Hab. in Oceano Africano, juxta littora. 



Desc. Shell obovate, tumid, ventricose, of a brownish red, covered with a strong brown epidermis, over which an enamel-like 

 glaze is extended from the pillar over about a fourth part of the shell, leaving the epidermis of the back uncoated. In full grown 

 specimens the spire and apsx are entirely concealed, and the upper border of the body whorl, which is carinated and somewhat 

 reflected, overhangs both, so as to form an open, somewhat round concavity. The pillar is four plaited. 



In younger individuals and especially in those lately produced, the shell is thin, of a brownish red mottled with white, and 

 the rude apex of the spire appears entirely uncovered. •

Icon. fig. 3. b. 



Hab. in Oceano Africano. 



Desc. Shell ovate, tumid, elongated, pale-brown or whitish, covered with a brownish epidermis, over which an enamel-like 

 glaze extends from the pillar about as far as it does in Cvmba Neptuni. The rounded apex of the spire in full grown individuals is 

 very nearly concealed, and is over-hung by the border of the spire and body-whorl, so as to present the appearance of a shallow 

 winding excavation, (at the bottom of which the tip of the apex may be discerned,) differing entirely in character from that which 

 is observed in Cymba Neptuni ; the aperture is much less patulous ; and the whole shell is more symmetrical and melon-like. 



CYMBA PATULA. Fig. 4 et 4 b. 



C. testd tumidd labium versus gibbd, brunneo-rubente, anfractiis basalis limbo excavato, subreftexo, apicem subrotundum exser- 

 tum vix pratereunte ; columella 4-plicatd ; aperturd valde patuld. 



Icon. fig. 4, et 4 b. 



Hab. in Oceano Africano, juxta littora. 



Desc. Shell tumid, gibbous towards the outer lip, brownish red, covered with a brownish epidermis, partially coated, t.s 

 in the last species, with an enamel-like glaze. The spire is excavated and open, the rounded apex partly apparent, and the upper 

 border of the body- whorl carinated, and somewhat reflected. The pillar, which has four plaits, is straighter than that of Cymba 

 Neptuni and Cymba Tritcnis, and the aperture from the gibbous extension of the outer lip is very wide. The shells of all the 

 individuals of this species seen by the author have the appearance of being full-grown, and are very much inferior in size to the 

 two species last described. 



CYMBA PROBOSCIDALIS. Fig. 5, a. b, c, d. 



C. testd elongatd, ventricoso-cylindraced, pallide fulvd , anfractiis basalis limbo apicem obliteratum pratereunte, produ:to, patttic-

 Obs. In estate provectis, testa tegmine vitreo penitus adoperta. 

 Apex in junioribus exsertus, subglandiformis.
