 perne versus labrum tuberculo elongate parvo munita, ad basim trans- 

 versim 2-3-plicata ; labrum album, fortiter incrassatum, margine tenui, 

 intus liris brevibus circiter 9 baud ad marginem productis armatum ;

The colour of this species is somewhat variable. There are tvro 

 varieties, a dark and a pale one. The former is whitish, with nu- 

 merous reddish brown blotches or irregular stripes, and with the 

 spiral lines of the same colour, five or six on the penultimate 

 whorl and about fourteen on the last, the four or five lowest ones 

 running in the striae around the base. The paler variety is yel- 

 lowish, with very pale brown irregular blotches and stripes. In 

 all specimens the upper part of the last three whorls at the suture 

 is slightly crenulated and spotted with dark reddish brown and 

 white, and the three or four apical volutions are of a uniform 

 brown colour. iV. gaudiosa, of Hinds, is its nearest ally, from 

 which it may be distinguished by its smaller size, narrower form, 

 and difference of coloration. It is with pleasure that I join to this 

 species the name of my friend Mr. F. Marrat, of Liverpool, who is 

 now engaged upon a monograph of this genus.
