Hab. ? 



A small stout species, of which the accompanying figure 

 is a magnified representation. It is strongly varicose, and 

 the sinus of the lip is unusually distinct. The aperture is 

 verj' much contracted, with the columella of an intense 

 rose-colour.

The Peruvian Stkombus. Shell somewhat triangidar, 

 thick, ponderous, recurved in a twisted manner at the 

 base, spii'e rather depressed, acuminated towards the 

 apex, whorls spirally ribbed, obtusely angled at the 

 upper part, tubercled at the angle, middle dorsal 

 tubercle vei-y prominent, lij) largely triangularly di- 

 lated, slightly lobed above, columella wi'inkled at the 



upper part ; yellowish-chestnut, sometimes a little 



marbled, columella and interior of the aperture car- 



nelion-red.

 Hah. Bay of Caraccas, "West Columbia (on the reefs at 



low water) ; Cuming. 



This fine species is remarkable for the triangular dila- 

 tation of the lip, and for its general massive structiu-e, the 

 columella and interior of the aperture being of a deep car- 

 nelion-rouge colour. Several fine specimens wore collected 

 by Ml-. Cuming in the above-named locality. 



Species 7. (Fig. a, b, Mus. Cuming.) 

 Stkombus fusiformis. Stromb. testa fusiformi, spird 

 valde acmninntu, upicem versus varicosd, anfractibus 

 JHxta suturns marginatis, lavibus, ultimo basi et pone

 The fusifokm Strombus. Shell fusiform, spire much 

 acuminated, varicose towards the apex, whorls mar- 

 gined next the sutures, smooth, last whorl ridged at 

 the base, and, in a rayed manner, behind the lip, lip 

 rather thickened, reaching up to the suture of the 

 penultimate whorl, wrinkled witliin, columella finely 

 wrinkled ; white, banded and marbled in an inter- 

 rupted manner with red-brown, interior of the aper- 

 tm'e tinged with scarlet.

 Hab. North Australia ; Jukes. 



An extremely interesting species, partaking of the cha- 

 racters of Rostellaria, inasmuch as the lip reaches over the 

 body-whorl to the suture of the one preceding. The locali- 

 ties Red Sea and Indian Ocean, given, without authority, 

 by M. Deshayes, are probably erroneous, the specimen 

 here figured being collected by Mr. Jukes in II. M.S. Fly, 

 at North Australia.
