1HE GRAPSOID CBABS OF AMERICA. 



195 



tooth is directed forward, with the tip bent 

 inward, its outer margin is mostly straight. 

 Lateral teeth of carapace 2, similar, second a 

 little smaller, both sharp-pointed, and with 

 convex outer and concave inner margin. 

 Lower margin of orbit oblique, line of in- 

 ner lobe in advance of that of outer lobe, 

 outer lobe slightly convex, inner lobe bi- 

 lobed, outer portion rounded, inner portion 

 a small acute tooth; inner lobe little obscured 

 by the pterygostomian lobe, which is some- 

 what bent down and is triangular with a 

 sharp tip, reaching just as far forward as 

 inner angle of orbit. 



Chelipeds in both sexes little unequal, right 

 manus about twice as wide as left. 



Ambulatory legs short and broad, a similar, 

 triangular, sharp anterior tooth on the merus 

 joints, the first one narrowest, the third lower 

 than the second; posterior distal tooth of 

 merus sharp; lobes of carpus prominent, the 

 distal one of second and third legs acute; 

 propodus of those legs widening greatly from 

 proximal to distal end; dactyli wide, posterior 

 margin sinuous. 



Affinity. On the whole, this species ap- 

 proaches nearest Cymopolia affinis, which has 

 similar teeth on the carapace, but has not the 

 large flat, triangular teeth of the merus of 

 the legs. 



Measurements. Male (station xxx, Blake), 

 greatest length of carapace 9.5, width of same 

 10 mm.; female holotype, greatest length of 

 carapace 9.5, width of same 10.7, length of 

 second leg 18 mm.; female (Yucatan Bank), 

 greatest length of carapace 15.4, width of same 

 17.3 mm. 



Range. Off Cape Hatteras, North Caro- 

 lina; off Yucatan, Mexico; off Cape Frio,
