  O.D.  Shell small, narrowly elongate, almost tubular in outline, yet
somewhat flattened in appearance; Terminals broad, squarish, posteriorly,
somewhat less so anteriorly; terminal tips, shell margins solidly, thickly
calloused, though only barely keeled posteriorly; dorsum smooth, glossy,
transversely keeled sub-centrally, with a large, rounded ridge, shell tapering
gradually to either end from a sharply upraised outer keel; keel continuous
from outer lip margin, over dorsum, across base, becoming obscure on
columella; base smooth, glossy, narrowly ovate; gently curved aperture without
special character; ventral surface of outer lip smooth, glossy, rounded from
margin to aperture, without dentition; dorsum deep rose, with remainder of
shell, terminal beak margins, base and outer lip milk white, transverse dorsal
keel paler rose. Type locality Offshore coral formation at Sombrero Reef,
Marathon, Vaca Key, Florida Keys. The animal was found in 5 feet of water
living on a purple sea fan. Holotype USNM 710912,
 Discussion: The shell of Cyphoma sedlaki perhaps most closely resembles that
of C. signatum Pilsbry & McGinty, 1939, because of the ventral aspect of the
shell. C. sedlaki differs by being smaller, more flattened, with less heavily
calloused terminal beaks, whose callus thickening is much less upraised, more
indistinct. The shell also differs in having a somewhat uneven longitudinal
construction of the outer lip; the shell color and combination of
colorslikewise are different, with an unusual pattern on the living animal's
mantle and foot.  ETC.

            Hope this helps, Since this is not in American Seashells, I went
ahead and posted it to the whole list. in case anyone wanted to add it to
their Caribbean fauna list.
