Ecological and Systematic Notes on Caecidae from St. Croix, U.S. Virgin Islands
Abstract:A survey of the shallow marine fauna at St. Croix, U.S. Virgin Islands, was made in the summers of 1969 and 1970. Sediment samples were collected by diving, and micromollusks were picked from them. The Caecidae were studied from shallow-bay sediments and a quantitative study was made at three slightly deeper stations in and around the coral reefs. Seven species of Caecidae, 268 specimens, were found in 176 cc of sediment from the three stations in deeper water. An eighth species was rare in the area of shallower water.
The eight species, Caecum condylum Moore, C. subvolutum Folin, C. lineicinctum Folin, C. regulare Carpenter, C. textile Folin, C. imbricatum Carpenter, C. (Meioceras) nitidum Stimpson, and C. (M.) cornucopiae (Carpenter), are all poorly known. The first three species do not live in back-reef or lagoonal areas, and so were supposed to be extremely rare. However, these three species comprised 55 per cent of the Caecidae from the three stations in deeper water. They live in an environment that has been little sampled, so have been seldom collected. Distribution for all of the species is tropical, although C. nitidum and C. imbricatum are found in the northern Gulf of Mexico as well.
