ground-colour of the shell." There seems from the drawing to be 

 but a single anterior moderately distant lateral tooth, and no 

 ej-terual appearance of rays in the front of the shell. The sculpture 

 must indeed be minute, to have escaped the attention (as it has) 

 of our very accurate artist.

The specimens closely resemble the young of the Punicea group, 

 but both locaHty and dentition ai-e adverse to tliis conclusion. 

 They appear, however to be scarcely adult.

The representation of the species in Delessert's magnificent 

 folio, enables me to refer this shell to the present division. I am 

 unable, however, to add a more lengthened description than the 

 verv meagre outline furnished in the ' Animaux sans vertebres '.
