the fourth ; the fifth is often smaller than the fourth. The front is 

 a little more produced m the middle and is more evidently 4-lobed, 

 the outer small lobe being more distinct. The distal groove on the 

 carpns is sometimes distinct, but ill-defined ; in other cases it is lack-

 A Brazilian specimen (No. 236, Yale Mus.), studied both by Prof. 

 Smith and by Miss Rathbun, has the carapace 21™'° long ; SS™"" 

 wide ; ratio 1 : 1.33.

Some of our Bermuda specimens may belong to this species, if it 

 be really distinct.
