OTINA. Ill 



Shell shaped like a miniature Haliotis or Velutlna, 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: luhorls 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 Up 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 

 Mytiliis 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. Gr. J.); Brest (Daniel, fide Baudon); 

 Quiberon and Piriac_, Loire-Inferieure (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.
