300 MOLLUSCA. PECTINIBRANCHIA. Turbo. 



suborbicular, the outer-lip thin and prominent, retrally, where it joins the 

 body- whorl nearly at right angles ; pillar-lip reflected, forming the cavity 

 behind ; operculum finely striated spirally. We have little doubt in con- 

 sidering the Helix fulgidus of Adams (Linn. Trans, iii. 254.), and the Turbo 

 fulgidus of Montagu, as the fry of this very common species. 



195. T. nivosus. — Whorls five, smooth, rounded, slender, 

 tapering to an obtuse point. 



Mont. Test. Brit. 326.— Coast of Devon, rare. 



Length about a line ; breadth two-thirds less. Whorls with the separat- 

 ing line deep ; aperture suboval ; inner-lip and pillar quite smooth and even ; 

 without cavity. 



The history of the remaining recent species is involved in obscurity, but 

 their characters are subjoined, according to the best information in my pos- 

 session. 



196. T. strigatus. — Shell white, whorls three, with three spiral ridges on 

 the larger volution.— Walk. Test. Min. 11. t. ii. f. 38.— Sea-salter. 



197. T. scriptus. — Whorls three, smooth, marked with brown, letter-like 



lines: aperture suborbicular Adams, Linn. Trans, iii. 65. t. xiii. f. 11-12. 



— Coast of Pembrokeshire. 



198. T. subrufus. — Smooth, opake, dull red, the upper part of each spire 

 marked with a white spiral band ; whorls five, somewhat angular above. — 

 Adams, Linn. Trans, v. iii. t. i. f. 18-19 — Pembrokeshire. 



199. T. canaliculatus — Pellucid, whitish ; the whorls five, fluted across, 

 and sepai'ated by an elevated line. — Adams, Linn. Trans, iii. 253 — Coast of 

 Pembrokeshire. 



200. T. resupinatus Semipellucid, glossy, horn-coloured ; aperture large, 



the whorls at the tip turned backwards — Helix, Walk. ^Test. Min. 1. t. i. 

 f 24. — Sandwich, very rare. 



201. T. globosus White, opake, glossy, smooth, globose ; whorls two ; 



aperture roundish. — Helix. Walk. Test. Min. 1. t. i. f. 25 — Sandwich, not 

 common. 



202. T. reticulatus White, subpellucid ; one whorl ; reticulated ; a slight 



pillar-cavity ; aperture round — Helix, Walk. Test. Min. 1. t. i. f. 26 — Re- 

 culvir, rare. 



203. T. striatus. — Greenish-white, pellucid ; whorls striated, reflected on 

 the back ; aperture oval — Helix, Walk. Test. Min. 8. t. i. f. 29 — Sandwich, 

 rare. 



204. T. coarclatus — White, pellucid ; whorls two ; aperture roundish, con- 

 tracted near the pillar-cavity — Helix, Walk. Test. Min. 8. t. i. f. 30 — Sand- 

 wich, not common. This is considered by Montagu (Test. Brit. 445.), as the 

 fry of a Helix. 



205. T. fasciatus.-— White, pellucid, smooth ; whorls three, the first tumid, 

 and marked with three spiral belts, of a rich marone colour, the middle one 

 broad, the lateral ones narrow ; aperture large, a slight pillar-cavity — Helix 

 fas. Adams, Linn. Trans, v. 3. t. i. f. 20-21.— Tenbigh. 



206. T. nilidissimus.— Corneous, pellucid, glossy ; whorls two, finely stri- 

 ated across ; with a pillar-cavity Helix nit. Adams, Linn. Trans, v. 4. t. i. 



f. 22, 23, 24.
