C. PUNCTULATUM Martyn. PI. 65, fig. 75. 



Shell conoidal, imperforate, solid, yellowish or light fawn-colored, 

 unicolored or dotted on the spirals with dark brown ; the granules 

 often white by rubbing of the cuticle. Surface covered with narrow 

 spiral closely and conspicuously beaded ridges, numbering 8-12 on 

 the penultimate whorl, sometimes equal in size, sometimes alternately 

 larger and smaller ; on the next earlier (antepenultimate) whorl 

 there are about 7, and still earlier whorls have 3 beaded carinse ; 

 the interstices are obliquely striate. The spire is a little concave in 

 outline toward the apex ; apex acute, minute ; sutures impressed. 

 Whorls about 8 or 9, convex, the last rounded at the periphery. 

 Aperture oblique, rhomboidal, pearly within, and showing folds in 

 the macre corresponding with the line outside ; columella arcuate, 

 pearly, not tubercled below. Alt. 36, diam. 36 mill.

The present species is very similar at first sight to Turbo (Modelia) 

 granosus Martyn ; that species however is shorter in the spire, has 

 a broader columella, and generally more separated rows of granules. 

 The latter, in this form, vary considerably in degree of coarseness. 

 The spire is shorter than in the following species, which is, however, 

 very closely allied. 



C. PELLUCIDUM Valenciennes. Vol. X, PI. 41, fig. 36. 



Shell conical, imperforate, solid, yellowish with a few brown 

 obliquely longitudinal streaks, and closely minutely dotted with 

 brown and white on the numerous closely beaded lirse which en- 

 circle the whorls. These lirse number about 8-10 on the penulti- 

 mate whorl, and the same number on the last above the periphery, 

 but owing to the frequent intercalation of liruke between them, the 

 number is subject to variation. Just at or just below the periphery
