1890.] ON BUTTERFLIES FROM CENTRAL AFRICA. 463 



what he thought was a stick projecting a few inches above the sandy 

 bottom, and he broke it off and gave it to one of my native collectors 

 who was with him, and who recognized it as being the broken piece 

 of an animal. The divers then hunted for and secured other speci- 

 mens, iill of which had their terminal bulbs in a perfect condition. 

 The largest specimen, which I have just re-examined, is 16 inches 

 in length, and tapers towards the upper end, but the extreme tip is 

 wanting. The diver described the animals as sticking straight up 

 in the sand, and said that, as soon as he touched them, they went 

 deeper and deeper down in the saud, and sometimes fixed themselves 

 so firmly that he could only secure them by digging them out with 

 a spade. 



" Though I was not present at the capture of the specimens I have 

 no reason to discredit the evidence of the diver, who is a keen ob- 

 server, wliolly unacquainted with the English language, and who has 

 certainlj- never seen or heard of the ' .Journal of Researches.'

The Secretary called attention to a pamphlet presented to the 

 Society's Library by M. P. A. Pichot, C.M.Z.S.,' giving an account 

 of the localities in which the Beaver {Castor fiber) is at present found 

 in the Camargue or Delta of the Rhone, and exhibited a map for- 

 warded by M. Pichot in which these localities were exactly shown. 



Mr. W. T. Blanford, E.R.S., exhibited a photograph, lent by 

 Mr. A. B. Wynne, of a specimen of the Indian Gaur {Bos gaurus) 

 recently killed, and made some remarks on this animal. 



The following papers were read : — 



1. A List of the Butterflies collected by Mr. William Bonny 

 ou the Journey with Mr. Stanley from Yambuya on the 

 Aruwimi River through the Great Forest of Central 

 Africa; with Descriptions of nine new Species. By 

 H. Grose Smith, F.Z.S. 



[Eeeeived June 16, 1890.] 



This collection of Butterflies being the first which has been 

 received in Europe from the Great Forest, a complete list of the 

 species which it contains is given. It will be seen that, with the 

 exception of the species described as new and a few others, the 

 collection consists of species for the most part common on the West 

 Coast, very few species peculiar to the East Coast being comprised 

 in it.
