A. E. Verrill — Decapod Crustacea of Bermuda. 



The type, which is the only specimen known, was caught in a 

 baited fish ti-ap in Harrington Sound, in shallow water, April, 1901, 



The specimen which approaches most nearly to the type of this 

 variety is a cast shell, found on the shore (fig. 15) and of which only 

 the carapace was preserved. 1 have included its measurement with 

 variety obesxs, however, as a matter of convenience, though it differs 

 from that in having larger and more squarrose marginal teeth, of which 

 the second and third are obtusely I'ounded ; and in having a prom- 

 inent and distinctly 4-lobed front, as in tninax, from which it differs, 

 therefore, chiefly in the shorter second and third teeth, and the nar- 

 rower and more rounded carapace. The flanks were convex and the

granulation pretty fine, except on the front. Ratio of length to 

 breadth, 1 :1.4 ; length of carapace SO"'"^ ; breadth 42'"'" ; front 14""°. 

 M americanus (Saus.) = ^. areolatus Kath., figure 16, differs very 

 little from some of the forms of this species. Although it averages 

 slightly narrower, there are specimens of Herbstii (No. 470 in 

 our collection, see table) as narrow as some of those from Brazil, 

 referred to this species by Miss Rathbun (in Coll. Yale Mus.). The 

 lateral marginal teeth are a little less oblique and less concave in 

 front, but in some specimens this distinction fails ; indeed, the teeth 

 of opposite sides of one specimen may sometimes differ considerably 

 in outline, or about as much as the species differ in this particular. 

 But in this form the teeth are more thickened at base above, and are 

 rather more granulous at the edges. The fourth and fifth teeth are 

 more squarrose, and the tips are turned upward. The third tooth 

 often differs but little from the others in size, but its tip bends for- 

 ward and the outer margin is convex ; it is not always as large as
