Panopeus depressus is readily distinguished from dissimilis by having 

 the male abdomen composed of five segments instead of six. It is dis- 

 tinguished from all other species by the flattened carapace with trans- 

 verse granulate rugie, the nearly straight front, and the prominent 

 semi-spoon-shaped fingers of the small hand, and occasionally of the 

 large, in connection with the black or dark brown color of the fingers, 

 the color running up on the hand far behind the gape of the claw. 



Margin of second segment of male abdomen concave. Coxjie of fifth 

 pair of feet in contact with third segment. 



Length of carapace in large si)ecimen, 14 millimetres; width, 19.5 

 millimetres.
