Professor Tate remarks that this is the antipodean analogue of 

 C. erulsa, Solander, from Barton, and that it differs "only by its 

 much finer ornament, and by the lirte within the outer lip." No 

 doubt there is a close I'esemblance between the two species, but a 

 study of the protoconch is sufficient to separate them immediately. 

 The Australian shell commences with a relatively large protoconch, 

 the earlier portion of which is obtuse and even slightly inflated, 

 and is composed of only one and a half turns ; the Bartonian .shell, 

 on the other hand, has a somewhat pyramidal protoconch com- 

 posed of from two and a half to three turns, the earlier portion is 

 not oblique, and the whole is regularly coiled. There must be some 

 error respecting the lirae alluded to : both the Australian and 

 European shells possess these within the outer lip, typical examples 

 of C, evulsa from Barton having them especially prominent opposite 

 the varices. The Australian shell is thinner. 



Bimensmis. — Length 14 mm. ; breadth 8 mm. ; length of 

 aperture 5'5 mm. 



Form, and Loc. — Eocene : Victoria. 



48052. Specimens much more tumid than the type ; this has 

 considerable analogy with C. evulsa ; from Schnapper Point.
