great discomfort of the poor hens, would persist in performing all 

 sorts of unchicken-like manoeuvres with their large beaks and ex- 

 tended wings in a small artificial pool constantly supplied with water 

 by several negresses retained in my service for their especial benefit. 

 Negro boys of the tribe (the Raik) were also employed to supply 

 their little pond with live fish, upon which, and occasionally the 

 intestines of animals killed for our use, chopped into small pieces, 

 they were reared. 



As may be supposed, the birds became the pets of my " Bizouks," 

 as 1 frequently called my Khartoumers ; and as they grew up, with 

 extended wings and a rattle-like noise produced by the snapping of 

 their bills, they would follow them round the large enclosure of my 

 camp. 



During their journey to England, six months* confinement in a cage 

 has greatly affected their health, and I dare say soured their tempers ; 

 at least, such to a certainty would be the effects on myself if placed 

 in a similar predicament. But, in common with, I venture to say, 

 every one connected with the Society, I trust that my attention and 

 trouble, to say nothing of the expense which I have been put to — 

 although perhaps a more important feature than most of you may 

 be aware of — may be rewarded by their recovery and well-being ; and 

 I hope if, as there will be no difficulty on my part, they become the 

 property of the Society, they will long live to adorn, and perhaps 

 enhance, the merits of the rare collection amongst which they are at 

 present, with their countryman the Hippopotamus, so hospitably 

 received* 



On some New Species of Cypridina. 

 By W. Baird, M.D., F.L.S. 



Of the new species about to be described, one is a native of 

 Europe, two of the Indian Ocean, and one of Australia. 



1. Cypridina norvegica, Baird. 



Carapace-valves oval, somewhat compressed, smooth and shining. 

 The notch or sinus at the anterior extremity is not deep ; the beaks 

 are small and somewhat thickened round the margins. The dorsal 

 margin is gently rounded ; the ventral is slightly arched, projecting 

 at its upper extremity immediately beneath the notch, and at its in- 

 ferior extremity is rather sharply gibbous or prominent, which, seen 

 from the internal surface, shows a duplicature of the shell. The 

 surface is polished, not punctured, and is of a straw-colour. In shape it 

 appears to resemble very much the Cypridina luteola, of Dana* from 

 the Sooloo Sea. The shell, however, is ovale, not ovoid; and the 

 inferior extremity, instead of being rounded, is gibbous or projecting 

 anteriorly.
