 also found it at the Cove, Cockbum'spath. 



Shell ovato-conical, white, covered with a pale-yellow hairy epidermis, 

 strongly striated spirally. Two or three strioe, much larger than the 

 rest, encircle the top of each whorl. Whorls 7, much rounded, ta- 

 pering to a fine point. Aperture blueish-whitc, very glossy, somewhat

ScALARiA Trevclyanay i. p. 263. 



Hah. Coldingham Bay, in deep water, rare. 



Shell pale-rose coloured, elongated, with 12 rounded finely tapering whorls, 

 crossed by 17 ribs varying in thickness ; ribs interrupted by a separating 

 line ; intermediate spaces very glossy, distinctly striated transversely 

 and indistinctly in a spiral direction. Aperture white, nearly round. 

 Length l;|^th ; diameter of the base ^^ths. 



I have again described this shell, for Dr Johnston's description has been 

 founded on young and worn specimens. When young it is of a uniform 

 cream-colour, with the ribs so thin as to look like some other species. 

 The only British Scalaria with which the shell is likely to be con- 

 founded is Sc. Turtoni, from which, however, it may be distinguished 

 by the number of its ribs, by having as many whorls when it is an inch 

 shorter, and by the peculiar marking of the spaces between the ribs. 



KissoA semicostata, shell white, glossy ; ribs abbreviated on the 

 body-whorl, on the under part of which there are strong spiral 

 striae. Length 1 line. Cingula semicostata, Flem. Brit. Anim. 307.

 310.

Capulus militaris, shell reticulated by longitudinal and transverse 

 stria3, Diam. fths. Flem. Brit. Anim. 364. 



Hab. Coldingham Bay, adhering to shells and other marine bodies in deep 

 water. 



Capulus antiquatus, shell covered with concentric ascle-like wrink- 

 les, formed by the layers of growth. Length Aths ; breadth f'cths.
