Conrad's specimens are full grown while Lea's are all young. 

 In Lea's book the name O. semilunata occurs one page earlier 

 than O. alabamiensis and hence might be used in preference 

 to the latter; yet it is applied to a distorted specimen and 

 besides, O. alabamiensis is now in common use. The type 

 specimen is not so thick as Lea's figure indicates. This 

 species is remarkable for its horn-like epidermal coating 

 marked hy fine radiating striae.
