70 LEPAS. 



Variety, much stronger and thicker, of a deeper red co- 

 lor, 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, ear-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, horn-color or 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 

 of 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' 

 pressed 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. Walker's figure is a very good 

 representation, who justly remarks, that it differs from the 

 H. Icevigata, in not being striate. v. v.
