great discomfort of the poor hens, would persist in performing all 
sorts of unchicken-like manceuvres 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, 
were reared. | 
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 difficnlty 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 
sera with their countryman the Hippopotamus, so hospitably 
received. 
On some New Species or CypripINa. 
By W. Bairp, 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. CypripINA 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 
yap to resemble very much the Cypridina luteola, of Dana* from 
e Sooloo Sea. The shell, however, is ovate, not ovoid; and the 
inferior extremity, instead of being rounded, is gibbous or projecting 
anteriorly.
