358 A. E. Verrill Decapod Crustacea of Bermuda. 



ginal denticles. But the latter, even when not over s to in" 11 " across 

 the carapace, has the tips of the chela' concave or spoon-like ; the 

 post-orbital tooth is not coalescent with the next, and the front is a 

 little more evidently bilolu-d. 



The original types of this species \\cre from Bermuda (coll. Goode, 

 1877). It was in the collection of J. M. Jones, and has been 

 obtained by nearly all later collectors. We found it abundant in 

 1898 and 1901, at low-tide, associated with the young of several 

 other species. Some specimens taken in April carried eggs, although 

 less than 8 mm long (see Xo. 3280", tig. t, pi. xvi). 



Its range extends from Florida to Maceio, Brazil. (Porto Rico 

 and Maceio, Rathbun.)

FIGURE 19. PLATE XIV, FIGURE 10. 



Carapace very convex longitudinally, nearly straight transversely. 

 Front much deflexed, composed of two lobes, the inner and outer 

 angles alike and evenly rounded. A slight emargination in the 

 coalesced tooth. Second tooth semi-lobate; third and fourth short, 

 pointed, triangular. Carpal groove wanting. Finders evenly den- 

 tate. In the larger cheliped there is a slight tooth on the dactyl, 

 and also one on the manus. Appendages of male abdomen very 

 much like those of herbsti!. 



In the fresh state this species is readily recognized and separated 

 from all other crabs by the color. Carapace, a brilliant purplish 

 blue ; carpus and hand, bluish; proximal upper half of the dactyls 

 of chelipeds, pink ; remainder of fingers, porcelain white ; lower 

 portion of chelipeds and carpal tooth, orange-yellow. (Benedict and 

 Rathbun, abridged.) 



Length of carapace of a large specimen, 28 mm ; width, 42.5 mm . 

 The $ specimen from Bahia (pi. xiv, fig. 9, No. 4028) has the cara- 

 pace 9 mm long, 14 mra wide; front 5 nim ; larger chela 10 nim long, 5 mm
