332 MURICID.S. 



scarcely glossy : sculpture, slight and flattened, but conspicuous 

 and regular spiral ridges, which are numerous on the body- 

 whorl, and consist of about 15 on each of the preceding whorls; 

 they become less distinct on the upper part of the body-whorl; 

 top whorl smooth ; there is an obscure basal ridge or keel : 

 colour whitish, tinged inside with purple: epidermis thin, bright 

 yellow passing into olive-green : spire elongated and tapering; 

 apex remarkably conical: whorls 7-8, convex and somewhat 

 angulated in the middle, compressed and shelving upwards to 

 the suture ; the last slopes towards the base, and occupies 

 about two- thirds of the shell: suture distinct but not deep: 

 mouth angularly oval, expanding outwards ; length (including 

 the canal) about one-half of the shell : canal extremely short, 

 wide, and open, almost straight, and ending in a large, deep, 

 and obliquely curved notch : outer lip> semicircular and pro- 

 minent, not contracted above ; edge somewhat reflected ; inside 

 or throat smooth and polished, often purplish -brown : inner 

 lip consisting of a porcellanous glaze, which varies in thickness 

 according to the age of the individual ; it is broad, but does 

 not extend far beyond the pillar as in the last species : pillar 

 flexuous : operculum large, horncolour, forming a long and 

 oblique triangle with a pointed apex and rounded base ; layers 

 of increase close-set ; a few impressed lines radiate upwards 

 from the nucleus. L. 4- 75. B. 2*5. 



Habitat : With F. Norvegicus, on soft ground, in the 

 coralline zone of Yorkshire, Durham, and Northumber- 

 land. I dredged a capsule in 78 f. on the east coast of 

 Shetland ; the same haul yielding the other species and 

 its capsule. Vadso, 100 f. ; two large specimens (Sars). 



This fine shell was discovered by a naturalist who has 

 just passed away, full of years, after a long and zealous 

 career. Old Bean of Scarborough (as he was familiarly 

 called) did much by example and kind assistance to 

 promote the cultivation of natural history in the north 

 of England ; and he was just and true in all his dealings 

 — not a common virtue in these times. The capsules 

 of F. Turtoni are pale orange, either solitary, or two 

 together and attached side by side, not to each other, 

 but to a rather broad membranous substratum ; they are
