Variations. — Largo male (24515) 

 more hairy than other specimens. 

 Middle supraorbital lobe varj'ing 

 from subtruncate in large specimens 

 through obtuse subtri angular in me- 

 dium specimens to acute subtriangular 

 in the smallest specimen. "While the 

 outer margin of outer orbital lobe is 

 ahva3's convex, it may sometimes be 

 partially straight or even a little con- 

 cave. The tooth on merus of legs 2 

 and 3, although usually obtuse, is 

 acute on right side only of a single 

 specimen. The anterior distal lobe of 

 carpus of the same leg varies in 

 acuteness. 



Color. — From a newly preserved 

 specimen. Ambulatory legs banded 

 with reddish orange-brown on a yel- 

 lowish ground; third leg faintly 

 banded, mostly yellowish. Carapace 

 dull light brown mottled with orange 

 brown. Chelipeds same uniform color 

 as leg bands. 



measurements. — ^ISIale (24515), 

 greatest length of carapace 12.7, width 

 of same 14.8, length of second leg 24.4 

 mm.; female (49142), greatest length 

 of carapace 9.9, width of same 11 mm. 



Uanrje. — Charlotte Harbor to Mi- 

 ami, Florida; St. Thomas; St. Croix; 

 Barbados. 20-117 fathoms. 



Material examined. — Sec table. 



Remarks. — I think that the type of 

 agassizi is a j'oung specimen of affinis; 

 compare, for example, Edwards and 

 Bouvier's plate 8, figure 10, with the 

 same leg on figure 1 ; in their plate 7, 

 figure G, the projection at inner angle 

 of orbit appears exaggerated, while in 

 plate 8, figure C, the edge of the 

 pterygostomian lobe is truncated be- 

 cause bent down away from the hori- 

 zontal.
