OTINA. Ill 



Shell shaped like a, miniature Haliotis or Velutina, rather 

 thin, semitransparent, of a somewhat dull and dusky hue: 

 sculpture, microscopic, slight, wavy, and close-set longitudinal 

 striae, covering the surface with the exception of the apex, 

 which is quite smooth and glossy: colour reddish-brown of 

 different shades, with a purplish tinge: epidermis indistinct: 

 spire minute, conspicuous although not prominent; apex 

 obliquely twisted inwards : ivhorls 2 only, convex ; the last 

 occupies nearly all the shell, and is expanded in front ; apical 

 whorl bulbous : mouth forming a short oval, and exceeding in 

 size two-thirds of the under surface ; it does not expose the 

 interior of the spire ; inside polished : outer lip sharp-edged : 

 inner lip consisting of a narrow rim behind the pillar, and 

 continuous with the outer lip: pillar broad, flattened, and 

 excavated. L. 0-1. B. 0*075. 



Yar. Candida. Pure white. 



Habitat : Rocks between tide-marks, on. Lichina 

 pygmaa and other small seaweeds, as well as inside the 

 empty walls of Balanus crenatus, and among dwarf 

 Mytilus edulis, on the northern and southern coasts of 

 England, South Wales, Channel Isles, and west of 

 Ireland; Sandwich and Reculver (Walker); Isle of 

 Man (Forbes); Arran, N.B. (Norman). It is not 

 uncommon; and if properly searched for, it would 

 doubtless be found in every suitable locality. The 

 variety occurs in a cave at Sark. The known foreign 

 range of this species is at present limited, viz. Etretat, 

 Normandy (J. G. J.); Brest (Daniel, fide Baudon); 

 Quiberon and Piriac, Loire- Infer ieure (Tasle and Cail- 

 liaud) . 



It is a restless little creature, and when put into sea- 

 water crawls directly out of it. 



Walker's figure 17 is not a bad representation of this 

 remarkable shell. Brown described it as Galericulum 

 ovatum and G. otis.
