evident on one cheliped and entirely lacking on the other, but it is 

 always, when present, ill-defined. The marginal teeth have nearly 

 the same outlines ; the front edge is a little less concave, and conse- 

 quently the tips are not so much incurved, but this character is also 

 variable in both species. The marginal teeth are, however, thicker 

 vertically. The front is a little more prominent in the middle, and 

 the median notch is less distinct. The specimen figured (No. 3021) 

 was identified and labelled as this species by Miss Rathbun, several 

 years ago. It was collected at Hamilton by Dr. C. Hartt Merriara, 

 April, 1881, and carried eggs. The ratio of length to breadth is

This species is not common in Bermuda, and is not contained in 

 most of the collections. It was first obtained by Dr. Merriam, in 

 1881 (see above). 



Its range extends from S. Carolina through the West Indies to 

 Pernambuco, Brazil.

The following description is that of a young specimen : 

 Carapace convex, with rather well-marked areolets. Front very 

 little produced, nearly straight, thin, with a line of granules on the 

 edge, giving it a minutely denticulate appearance. Antero-lateral 

 teeth sharp, the posterior three hooked forward. Sinus between the 

 external angle of the orbit and the first tooth deep. External hiatus 

 of orbit a large V-shaped opening. Subhepatic tubercle small but
