Shell ovately-fiisiform, spire rather long, conical, with convex sides and short slightly 

 recurved canal. Whorls 7 to 8, upper ones rather convex, last one contracted below the suture, 

 which is distinct and irregularly squamate. Sculpture consisting of broad, rounded, concentric 

 ribs, 8 in number on last whorl, and coarser and finer striae, which make the surface slightly 

 crenulate; this sculpture is crossed by spiral lirae, four in number on penultimate whorl, of 

 which the subsutural is the broadest, these lirae are separated by grooves which have the 

 character of intermediate lirae. Colour orange brown on the lirae, dark red-brown in the interstices. 

 Aperture oval, angular above, peristome rather thick, undulated by the lirae, columellar margin 

 concave. Interior of aperture with rib-like lirae at some distance from the peristome, with a 

 tooth at the entrance of canal ; columellar margin wuth a thick layer of enamel, its basal part 

 with 3 plicae, of which the most basal one is double, its left margin ridge-like, leaving an 

 umbilical slit. Canal short, directed to the left. Interior of aperture yellowish, its margin and 

 canal orange, the margin with brown streaks corresponding to the lirae. 



Alt. 1772, lat. 8Y^; apert. alt. 5Y2, with canal 8Yn, lat. f\. Mill. 



This species is allied to the preceding one, but is easily distinguished by its colour, 

 which is just the reverse of L. turrihts, the lirae being lighter than the interstices, moreover 

 it differs in many details of shape and sculpture. In arrangement of colour it resembles much 

 Peristernia lauta Reeve, which has the same sculpture and distribution of colours, but is more 

 slender and there is no white on the ribs, else the differences seem to me to be of no great 

 importance, if compared with the only specimen of lazcta in my collection, w^hich is however 

 in no excellent condition. I have named the species after iMr. J. C. Melvill, who has made 

 a special study of the genus and has assisted me by comparing the doubtful specimens, and 

 pointed at the differences between the new species and P . latita.
