CAPRELLA .EQUILIBRA. 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 

 Kroyer'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 "vei-y common in the bay of Charleston, 

 particularly at Sullivan's Island, on the two species of 

 Gorgotiio, so common in the salt-water creeks of the 

 southern coast."
