 Brod. Sp. Concli. 



" C. testa elongata, ventricoso-cylindracea, pallide fulva, anfrac- 

 tus basalis limbo apicem obliteratuin prsetereunte, producto, patulo, 

 carinato, subreflexo ; columella 4-plicata. 



" In aetate provecta, testa tegmine vitreo penitus adoptera. 

 Apex in junioribus exsertus subglandiformis. 



" Shell elongated, somewhat cylindrical, but ventricose towards 

 the middle, reddish yellow, which becomes paler in full grown spe- 

 cimens, covered with a dark brown epidermis, which is entirely 

 coated in adults with the enamel-like glaze. The spire and apex 

 are almost entirely obliterated in full grown individuals, and the 

 reflected upper border of the body-whorl exposes a wide, somewhat 

 excavated, snout-like area, from which the species obtains its name. 

 The pillar has four plaits, the last being comparatively small. The 

 shell grows to a large size. The author possesses a shell of this 

 species, to which numerous Coronulce (C/telonobue, Leach,) and 

 Crepidula are attached; the animal has buried the majority of 

 these adhesions under the thickest coat of enamel-like glaze 

 hitherto observed on the shell of the species ".

5. Cymba porcina (pi. lxxix. f. 1, 5, 9, 16, 18. pi. lxxx. 

 f. 20.) Lam. Anim. s. vert. 



" C. testa subcylindrica pallide fusca ; anfractus basalis limbo 

 apicem subobsolctum vix supereminente, patulo, tantum non piano, 

 subcarinato ; columella biplicata. 



" Shell subcylindrical, whitish, covered with a thin ash-coloured 

 epidermis, which is coated by a silvery enamel-like pellicle, extend- 

 ing over about | of the shell. The apex is more visible than in 

 Cymba proboscidalis, but the spire is entirely concealed. The 

 upper border of the body-whorl is less reflexed than it is in that 

 shell, and the area, though very open, is less excavated. In fine 

 specimens the aperture is of a rich brown colour. The plaits on 

 the pillar are only two, the shell is very uniform in size to that of 

 Cymba proboscidalis ".
