new Species o/Pleurotomicl£e. 491 



Hah. Australia. 



This species has a close relationship to P. violacea, Hinds, 

 from which it differs, however, in colour, the number of cari- 

 nations, and the more produced spire. It is still more nearly 

 allied to P. vallata, Gould, from which it differs only in size 

 and the presence of only one plication on the columella, 

 whereas P. vallata possesses two. It may be merely the adult 

 of the latter species.

 10, primi 2 laeves, politi, coeteri planiusculi, infra suturam tuber- 

 culoriim parvorum serie duplici, infra eam liris spiralibus 1-2 

 gracilibus, infra quas circa medium tuberculorum majorum serie 

 duplici secunda, et infra banc liris 1-2 ex nodulis jiarvis factis
