GENUS OCYPODE. 71 



which they have just left, and having closed up the en- 

 trance, so that it is undi»tinguishable from the general sur- 

 face, they retire to the bottom to pass the winter in a state 

 of inactivity. 



This species is ligiired by Catesby in such a manner as 

 to leave no doubt as to its identity with the individual 

 here described. In the West Indies, whence his speci- 

 men was obtained, this Ocypode arrives at a size rather 

 more considerable than in this country, but in no other 

 respect, that I know of, does it diifer. The species des- 

 cribed by Mr. Latreille from Mr. Bosc's work, under the 

 name of albicans^ seems to agree in some measure with 

 this, but as he does not refer to Catesby 's figure, I am 

 not prepared to say it is the same; this uncertainty has in- 

 duced me to insert the description in this place, notwith- 

 standing the certainty of its having been noticed before. 



2. O. pugilator. Thorax transverse quadrate, gla- 

 brous, a little straitened behind; one of the hands in the 

 male very small, the other very large. 



Ocypode pugilator? Latreille, Hist. Crust, et Ins. 



Inhabits bay shores and salt marshes. 



Thorax, when closely examined, covered with minute 

 granulse; about one third of the front elongated, deflected 

 and rounded at tip, remaining anterior margin rectilinear, 

 the angles not sallient but acute, andv/ithout sinusbehind 

 on the lateral edge; lower eye-lids regularly dentate; 

 cheeks scabrous; feet almost naked (there are however a 

 few scattering hairs,) somewhat scabrous or rugose; one of 

 the hands remarkably large, longer than the feet, a little 

 granulate, equal above and beneath, fingers nearly straight, 

 with very small tubcrculiitc tcctb, tlmmb distant from
