip of tail. Lower surface of 

 uropatagium rather thickly sprinkled with short hairs along veins 

 except near legs. Wings naked except where fur of body extends 

 both above and below to line joining middle of humerus with lower 

 third of femur. 



Fur and color. — Fur of middle of back about 11 mm. in length. 

 Face and muzzle practically naked. Fur of head covering basal 

 third of ears. 



Dorsal surface uniform dark sepia ; under parts much paler, very 

 near the broccoli brown of Ridgway. Hairs everywhere, both above 

 and below, indistinctly whitish at base. Muzzle, ears and mem- 

 branes blackish. 



Feet. — The feet are slender, a little less than half as long as tibia 

 and considerably more than half as long as calcar. Calcar slender, 

 weak and ill-defined, 3-5 mm. shorter than tibia, terminating in a 

 small lobe. 



Skull. — Skull thin and papery ; muzzle about J as wide as brain 

 case, slightly inflated laterally, and with a deep central longitudinal 

 groove ; postorbital processes long and very slender, reaching almost 

 to highest point of zygomata; brain case strongly inflated poste- 

 riorly. Measurements of two skulls: No. 83,574, 9 adult ; greatest 

 length, 14; basilar length, 10.4; zygomatic breadth, 8.8; greatest 

 anteorbital breadth, 5.8 ; palatal length, 4 ; width of palate between 

 posterior molars, 3.4 ; length of upper tooth row (exclusive of in- 

 cisors) 5.2 ; mandible, 9.6 ; lower tooth row (exclusive of incisors), 

 5.6. No. 83,556, $ adult ; greatest length, 14 ; basilar length, 10.4 ; 

 zygomatic breadth, 9 ; greatest anteorbital breadth, 5.4 ; length of 

 postorbital process, 3 ; palatal length, 4 ; width of palate between 

 posterior molars, 3 ; length of upper tooth row (exclusive of incisors), 

 5.2 ; mandible, 9 ; lower tooth row (exclusive of incisors) 5.4. 



Teeth. — The teeth are essentially as in the E. monticola of Dobson, 

 except that the first upper premolar is tightly wedged between the 

 canine and second premolar, and the first lower premolar is very 

 much smaller than the second in cross section. 



General remarks. — Emballonura peninsitlaris needs comparison 

 with only one species, the E. monticola of Temminck. 4 I have seen 

 no specimens from Java, the type locality of this form, but Tem-
