Desc. Shell pear-shaped, whitish, with a pale flesh-coloured tinge; back ventricose, transversely striated; lower canal 

 straightish, slightly reflected ; columella with an excavated depression within, near the base, and a strong pliciform tooth at the

 Ovula carnea, Lam. Anim. sans vert. VII. 368. Bulla carnea nonnull. 

 Hab. in Mari Siculo. Mus. Goodall, nostr., &c. 



Desc. Shell ovate, back gibbous, transversely slightly striated ; extremities, particularly the lower, slightly acuminated : 

 outer lip arched, toothed on the inside ; upper end of the columella forming a small thickish fold. 



A pretty little species of a reddish flesh-colour, from the Coral Fishery on the coast of Barbary, and also from the coast of 

 Sicily. 



OVULUM MARGINATUM. Fig. 15 and 16. 

 O. testa oblongo-ovali, ventricosd, ntrinque obtusiusculd, albd ; labii externi margine rotitndato, intiis denticulato, prop'e basin 

 depresso, plicato-deuticulato : columella superne dente pliciformi valido, prope basin depressd, infra uniplicatd : 

 marginibus externis labiorum aurantiaco-marginatis ; long. \ J, lat. T \, poll. 



Hab. . Mus. nostr. 



Desc. Shell of a rather oblong oval form, and obtuse at both extremities, white, particularly the front : the back with a 

 number of slightly-raised transverse lines ; border of the outer lip rounded, denticulated on the inner edge, depressed and plicato- 

 denticulated near the lower end ; upper part of the columella with a strong pliciform tooth ; near the base it is depressed, and 

 below it has a prominent fold or tooth : outer borders of the lips with an orange margin. 



An interesting species, much resembling 0. pyriforme in general appearance ; by altention to its peculiarities noticed in the 

 description, it will be easy to recognize it. A single specimen was found in Mr. G. Humphrey's collection, without locality-. 



OVULUM LACTEUM. Fig. 13 and 14.

 Hab. ad littora Insularum Oceani Pacifici. Mus. Goodall, Mawe, nost. 



Desc. Shell ovate, slightly gibbose, smooth, white, back with a few slight transverse angular lines ; edges thickened ; inner 

 edge of the outer lip denticulated, the teeth somewhat extended outwards in the form of short plicje ; inner edge of the columella 

 rather compressed, particularly near the base ; canals very short, that at the base produced by a pliciform tooth at the base of the 

 columella. 



Rather a rare species, which has occasionally been brought from the Islands of the South Seas, as well as from Haynani and 

 Timor. It seldom reaches the size of our specimen, but its proportions are not subject to variation.
