Represented only by a single specimen and its reverse, showing the 

 under surface of the body, from which the appendages have been torn. It 

 closely resembles in size, form, and the relation of the parts P. gi-ossa 

 (Fabr.), but differs from it in the character of the under surface of the body, 

 which in the fossil species is very minutely and very faintly punctulate, 

 and the posterior edges of the segments are not I'aised.
