minent, with central depression, in some individuals subacute with subdenti- 

 culate edges; outer angle of eye acute but without spine, from it a distinct 

 border to carapax runs back for two-thirds of its length ; exterior antenna 

 with filament about the length of carapax or a little shorter. 



Anterior feet subequal, in some individuals the right, in others the left is 

 the larger, carpus short, about half the length of body, and a little longef 

 than broad, with a projecting lobe at base of inner edge, this edge without 

 spines, outer edge with a slightly raised border, and a single spine at articu- 

 lation with hand; hand about as long as carapax, subtriangular in outline, 

 lower edge ciliate, finger and thumb with opposing edges nearly straight and 

 without teeth, the tip of former incurved and folding within the slightly in- 

 curved tip of latter. Four pair of posterior feet, without spines, and ciliate 

 on the edges of the different segments. 



Color. In the recent specimen the carapax and anterior feet are ocellate 

 with white spots on a reddish ground, which is frequently deeper around the 

 spots; posterior part of carapax and abdomen with alternating whitish and 

 reddish longitudinal bands, posterior feet with transverse reddish bands, in 

 which the ocelli may frequently be perceived. All these markings are less 

 distinct in the dry specimen. 



Geo. Distr. — Coast of South Carolina. Readily distinguished by its tri- 

 fid front and ocellate markings, and short carpus. 



Remarks.— Say's description of the third species in the manuscript notes 

 above mentioned applies to this species.
