848 MOLLUSCA. MURICID^. Fusus. 



cent shells were thrown upon the sands at Warren's Point, after a severe 

 thunder storm. 



EXTINCT SPECIES. 



1. p. nexilis. — Obovate, clavate, with decussating elevated striae ; spiral 



striae uniform, most prominent ; spire slightly produced (Murex nexilis, 



Brander, f. 55.) Soiver. JNIin. Conch, t. cccxxxi London Clay. 



2. P. Greenwoodii — Pyriform, with a short produced spire, reticulated with 



scattered elevated striae ; beak pointed ; shell thin Sower. IMin. Conch. 



t. ccccxcviii. — Crag. 



Two species are noticed as figured by Brander, whose work I have no op- 

 portunity of consulting, viz. f. 52, 53, and 54, which last is by Parkinson 

 (Org. Rem. 67-) considered as agreeing with Pyrula Icevigata of Lamark, whUe 

 Mr Mantell (Geol. Suss. 268.) denominates it P. bulbiformis,—{. 52, 53, the 

 Murex pyrus of Brander. These two species occur in the London Clay. 



Gen. LXXIX. FUSUS.— Shell pisiform, ventricose in the 

 middle, spire produced ; right margin of the canal patu- 

 lous. 



* Whorls destitute of longitudinal ribs. 



329. F. antiquus. — Whorls eight, ventricose, with obsolete 

 waved spiral striae, crossed by longitudinal wrinkled Hnes of 

 growth.

Don. Br. Sh. t. xxxi.— M. desp. MonL Test. Brit. 256 — In deep bays, 



common. 

 Length from 4 to 6 inches, greatest breadth between 2 and 3 ; white, the 

 inside with a yellowish tinge ; cuticle absent ; whorls thick, rounded, rather 

 coarse on the surface ; aperture ovate, the outer lip thin at the edge, inner 

 lip smooth, canal short, nearly straight. The animal is white, with a cor- 

 neous pyriform lid. It is used as a bait for cod, and sometimes as food. The 

 shell, suspended horizontally, is employed in the Zetland cottage as a lamp, 

 the cavity containing the oil, and the canal the wick. Dr Turton mentions 

 (Conch. Diet. 69.) two varieties in the shell ; the first with the whorls nearly 

 separated, and the second leaving the whorls furnished with longitudinal 

 ribs : in a specimen which I possess, the whorls are prominentl}'' angular in 

 the middle, and the specimen bears a close resemblance to the figure of Buc- 

 cinum carinatum of the Conchological Dictionary. 



330. F. corneus. — Shell lengthened, spirally striated ; the ca- 

 nal produced and slightly recurved. 



Buccinum angustius. List. An. Ang. 157. t. iii. f 4. Conch, t. Dccccxiii.

Length 3 inches, breadth about 1 ; shell white, usually covered with a 



thick brown epidermis ; whorls nine, compressed with a deep separating line ;
