Coelotrochus Chathamensis
''Coelotrochus chathamensis'' is a species of small sea snail, a marine gastropod mollusc in the family Trochidae, the top snails or top shells. Description The length of the shell varies between eight mm and 10 mm. The small shell has a conical shape, the sides are straight or slightly convex.. The angle of the spire is 70°. The five, rarely six, whorls are flat with an elevated upper edge, and, together with the base, spirally striated. The pointed protoconch is regularly conical, and consists of about two whorls. These are not marked off from the succeeding whorl. This one is, smooth, with two or three spiral red bands. The last two whorls increase rapidly in size. They are flat to slightly convex above, concave below before reaching the strong and prominent cingulum. The body whorl has a distinct peripheric keel. The sculpture consists of five to six low spiral threads, the lower and upper margins much elevated, especially the former. They are crossed by broad nod ...
