angular linos and spots of a chesnut colour; spire acuminated, 

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

 last posteriorly tubercidated, 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 tliree to five rather irregular folds. 



An extremely rare species, of wliich the finest specimen we 

 have seen, from which om- figm-e is taken, is in Mr. Norris's col-

Tliis volute, pubhshed in 1836 by Broderip imder the name of 

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

 oifiisiformis, a name wliich had been given by Swainson to a very 

 distinct species in the Bhgh Catalogue, and to Avliich species Kiener 

 has given a new name in a most absurd manner, Yoluta Beckii 

 occasionally reaches twelve inches in length.
