tHE SMAGLER: SEA-SHELLS 203 
Janthina exigua, Lam., the Violet Snail, (Ian- 
thina trifida). Out on the wide ocean lives the 
species with the above name. It is kept at the sur- 
face by a singular raft which it secretes, and it 
feeds upon small jelly-fishes. The shell is small 
and shaped much like that of a land snail. It is 
thin and delicate, and has a deep notch in the outer 
lip. The color is deep violet, quite unlike that of 
any other shell. Though it usually lives far out 
at sea, some shells get washed to the shore; but 
they are comparatively rare on our coast. 
Eulima micans, Cpr., the Shining Eu- 
lima, comes next on our list. The shell 
has a beautifully polished, slender shell, 
with a very sharp apex and an elongated 
aperture. Large specimens grow to the 
size indicated by the cross in Figure 
214. The color is nearly white, though the shell is 
somewhat dark near the apex. It could scarcely 
be mistaken for any other species. It is found 
from British Columbia to San Diego. 
Eulima rutila, Cpr., the Red Eulima, resembles 
the last species but is very small and slender. Its 
color is rosy and the base of the shell is lengthened. 
There are several other species the shells of 
which are small, being only a quarter of an inch 
or less in length. One of these is known by sev- 
eral synonyms: Hulima distorta, E. incurva, and 
E. falcata. Its shell is curved, as all the names in- 
dicate. It has a variety with the singular name 
E. yod.
