apicem subobliteratum supereminente ; columella tripHcata ; fauce 

 rubiginosa. 



" SlieU elongated, irregularly cylindrical, pale, (except on and 

 near the pillar and in the aperture, where it is of a rich rusty 

 brown) covered with a pale brown epidermis, which is entirely 

 coated in old individuals with a brown enamel-like glaze. The 

 apex of the shell is almost obHterated, and the border of the spire 

 and body-whorl, wliich is less sharp than in the species described, 

 is produced somewhat beyond it, exposing a rounded excavated 

 area, deeper, but much more contracted than that of the shell of 

 Cijmha poTcina. The pillar is three-plaited '\

7. Cymba olla (pi. Ixxix. f. 3, 4, 11.) Linn. Syst. Nat. 



" C. testa, ventricosa, paUide luteo-fulva ; spira brevi, canalicu- 

 lata, apice subconico, exserto ; columella 2-plicata. 



" Shell ovate, ventricose, pale fulvous, covered with a thin pale 

 brown epidermis, which is coated with an enamel-like glaze from 

 near the pillar to about two-thirds of the shell. The subcorneal 

 apex is exposed as well as the spire, wliich last, together with the 

 upper part of the body-whorl, is rounded and deeply channelled. 

 Pillar with two-plaits".

8. Cymba gracilis (pi. Ixxix. f. 15. pi. Ixxx. f. 24.) Brod. 

 Sp. Conch. 



" C. testa, subcyHndrica, albo rufoque nebulosa ; spira sub-exca- 

 vata, apice subglandiformi conspicuo ; labii, limbo spii'am versus 

 inilexo ; columella 4-phcata. 



"Shell subcyhudrical, clouded with white and reddish. The 

 spire somewhat excavated, and the subglandiform apex conspi- 

 cuous. The area much less, and the channelling much shallower 

 than in C. cymbimn ; the piUar, wliich has four plaits, much straigh- 

 ter,the aperture narrower, and the whole shell more slender and sym- 

 metrical. The sharp upper border of the Hp is very much inflected 

 towards the spire, and the shell is covered with a tliin brown epi- 

 dermis, which is coated with the enamel-like glaze for about one 

 third of the shell, beginning near the pillar. There is reason to con- 

 clude that in very old specimens this coating extends much further"'
