lower or sharp end being free from the animal, 
When the animal is in motion this operculum lies transversely 
across the upper side of the posterior part of the animal’s foot. 
The nucleus of the young shell is white and glassy, and after a 
few turns the spire resembles a bluntly pointed, round peg. After 
this, the upper end of the whorls rapidly enlarges, as also does the 
length of the whorls from the anterior end of the shell to the 
shoulder. 
In the adult the body of the shell is covered with numerous 
revolving lines, more prominent near the anterior end of the shell. 
On the spire of some specimens there are also strong revolving 
lines, while on others these lines are entirely obsolete. The shoul- 
der of the last whorl is rather concave and forms a shallow sub- 
canal around the shell at the base of the spine, but this, like all 
other characters of shells, is very variable, and in some individ- 
uals it is absent. 
The whole shell is covered with a dirty yellowish epidermis 
that frequently darkens into chestnut color. The shells are quite 
brittle and very frequently broken, which perhaps is due to the 
thin, sharp outer lip, and an excessive amount of carbonate of 
lime in their composition. The bungling manner in which the 
animal repairs these fractures does not add to the beauty or at- 
tractiveness of the shell, which even in its perfect state is not very 
inspiring, especially when we consider the beauty of many other 
cones. 
3051 Terebra simplex Cpr. 
The animal that inhabits this shell is of a pure, pearly white 
color, without spot or blemish. When fully extended, its foot is 
about 1-3 the length of the shell. The proboscis is slender, about 
as long as the foot of the animal, gracefully curved over the back 
of the shell, and when the animal is in motion it forms an interest- 
ing and conspicuous part of the creature, and seems out of all 
proportions in its length to the rest of the animal’s body. This 
animal has no tentacles, but the eyes are situated on mammillated 
tubercles that protrude from the body midway between the foot 
and proboscis. The eyes are small, dark and keen; the foot is 
truncated in front and rounded behind. The operculum is carne- 
ous, unguiculated in form, and lies on the upper side of the pos- 
terior part of the foot. This shell is abundant at San Diego and 
southward.”’

3053 Eulimella occidentalis 
‘Shell small, turriculated, white, shining, transparent, consist- 
ing of about nine rather flattish convex whorls, with a single fine, 
revolving threadlike lirze above the periphery, and with very fine 
microscopic revolving strie beneath, observable only with a good 
glass and light; suture deep; aperture subquadrate; lip simple, 
acute; columella straight. Length 4, breadth 1 mm.”’ 
Type locality:—mudflats between tides, San Diego, Cal. 
‘The above title is rather unfortunate, as it does not describe 
a new Bulimulus, and Dr. Dall says the shell proves not to belong 
to the Pyramidellid family, but a species of Albina (see U. S. nat 
mus pr 39:410).
