 Geological Survey Collection, and the recent examination has necessitated some addition 

 to the description given by my old colleague. 



Specific Cliaraciers. — Smaller form than T. loudonensis, relatively wider carapace 

 and thinner tail. Integuments slightly pitted or wrinkled. The longitudinal keels are

 median and two lateral ones, are continued as longitudinal ridges on all the tail 

 .segments, and the last segment and the telson are considerably ornamented. 



General Description. — Tliis is one of the most beautiful species of this group, and
