wide, sensibly notched. 



P. Mtlonyena. Shell pyriform, turgidly ventriooae, cccrulescent, 

 glaucous, or rufous, banded with white; the whorls channelled at 



the sutures; the last sometimes unarmed, but more frequently muri-

 transversely sulcated, cinerespent- white; the spire rather prominent; 

 the canal short, widely umbilicated ; muriculated on the buck with 

 subechinato elevated furrows ; outer lip striated within, and its margin 

 denticulated. 



Pyrulte have been found on mud, sandy mud, and sand, at depths 

 ranging from the surface to nine fathoms. 



There are 39 recent species and 30 fossil. The recent are found in 

 the West Indies, Ceylon, Australia, China, and West America. The 

 fossil are found in the Neocomian beds of Europe, India, and Chile. 



Fateiolaria (Lam.). Shell fusiform, not very thick, rather convex 

 in the middle, with a moderate spire ; aperture oval ; canal rather 

 long; sometimes slightly bent; right lip trenchant, often wrinkled 

 internally ; coluuiellar lip with some very oblique plaits. Operculum 

 horny.

F. Jttantcntota. Shell elongated, fusiform, turreted, transversely 

 sulcated, white, painted with longitudinal orange-red stripes ; middle 

 of the whorls subangulated, and the whorls themselves crowned with 

 short and compressed tubercles ; the canal rather long; the outer lip 

 striated within. It is found in the East Indian seas.
