Our specimens being old, witli the sculpture eroded, we are 

 unable to determine confidently what the species is, it being 

 unfortunately the custom in this genus and in Chama to describe 

 and figure little more than those exterior characters which ar^ 

 very rarely found in perfection. On6 of the most permanent 

 characters of this species is the broad deep red purple finely 

 wrinkled limb of the otherwise white interior. 



Station. — Unknown.
