" Of this peculiar sinistral heliciform Bulimus a solitary 

 specimen, much weathered but perfect, was found by Major 

 Beddome. It is evidently a coloured shell but only traces of the 

 epidermis remaining. It is allied to B. albizonatus, Hv., and 

 B. intermedius, Pfr., of Ceylon, but is sinistral and has a shorter, 

 more conical form." {Blanford.) 



A specimen in the Theobald collection in the British Museum, 

 probably the one figured in Conch. Ind., although also rather 

 weathered, has the periostracum intact on some parts of the last 

 whorl and exhibits traces of extremely minute spiral sculpture, a 

 feature also observed in other species of Beddomea. The peri- 

 pheral keel is ornamented with a narrow pale brown band which 

 can be traced some distance up the spire, and the protocouch is 

 pale fuscous. It measures : length 19, diam. 14-5 mm.
