131. spilota (Rav. MS.) n. sp. 
Shell ovate, polished, ashy-white with about 40 round orange-colored 
spots nearly 1 mm. in diameter; spire sunken, showing a little more 
than three volutions; aperture narrow, curved, chanelled above and 
deeply notched below; outer lip white, thickened within, but perfectly 
smooth, showing no trace of denticulation, developed into a well-marked 
varix which extends beyond the spire; inner lip heavily callous, with a 
conspicuous lump above, and eight strong, transverse plaits separated 
by wide deep grooves, the lower one twisted downwards, and the upper 
one obsolete. Length, 15 mm. Breadth, 10 mm. 
This very distinct and beautiful shell was first mentioned in 
Professor Gibbes’ List in Tuomey’s Geology of South Carolina 
with the notation “not yet described.”’ Strangely enough it is 
not named in either of Dr. Ravenel’s catalogs, but Kurtz lists 
it with the reference ‘‘Gibbes’ Cat. N. & 8. C.’ Redfield, in his 
catalog of the family Marginellidae, says: ‘“M. spilota Ravenel, 
of Catalogues, is an unpublished, hence unknown species.”” For- 
tunately, I have discovered the original specimen in the Ravenel 
collection, now in the Charleston Museum,? with two interest- 
ing labels, one reading simply ‘Marginella, Persicula, spilota, 
Rav. Beach, Sulliv. Island, So. Carol.,” the other, “‘ Marginella 
spilota Rav. Sullivan’s Island. In thirty years I have found 
two specimens exactly alike. One I sent to Dr. Gould for exami- 
nation and he gave it to Mr. Agassiz to return to me— and I 
have ” the last word is illegible, and a line has been run 
through the name Marginella. The species belongs to the section 
Persicula.
