is of a claret brown which modifies the external color by transmitted 
light; spiral sculpture, a strong broad thread close to the inconspicuous 
suture, separated by a rather broad spirally striated fasciole from a series 
of two (on the early) to four (on the last whorl) rather strong, spiral 
smooth rounded threads which are succeeded anteriorly by eight or ten 
similar spiral threads which, on the base, are nodulous and smoother 
on the anterior end of the shell; these are crossed by strie of growth and 
partly by nine to eleven stout short ribs, beginning at the fasciole and 
ceasing just beyond the periphery ; the most prominent part of these 
are white and the threads which pass over them become yellowish or 
white and stronger than they are between the ribs ; the little nodules 
on the basal threads have a tendency to whiten as does also the sutural 
thread; this is, however, hardly noticeable without a lens; canal short, 
wide, straight, notch moderately wide, not deep; aperture rather nar- 
row, smooth and claret brown, outer lip not much curved out; lon. of 
shell, 7.5; of last whorl, 4.0; of aperture, 2.75; lat. of shell, 2.70™™. 
Habitat—Key West; rare on the reefs at low water. This recalls 
D. albomaculata D’Orbigny, but is more slender, and differs in the 
details of sculpture. ‘Tne last whorl of the specimen figured shows an 
interruption of the sculpture due to a fracture. 
Drillia limonitella n.s. (Plate X, Fig. 10.) 
Shell small, thin, translucent, lemon yellow; in fresh specimens the 
dried animal matter shows through and gives the upper whorls a livid 
ashy or greenish tinge; there is also a reddish tinge on the columella; 
the young shells have much the appearance of a Bela, but doubtless 
develop a thickened outer lip and more pronounced noteh with 
maturity, since several nearly mature ones show indications of it. 
Whorls eight or nine, turrited, angulated by the ribs on the periphery, 
with a small nearly smooth nucleus, and sharply sculptured subsequent 
surface; spiral sculpture of numerous sharp threads, quite fine, and 
extending over the whole shell; two stronger closely adjacent threads 
at the hardly visible suture; transverse sculpture of strongly marked 
lines of growth, and about a dozen uniform, narrow, sharply elevated 
riblets, convex anteriorly, extending from suture to suture, and nodu- 
lated with an elongated nodule at the peripheral angle ; fasciole faintly 
marked, notch distinct, canal short, straight, aperture rather narrow; 
lon. of shell, 6.75; of last whorl, 3.75; of aperture, 2.5; max. lat. of 
shell, 2.75™™. 
Habtiat.—Cedar Keys, on mud flats between tides. This resembles 
a miniature M. cerina K. & S8., but is differently and much more 
sharply sculptured. 
Clathurella jewettii Stearns. ‘ 
Cedar Keys, on ‘“ coon oysters.” 
Conus stearnsii Conrad. 
Sarasota Bay, near low water, abundant. This is probably only an 
immature stage of C. floridana Gabb.
