[FicuLOPSis, Stoliczka, referred by him to the Volutidae, is a Ficua with 

 the addition of columellar folds. I agree with Mr. Gabb in including 

 it in the Fieulidae = Pyrulidse.] 



PLEIOPTYGMA, Conrad. Subfusiform; aperture long; columella with 

 very oblique plaits, numerous, alternated in size, or irregular; the 

 largest being the second one from above. 



P. CAROLINENSIS, Conrad. PI. 4, rig. 48. Miocene, So. Carolina. 



CRYPTOCHORDA, Morch. Shell smooth, Volutiform, enameled; 



columella without plications. Tertiary. Seems to connect Voluta 



with Harpa. 

 C. 8TROMDOIDE8, Gmel. PL 4 fig. 47. Tertiary, France. 



[OTOCHEILUS, Conrad. An uncharacterized genus placed by its author 

 in Volutidae. The type is lost, but the second species, 0. Mississippi- 

 ensis, Conrad, has been referred by Prof. Heilprin to Cythara in 

 PleurotomidaB - to which determination I agree* ] 



GOSAVIA, Stoliczka. Shell convolute, spire turbinated, last whorl 

 inversely conical; aperture narrowly elongate, base emarginate; lip 

 sinuate at the suture; columella plicated, anterior plicae strongest. 

 Cretaceous, Europe and India. 



Stoliczka refers this genus to Conidse, as he does also doubtfully 

 Imbricaria and Cylindra, which he considers closely related. The two 

 latter are known to be in no way closely related to Conus, and Go&avia 

 possesses every characteristic of a Volute; indeed I cannot separate it 

 readily from such forms as V. musica. 



G. INDICA, Stol. PL 4, fig. 49. India. 



Genus CYMBIUM, Klein. 



The animal is large compared to the size of the shell, when 

 expanded. The foot partially covers the shell, which is sunk 

 into its substance. There is no operculum, Ovoviviparotis; the 

 young when born being of a large size and covered with a shell 

 with a large irregular callous apex. They leave the parent when 

 they have attained a length of about an inch; the brood appear- 

 ing to consist of four or five individuals. Adanson observes 

 that the high winds of April cast the " yet " up in such vast 

 (jiiantities as sometimes to cover the shore; the natives of 

 Senegal using them as food. The species are limited in distri- 

 bution ; one being an inhabitant of the Mediterranean Sea, the 

 others of the West Coast of Africa. 



Cynibium is separated from Melo by its flat or slightly
