14. Cancellaria caperata, spec. nov. Plate ix., fig. 7.

 one and a half smooth subglobose turns. 



Whorls three and a half, excluding pullus, convex, sloping 

 more rapidly to the posterior suture. Ornamented with rounded, 

 depressed cost», and with spiral threads in front of the angula- 

 tion, forming crenate-nodosities at the intersection, conspicuously 

 so on the posterior thread ; the whole surface finely transversely 

 striated ; penultimate whorl with three strong spiral threads and 

 a slender one at the anterior suture. Last w^horl with about ten 

 spiral linv, cost» inconspicuous. Aperture oblong, rounded at

15. Cancellaria capillata, spec. nov. Plate x., fig. to. 



Shell small, stout, elongate-oval, apex obtuse; w-horls six, con- 

 vex, lirate and slenderly costated. The spiral lirse increase in 

 number from four on the first ordinary whorl to ten on the 

 penultimate whorl ; and produce slight nodose-crenulations on
