and reflected, small narrow canal at the upper part of the peris- 

 tome on the inner side ; columellar margin with wide slit, not 

 extending through the margin but running spirally inside of the 

 aperture ; acute keel round the perforation. 



Length 13f, breadth 6^ lines, large specimens. 

 Length 10 J, breadth 5\ lines, small specimens. 

 Hab. New Guinea. (Captain Hovell.) 



This species was first taken for pupina grandis, Forbes, my 

 having two and Dr. Cox two specimens of the original pupina 

 grandis, collected first by the late Mr. John Macgillivray, Natu- 

 ralist of H. M. S. Rattlesnake, at the Louisade Islands ; this 

 species is quite distinct, the most distinguishing character is at 

 the columellar only having a slit and not the ear-shaped auricle 

 of grandis ; of some hundreds that I have seen, not one approaches 

 to grandis. I have named it after George French Angas, F.L.S., 

 C.M.Z.S., to whom I am under great obligation in comparing 

 Australian and other shells for me in the British Museum. 



* 10. — Epidkomus Bednalli.

 times brown, aperture ovately oblong, smooth within, collumella

Hab. Guichen Bay, South Australia. (W. Bednall.) 



This species approaches near to Epidromus Brazieri, Angas, and 

 Epidomus Qoxi, Brazier, two species found in New South Wales. 

 Named after its discoverer, Mr. William Bednall, an enthusiastic 

 and intelligent conchologist, late of Adelaide, now of Port Darwin
