Ti/pe B.M. 1.0. 99. 12. 3. 1. Collected 5th April, 1899, 

 by Mr. A. S. Meek. 



This fine species may be readily distinguished from its 

 ally C. major by its larger size, striking coloration, and (if 

 that organ is perfect) shorter tail. Like tiiat species, it no 

 doubt belongs to the subgenus " Bde{i/qma,^^ separated by 

 Dr. Matschie from the typical Cepha/otes ; but I confess I 

 can see no sufficient reason for subdividing the genus. The 

 second lower premolar in some specimens of C. cephalotes has 

 the second cusp said by Dr. Matschie to be characteristic of 

 Bdelygma. 



It may also be noted that of specimens referred to C. cepha- 

 lotes those from Celebes, Amboina, and Timor Laut have 

 markedly larger skulls and longer forearms than those of the 

 rest of the Papuan subregion. The smaller form should 

 apparently be distinguished under the name of G. albiventer. 

 Gray. Of this latter the Museum possesses examples from 

 ]\lorty Island (type), Admiralty Islands, Key Islands, British 

 New Guinea, and Cape York. Whether its range overlaps 

 that of the larger C. cephalotes remains to be proved. 



With the Cephalotes Mr. Meek has sent home a number of 

 specimens of Pipistrellus papuanus, Pet., and these prove that 

 the species is subject to the peculiar form of erythrism already 

 described in several other bats, some of the specimens being 

 bright rufous, while others are dark brown. 



Another species discovered by the same collector, Enhallo- 

 nura 3feeki, Thos., found by him in the Trobriand Islands, 

 has recently turned up in a somewhat distant locality, namely 

 in the Key Islands, where it occurs in the same collection as 

 the remarkable Rhinolophus acMlles described in the last 

 number of the 'Annals.'
