408 CYPR.^ID^. 



Shell forming a short spindle, thin, semitransparent, and 

 glossy : sculpture, minute, delicate, and rather close-set spiral 

 striie, which are more conspicuous at the extremities and in 

 young shells ; they are somewhat wavy, and slightly reticu- 

 lated by microscopic lines of growth : colour pale yellowish- 

 white, sometimes orange, and occasionally tinged with pink : 

 spire excentric, visible only in young shells, extremely short, 

 lying within the level of the upper canal ; it exhibits under 

 a strong magnifying-power a finely punctured appearance, 

 like the apex of lUssoa Jeffreysl : luhorls, apparently a single 

 tumid one which envelopes all the rest ; in the young may be 

 counted 3 convex whorls, the first of which is blunt and 

 mammiform : suture in the early state of growth slight, 

 afterwards covered over : mouth large and wide, somewhat 

 expanding, of an irregular shape in consequence of the 

 periphery projecting into it ; it is narrower above than below : 

 upper canal semitubular, expanding outwards, and having 

 the inner side or wall more or less twisted, thickened, and 

 white : lower canal very short and broad, usually straight ; 

 notch obliquely but not deeply incurved : outer lip flexuous ; 

 edge plain and prominent, now and then thickened within : 

 pillar excavated or indented, and girded by a twisted ridge. 

 L. 1. B. 0-5. 



Habitat : Coralline zone, on the coasts of Dorset, 

 Devon, and Cornwall ; Guernsey (J. G. J.) ; co. Gal- 

 way (Barlee); Macgilligan, co. Londonderry (Mrs. R. A. 

 Hyndman, fide Thompson) ; Turbot bank, co. Antrim 

 (Waller) ; Sound of Mull (Bedford) . Mr. Horace Mar- 

 ryat found it living among tufts of Tubularia indivisa, 

 in the Gouliot caves at Sark, at low water. Laskey 

 gives ^' Porto-bello sands ; '^ but such a locality seems 

 improbable. IM. Martin lias taken this species in the 

 Gulf of Lyons, regarding it as the young of 0. carnea 

 (Bulla carnea^ Gmelin), of which the 0. Adriatica of 

 Sowerby is perhaps a variety. 



If the present species should prove to be also a variety 

 of 0. carnea (wliicli differs only in its outer lip being 

 inflected and the edge notched), Pennant^s udimQ patula
