Some specimens, taken by the Eev. A. M. Norman off the 

 coast of Northumberland, agree so closely with the description 

 and figures of Kroyer above referred to, that we have little 

 doubt but that they belong to the species which he has de- 

 scribed under the above name. The form of the hand of the 

 second pair of gnathopoda, of which we give a figure, bears 

 such a relation to that which we have described as belonging 

 to M. poUeximia, that we are inclined to believe that Kroyer's 

 specimen may be but the female of ours. But this is yet to 

 be determined, in which case our species would yield its name 

 to the earlier one of Kroyer.
