Cerion niteloides Dall, 1896
Cerion (Maynardia) niteloides
Dall, 1896:15, pl. 1, fig. 2; Pilsbry & Vanatta, 1899:475; Clench, 1961:254.
Dall's remarks: "This species externally much resembles Cerion (Maynardia) nitela Maynard , which is a species native to the west end of Little Cayman island in the Caribbean Sea on the south side of Cuba. As the species of Cerion are very limited in their distribution the wide separation of the two localities raises a suspicion of distinctness, notwithstanding their superficial likeness, and this suspicion is measurably confirmed by the following differences: C. nitela has a larger axis and a considerably larger and perforate umbilicus; its parietal tooth is more elevated and less elongated, the pillar tooth slightly more elevated, and its inward prolongationdecidedly more feeble, lastly its aperture is narrower, more horse-shoe shaped and less rotund than C. niteloides. The apex is decidedly more pointed in the specimens of C. nitela before me as well as in Maynard's figures, but this character is variable in some of the species.
"It may be noted here that the use of the shells by hermit crabs tend to wear away the pillar and denticulations, so that persons working over these shells should make sure, when estimating their characters, that the shell was tenanted by its architect when collected, otherwise blunders are pretty sure to be made."
