The second, fourth, sixth and eighth costals are narrow 

 above and wider below ; the first, third, fifth, and seventh are 

 wide above and narrow below. 



As only the central portion of the plastron is preserved, but 

 few characters can be gleaned from it. The species seems to 

 be at least fairly common, both in the beds along the Muddy 

 Creek and also along Raw Hide Creek, no less than iive 

 specimens having been found.
