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 fulgidm 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 liae ; 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. scripte.— Whorls three, smooth, marked with brown, letter-like 
lines: aperture suborbicular. — A^ms, 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 separated by an elevated line. — Adams, Linn. Trans, iii. 253.-—Coast of 
Pembrokeshire. 
200. T. resupinatus — SemipeUucid, glos.sy, horn-coloured ; aperture large, 
the whorls at the tip turned backwards. — Helix, FTafllr. '^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. 1. i. f. 25 — Sandwich, not 
common. 
202. T. reticulatus. — White, subpeUucid ; one whorl ; reticulated ; a slight 
pillar-cavity; aperture round. — Helix, Walk. Test. Min. 1. 1. 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. coarctatus. — 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./ascia^Ms.— 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. Corneous, pellucid, glossy ; whorls two, finely stri- 
ated across ; with a pillar.cavity.— Helix nit. Adams, Linn. Trans, v. 4. t. i.
