MAMMALS COLLECTED BY DR. W. L. ABBOTT 235 



Burmah by Thomas, under the name Rhinolophiis affinis rouxii. In 

 size it agrees with the measurements of the Burman specimens; while 

 the ridge beneath the free margin of the noseleaf is much more de- 

 veloped than in Rhinolophus affinis^ and might readily be described 

 as a supplemental leaflet. Without further material it is impossible 

 to decide whether the island species is identical with that from the 

 peninsula, or whether either is the same as the animal described 

 by Temminck. That all three are closely allied there can be no 

 doubt. 



RHINOLOPHUS MINUTUS sp. nov. 



Type. — Adult male (in alcohol). No. 101715 United States National 

 Museum, Pulo Siantan, Anambas Islands, September, 1899. 



Chat-acters, — Similar to Rhinolophus minor Horsfield, but with 

 shorter ear and tibia. First lower premolar in contact with third. 



Color. — General color broccoli-brown, somewhat lighter below than 

 above, the hairs everywhere with glossy pale tips, these most notice- 

 able on underparts. Ears and membranes blackish brown. 



Skull a?zd teeth. — The skull is smaller than that of a specimen 

 of Rhinolophus minor from the mainland of India, and the brain- 

 case is more narrow, but otherwise no important differences are 

 apparent. Teeth as in R. minor., but first and third lower premolars 

 strongly in contact, the second, therefore, wholly external to the tooth 

 row. 



JMeasu.re7nents. — For external measurements of Rhinolophus min- 

 utus see table, page 240. 



Cranial measurements: greatest length 15 ; basal length 13.4; basi- 

 lar length ii.S; zygomatic breadth 7.8; least interorbital breadth 

 2; mastoid breadth 7.8; greatest length of braincase 9.6; greatest 

 breadth of braincase above roots of zygomata 6.8 ; frontopalatal depth 

 (at middle of molar series) 3 ; depth of braincase 5 ; maxillary tooth- 

 row (exclusive of incisors) 6.2; mandible 10,2; mandibular toothrow 

 (exclusive of incisor) 6.4. 



Specijnens examined. — Two (both in alcohol) : one from Pulo Sian- 

 tan, the other without definite locality. 



Remarks. — Although this species is closely related to Rhinolophus 

 minor its differently proportioned leg and foot appear to present suf- 

 ficient reason for its recognition as a local form. The measurements 

 of the type as given by Dobson show that Rhinolophus niinor from 

 Java (the type locality) agrees in proportions with specimens from 

 the mainland.
