“A single living specimen of this beautiful little mollusk re- 
cently collected by Miss Ida M. Shepard, at Ballast Point, San 
Diego Bay, and which she kindly brought to me for examination, 
enabled me to make the following note on the animal. 
‘When the animal is fully extended, the mantle lobes com- 
pletely envolop the shell. The lobes are of a brownish flesh-color, 
thickly though not closely crowded with mammillated tubercles, 
about thirty-five on each side, flecked and frosted with whitish 
specks. The tubercles vary some in size and form, the larger ones 
being rounded and broad at the base, while the smaller ones are 
narrower and more conical. The nipple-like processes that rise 
from their summits vary in number from 1 to 4 on each tubercle, 
their tips being also frosted with whitish specks. The spaces be- 
tween the tubercles are a shade darker than other portions of the 
mantle, and peppered over with irregular black specks. The edges 
of the mantle lobes that meet on the summit of the shell are light- 
er in color than other portions of the mantle, and are also covered 
with black specks like those between the tubercles. 
‘“‘When the animal is in motion the proboscis extends forward 
like the bowsprit of a boat; it is about % an inch long, a shade 
or two lighter than the mantles, flecked with whitish specks like 
those on the tubercles, with its end slightly expanded and edged 
with white. Two slender tentacles about 5-16 of an inch long 
when fully extended protrude from the head near the base of the 
proboscis, each one bearing a black piercing eye, about midway 
between their tips and the head of the animal. 
“The foot is about as broad as the shell, truncated in front 
and roundly pointed behind, when the animal is in motion. The 
front of the foot is marked beneath by a very fine transverse dark 
line, which perhaps serves to define the front edge of the sole. 
The sole is lighter colored than other portions of the animal that 
are exposed outside of the shell, and is beautifully and profusely 
flecked with very small whitish dots. 
“The animal was slow in its movements, its motion being a 
continuous glide around the vessel in which it was confined, but 
most of the time it remained stationary at the edge of the water, 
as if waiting for the tide to come in, or a chance to escape.’’ 
3050 Conus californicus Hinds. 
“The body of this mollusk is whitish in color, and profusely 
dotted over with black specks that frequently coalesce near the 
margin of the mantle. When the animal is in motion the foot 
extends about 4 of an inch beyond the anterior and posterior 
ends of the shell. It is truncated in front and bluntly pointed be- 
hind. The sole is white and sparsely sprinkled with black specks. 
The motion of the animal is a constant glide. The proboscis is 
black, and about % an inch long when fully extended, and seems 
to be a specialized portion of the animal’s mantle, rolled together 
with the lower edges in contact but not joined. It curves over 
and above the back of the shell, as the animal moves forward. 
Two small tentacles, of a dark color, each 5 mm. long, protrude 
from the head near the base of the proboscis, bearing two small 
keen eyes, which are situated about half way between the tips and 
base of the tentacles. 
The operculum is horn-color and claw-shaped, a portion of the
