LEPAS. 
Variety, much stronger and thicker, of a deeper red co- 
lpr, with the second volution much protruded and well 
rounded, without the longitudinal striae, and a full inch in 
diameter. 
Sandy coves of the southern and western coasts, and 
various parts of Ireland, v. v. 
65. Helix Otis. Ear shaped Snail-shell . 
Walker , fig. 17* 
Shell oblong, very convex, car-shaped, semitransparent, 
pale horn-color or covered with a dark purplish-brown 
skin, smooth or very faintly wrinkled transversely, some¬ 
what glossy : spires three, the first roundish-oblong, very 
large and covering nearly the whole shell, the others spi¬ 
rally turning on one side, like the crown of the Turbo pal* 
lidulus, well defined by the line of separation, but rather 
flat and obtuse; inside glossy, liorn-coloror purplish: aper¬ 
ture very large, extending over nearly the whole shell, 
roundish-oblong; outer-lip thin; pillar-lip a little thickened 
and flattish, but without any groove or cavity: length 
hardly a line ; breadth somewhat less. 
This minute and elegant species, for the first knowledge 
cjf which we are indebted to the Rev. Dr. Goodall, is found 
among the interstices of rocks which are covered at high 
water, on the Devonshire coast. It has something the 
contour of the Turbo pallidulus; but the primary volu¬ 
tion is more convex, and the lateral ones not so closely 
presaed to the body ; the aperture is of a more regularly 
oblong shape ; the pillar-lip is not placed so transversely, 
and it has no groove nor perforation. 
We have been informed that it was known to the late 
Mr. Montagu, who had intended to denominate it H. Auri¬ 
cula ; but as this name approaches too near to auricularia, 
we have called it Otis. Walkers figure is a very good 
representation, who justly remarks, that it differs from the 
H. laevigata, in not being striate, v. v. 
LEPAS.
