of the utmost value, and increasing very considerably the interest 

 of the specimens. 



1. AnTHEOPOPITHECUS TE0GL0DYTE8, Gm. 



a. S ' " Skull of a full-grown Chimpanzee sliot by me in Mssou- 

 gua, shores of Albert Lake, the first specimen ever obtained in 

 these regions." — E. 



h. 2 . SkuU without mandible. No exact locality. 



Specimen a is an unusually fine male skull, measuring 198 millim, 

 from occiput to gnathion, and 138 iu its greatest bi-zygomatic 

 breadth. 



There appears to be no essential difference between it and 

 ordinary West- African Chimpanzee's skuUs ; and in regard to " Tro- 

 glodytes schiveinfurtJd '' and " T. niger var marungensis" I can 

 only repeat my opinion of 1888 \ namely, that the evidence is as 

 yet too meagre for their proper distinction. 



2. Heepestes galera, Erxl. 



S . Monda, Nguru Mountains. 



A remarkably handsome specimen, strongly influenced by ery- 

 thrism, many of the hairs, especially those on the belly, being 

 wholly or partly of a brilliant rufous colour. 



3. Helogaie paevtjla undttlata, Peters. 



a. $ . Usambiro, S. Victoria Nyanza. 1/9/89. 



b. d. Usagara. 22/11/89. 



" Iride fusca. Native names (a) " Ndjororo " and (b) " Viguiri." 

 Common in little flocks of from 6 to 10 individuals, running about 

 the fields."— E. 



Although, on the whole, I am disposed to agree with Dr. Jentink^ 

 as to the specific identity of H. parvula, Sund., and H. undulata, 

 Peters, yet the difference in the colour of typical examples of each 

 is such as to render it advisable to consider the two as representing 

 different geographical races — a southern semi-tropical, and a northern 

 tropical one respectively. 



Dr. Emin's observation as to the gregarious habits of the species 

 is of remarkable interest, and is, I believe, the first observation of 

 the sort made about any member of the family.

a. Mandera. 3/90. Coll. Langheld. 



The present is the third specimen of this rare species that has 

 been received by the Museum. The first was obtained on the 

 island of Zanzibar by Sir John Kirk in 1884; and a second one, a 

 fine male in spirit, in the llabai Hills, Mombasa, by the Rev. W. E. 

 Taylor in 1886. All the three agree precisely with the original 

 description given by Prof, du Bocage ^, of which an abstract was 

 published by Dr. Giinther in his monograph of the genus ■*.
