 row (exclusive of incisors) 9. 



Teeth. The teeth are slightly larger than in P. sezekortu or P. bombi- 

 fi-ons. Crown of first upper molar nearly equal in length to that of sec 

 ond and third together. First upper premolar minute, usually closely 

 wedged between canine and second premolar. Second premolar larger 

 than second molar. First lower molar nearly double as long as first lowf r 

 premolar ; second premolar slightly larger than first, which is about equal 

 to third molar.

Phyllonycteris bonabifrons sp. nov. 



Type, adult tf (in alcohol), No. 86274, United States National Museum, 

 collected in a limestone cave near Bayamon, Province of San Juan, Puerto 

 Rico, January 18, 1899, by Paul Beck with. 



General characters. See synopsis. 



Ears. In size and form the ears are as in P. planifrons. Tragus shorter 

 and broader than in P. planifrons, the anterior border strongly convex, 

 and with from one to three pointed outgrowths above middle. Posterior 

 border much more conspicuously denticulate than in P. planifrons. 



Muzzle and chin. The muzzle and chin are essentially as in the Baha- 

 man species, but the ridge back of the noseleaf is separated from the latter 

 by a much broader groove, and the fleshy outgrowths from the sides of 

 the groove in chin are more conspicuous. 



Membranes, feel, tail, and fur as in P. planifrons. 



Color. Both fur and membranes are much darker than in P. planifrons. 

 In a specimen (No. 86270) skinned after only two months' immersion in 

 formalin and alcohol, the fur of the dorsal surface is whitish gray through 

 basal two thirds, then mars brown to tip. Ventral surface pale wood 

 brown. Ears, feet, and membranes dark brown. 



Skull. The skull of Phyllonycteris bombifrons differs from that of P. plani 

 frons in its shorter, narrower, more rounded rostrum, and larger, much 

 more highly arched braincase. The proencephalon rises above the plain 

 of the rostrum at an angle of about 30. Lachrymal swellings well de 

 veloped. Audital bulhe smaller than in P. planifrons, the greatest diam 

 eter of each considerably less than least width of palate between second 

 premolars. Ptertgoids slightly shorter than in P. planifrons. Rim of ex 

 ternal nares thin and noticeably flaring. Mandible slender. 



The skull of the type measures : greatest length 24.4 ; basal length 22 ; 

 basilar length 19.8 ; zygomatic breadth 12; interorbital breadth 5; lach 

 rymal breadth 6; mastoid breadth 11.4; fronto-palatal depth 3; depth
