There is little doubt of this species being the true 

 D. varieyatum of Lamarck, who notifies the locality 

 New Holland, from whence a magnificent series may be 

 seen in the British JIuseum, including specimens even 

 larger than any to be found of the D. yalea. They were 

 collected by Mr-. Jukes during liis recent expedition to 

 that country, and are from Torres Straits. 



The B. ChiueiKe, which Dr. PivQippi refers to Lamarck's 

 B. variegatum, is no doubt the Chinese analogue of this 

 species ; its plan of gro\rth and style of colouring are the 



same, and it differs only in being more globose and of 

 lighter structm-e ; stUl it is not Lamarck's type, and when 

 named by Chemnitz Bucciuum Australe seu CJdnense, he 

 may have had specimens from both localities before him.

The ribbed Tun. Shell ovately oblong, ventrieose, 

 scarcely umbilicated, whorls seven in number, flatly 

 depressed and slightly channelled round the upper 

 part, transversely ribbed, ribs thirteen to fourteen in 

 number, rather prominent, distant, interstices broad, 

 concave, smooth ; aperture oblong, lip fimbriated and

Hab. PliOippine Islands ; Cuming. 



This bold species is amply distinguished from the 

 B.fimiafum, by the prominent and remote development 

 nf the ribs, and absence of banded colourini;.
