The body is widest in the middle, but is much narrower at the anterior than at the 

 posterior extremity. The last pair of feet are scarcely longer than the preceding. This 

 species closely resembles G. rubens, Say, and may possibly prove identical with it, as the 

 descriptions of that form are as nsnal quite meagre. Length, 1 inch.
