This is a very common species, but small and easily overlooked. 

 In life it is quite variable in colors. Many specimens were varie- 

 gated with lighter and danker gray ; others are olive-green or olive- 

 brown, mottled with paler ; some have red-brown patches, other 

 were finel}^ mottled with brown and gray on a whitish ground-color, 

 so as to very closely imitate the color of the sand, etc. of its environ- 

 ment. A few were plain bright red-brown. The colors appear to 

 be highly protective in most cases. The fingers are somewhat vari- 

 able in color, but are usually pale, sometimes with a smoky brown 

 tinge, especially on the proximal half. 



The following is condensed from the detailed original description: 



Carapace distinctly areolated, posteriorly as well as anteriorly ; 

 areolations with transverse lines and occasional small clusters of 

 granules. Front much produced, rather deeply cleft in the center, 

 the cleft rounding out into the median lobes which are produced at 

 this point ; outer angles of the front not produced in some speci- 

 mens, and slightl}^ in others ; edge of front oblique, thickened, 

 denselj^ granulate, and showing a slight marginal groove; two fis- 

 sures on the upper orbital margin. 



First and second [post-orbital] teeth of the antero-lateral margin 

 flat and thin ; third and fourth thickened, with anterior margins 

 concave and hollowed. The sulcus of the coalesced tooth varies 

 greatly with the specimen. Second [post-orbital] tooth the largest, 

 separated from the first by a wide and deep notch ; its margin 

 straight, pointing slightly forward and not at all hooked. The third 

 tooth is much narrower than the second, and its posterior margin 

 curves gradually backward to the bottom of the notch; fourth tooth 

 much the smallest, sharp pointed, and directed nearly perpendicular 

 to the median line. 



Outline of male abdomen slightly concave. First and third seg- 

 ments comparatively narrow and of about equal width. Second
