posterior edge more convex ; the coalesced first and second teeth 

 have the two cusps prominent and nearly equal in height ; the second 

 is obtuse and broader. The front is somewhat produced and is 

 distinctly 4-lobed or sinuous ; the edge is often upturned and granu- 

 lated in the adults.

The carpus of the chelipeds is granulated, but nearly smooth to 

 the naked eye, usually with a slight undulation or depression in 

 place of the distal groove, bht in some this is entirely obsolete. 

 The carapace is somewhat uneven, with the areolation not much 

 raised but well marked ; slight transverse rugse are usually pres- 

 ent ; the surface is usually finely punctate and granulate, but in 

 some examples it is transversely rugose and more granulose. The 

 color is variable, but usually is yellowish or olive-yellow, mottled 

 more or less thickly with red or red-brown. The fingers are blackish, 

 varying to dark liver-brown, and below, the dark color is apt to 

 extend backward on the raanus, a little beyond the base of the 

 dactyl us. 



A specimen (No. 4016) taken at Long Bird Island, April 19, 1901, 

 in life had the carapace curiously variegated with gray, white, and 

 blackish brown, and with patches of orange in the middle, near the 

 front edge. Chelipeds thickly spotted and specked with bluish gray, 

 and with a patch of orange on the back of the carpus and chela. 



The ratio of length to breadth of the carapace, accprding to the 

 measurements of Prof. S. I. Smith,* varies from 1:1.33 to 1:1.48.
