angular lines and spots of a chesnut colonr; spire acuminated, 

 rather short, with a small papillary apex; volutions 5|, the two 

 last posteriorly tuberculated, the last very large ; aperture large, 

 oblong, somewhat acuminated posteriorly, outer lip with a thick- 

 ened edge, inner lip rather thick, spread over the last volution ; 

 columella with from three to five rather irregular folds. 



An extremely rare species, of which the finest specimen we 

 have seen, from M'hich our figure is taken, is in Mr. Norris's col- 

 celtion. Mr. Cuming and the British Museum also possess the 

 species.

This volute, published in 1836 by Broderip under the name of 

 Voluta Beckii, has since been figured by Kiener under the name 

 oifusiformis, a name which had been given by Swainson to a very 

 distinct species in the Bligh Catalogue, and to which species Kiener 

 has given a new name in a most absurd manner. Voluta Beckii 

 occasionally reaches twelve inches in length.
