CAPRELLA AQUILIBRA. 73 
Say says, is not constant), situated immediately posterior 
to the process. The last three pairs of legs are very 
short. 
Having had the opportunity of comparing our British 
specimens with that presented to the British Museum by 
Mr. Say, we are enabled to assert their identity, and we 
are not able to detect any character by which this species 
differs from C. Januarii, as described by Dana and 
Kroyer. We have also seen specimens from Hong-kong, 
and are unable, by the closest observation, to discover 
any difference between them. 
The geographical range of this species is, therefore, 
very great. In our own country we took it first amongst 
weeds attached to one of the buoys in Plymouth Sound. 
It has since been sent to us from Seaham by the Rev. 
A. M. Norman, who has also taken it at Cullercoats. But 
Kréyer’s type came from Rio Janeiro, while Dana’s 
specimens were procured from an anchor in from ten to 
twelve fathoms of water, also at Rio Janeiro. Mr. 
Harington has sent specimens to the British Museum, 
which he procured at Hong Kong, and Say found his 
specimens ‘‘very common in the bay of Charleston, 
particularly at Sullivan’s Island, on the two species of 
Gorgonia, so common in the salt-water creeks of the 
southern coast.”
