PLATE X, FIGURES i li; 2, a-c ; 3; 4; 5. 



The two teeth on the dorsal carina of the carapace are widely 

 separated, the posterior one being the larger, acute, hooked, and 

 situated at about the posterior fourth of the carapace; the other 

 is close to the base of the rostrum, near the first rostral tooth, and 

 similar to it in size. The rostrum is subacute, small and rather 

 short ; longer than the eyes, often slightly bifid, with three teeth 

 on the upper edge; it usually has one minute tooth, close to the 

 tip, on the under side, but this may be lacking. Abdominal seg- 

 ments are strongly carinate and sculptured. 



Length of a large adult female, 90 mm ; carapace with rostrum, 

 21.5 mm; rostrum, 5 mm; abdomen, 6.85 mm. One young speci- 

 men, taken by us in 1898, was determined by Miss Rathbun. It 

 agrees well with the description and figures. The specimen 

 recorded as S\ carinata by Rankin was taken in shallow water in 

 Harrington Sound, on white sand. His copied figure represents 

 .S. edwardsii. Otherwise the latter has not been recorded from 

 Bermuda. 



Dr. Rankin stated that in his Bermuda specimen there is one 

 tooth behind the gastric region; the rostrum has four teeth close 

 together on the dorsal edge and none below, which is not the case 

 in S. carinata Bate (=edwardsii Miers), as Dr. Rankin observed. 

 His two specimens had lost their thoracic appendages. According 

 to his description it differs both from ^. dorsalis and S. edwardsii,
