Geographic Distribution: Cayman Brac, Cayman Islands.

Type Locality: West end of Cayman Brac, Cayman Islands [19° 41.033' N, 79° 53.583' W]

The Common Strophia occurs on the west end of the island of Cay­man Brac, and at a fishing camp on the north side of Little Cayman, also scatteringly about the houses on the west end of this key, but was probably carried to the two latter named places, by the inhabitants, the animals crawling upon their boats, or lumber, etc., and were in this manner transported.

I do not remember ever having seen any species of Land Shell, more abundant [than] this species of Strophia. In the shrubbery that bordered the paths and roads about the west end of Cayman Brac, they were very common, clinging to the base of the bushes, in masses, but their stronghold was the cocoa-nut grove on the south shore of the key, just opposite the few houses at the west end; here they absolutely swarmed in certain spots. Not only was the low herbage covered with them, but they fairly whitened the bases of the stems of the cocoa-nut trees, and often accumulated in such numbers on the small stumps, that they clung one top of another, often three or four deep, and could be gathered by the double handfuls. As the weather was mostly dry, they did not move much, so I could not decide upon what plant they fed, but judging from their numbers, this food plant must have been abundant, and by cultivation of the soil, the Strophias were placed under favorable cir­cumstances for the increase of the species. Through the agency of man, three or four other species had been introduced into this large colony which occupied in all, about half a square mile of country." (Maynard, 1889:23-24)

Type Material: Lectotype, MCZ 076065

Clench (1964:368) designated MCZ 076065 as the lectotype. The other syntype became a paralectotype. The remaining 9,998 specimens have no status as types (Harasewych et al., 2007:379).


Clench (1964:368) regarded this taxon as a synonym of Cerion pannosum (Maynard, 1889). Hummelinck (1980:59) recognized it as a distinct species.
