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

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

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

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

 ing ; this variation may occur on the two chelae of an individual. 

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

 Smith and by Miss Rathbun, has the carapace 21 mm long ; 28 mm 

 wide ; ratio 1 :1.33.

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

 be really distinct.

 from the post-ocular tooth by a rather deep sinus, which, however, 

 does not divide the coalesced tooth to its base. Front produced,
