 Through an evident oversight, Jay gave to this shell the name 

 Bulimus ustulatus on page 119 of his Catalogue, forgetting Bulimus 

 ustulatus Sowerby published in 1833 in Conchological Illustrations, 

 figure 42, which Jay quotes on page 57 of his Catalogue, where he 

 describes his shell as "1919b Bulimus ustulatus Sowb., Conch. Illust., 

 fig. 42." The fact that most authors consider Jay's name a synonym 

 of Cochlostyla chrysalidiformis (Sowerby) has been responsible for 

 its not having been rechristened. I therefore have renamed it Cochlo- 

 styla (Chrysallis) jayi. 



Shell large, pupiform, cylindro-conic, rather rough. The early 

 whorls are flesh-color with a narrow brownish zone at the summit. 

 This gradually changes through straw-color to bright chestnut-brown 

 ground color and is crossed by hydrophanous axial zigzag bands of 

 straw-color. This coloration also holds good on the base. The 

 aperture is bluish white within, and the peristome and columella are 

 livid with a purplish tinge. The parietal callus is thin and of the same 

 color as the peristome. Nuclear whorls 2.8, well rounded, smooth. 

 The postnuclear whorls are slightly rounded, appressed at the summit, 

 and marked by retractively curved irregular lines of growth, which 

 give to the surface a somewhat rough appearance, almost that of
