THECRANIALAND DENTAL CHARACTERS OF CHILOPHYLLA* 



A small leaf-nosed bat representing the new genus ChilophylM was 

 collected by Dr. Edgar A. Mearns on the Alag River, Mindoro, in De- 

 cember, L906. The skull and body <>f this specimen have been mislaid 

 or lust, and the cranial and dental characters of the genus have not yet 

 been described. <>n July 6, 1911, Mr. Arthur de C. Sowerby obtained a 

 second skin of Chilophylla at Port Swettenham , Federated Malay States. 

 Externally this specimen (adult male, No. 175,000 U. S. N. M.) agrees 

 so exactly with the type of C. hirsuta that I can detect no peculiarities 

 that seem of specific importance. Its measurements, compared with 

 those of the type (adult female) in parenthesis are: bead and body, L'!t 

 (33); tail,— (7); tibia, 13.6(13.6); foot, 6.2 (6.4); forearm, 34.2 (33.8); 

 thumb, 8.2 (8.2); its metacarpel, 6.2 (6.2); second finger, 33 (32); third 

 finger: metacarpel, 20 (L'4.2); first phalanx, 6 (6.2); second phalanx, 

 22(22); fourth finger: metacarpel, '21 (25.4); first phalanx, 7.d (7.8); 

 second phalanx, '.M' (8.6); fifth finger: metacarpel, 29 (27.4); first 

 phalanx, 8.8 (8.4); second phalanx, 9 (10.2); ear from meatus, 14 (12); 

 condylobasal length of skull, 13.0; zygomatic breadth, <>.<>; breadth across 

 nasal swellings, :'>.(i; ihterorbital constriction, L'.O; breadth of braincase, 

 (1. 4; mandible, 8.2; maxillary toothrow, 4.8; mandibular toothrow, 5.0. 



The skull of this specimen is perfect. It furnishes the following char- 

 acters to complete the diagnosis of the genus: Skull like that of a small 

 Hipposideros in general features, but with nasal swellings very small 

 (even more reduced than in Cloeotis ; practically the entire swelling lies 

 behind level of antorbital foramen), and maxillaries and premaxillaries 

 conspicuously produced anteriorly, the length of premaxillary fully twice 

 median length of palate, the distance from level of front of canines to 

 upper margin of nares about l 1 ^ times that from upper margin of nares 

 to narrowest portion of interorbital constriction. Dental formula as in 

 Hipposideros; upper canine strongly projecting forward, its shaft with 

 large anterior and posterior secondary cusps, the points of which lie in 

 same horizontal plane as points of paracones of molars; large premolar 

 more reduced than in the related genera; posterior lower premolar with 

 shaft compressed laterally, the form of the cusp without evident resem- 

 blance to that of protoconid of first molar.
