I'm looking for information on the natural histories/life habits and ranges
of Tricolia affinis and Cerithium litteratum.

Here is why:  I've got a site in St. Croix, USVI where I resampled the same
transect as a previous study (1980) in 2002.  At the time of original
sampling, Cerithium litteratum was highly abundant.  During resampling,
Cerithium litteratums was absent and the population of Tricolia had
increased dramatically.  This is recorded in the shell assemblage despite
time-averaging.

I'm working on finishing an article on this and am interested in literature
or other sources of info on these two taxa and on the current taxonomy of
Eulithidium (used to be Tricolia).  I'm currently using Abbot 1974 and
Redfern 2001 in conjunction but they don't include much in the way of
habitat/environmental prefs (aside from seagrass...).

Thanks.
