specimens of the same species in the Paris Museum, and that it was 

 the intention of M. F. Cuvier to have described them ; he should 

 therefore propose the name Cuvieri be used to distinguish the spe- 

 cies. 



The Secretary also called the attention of the Members present to 

 a species of Musk Deer, from Sierra Leone, which had been brought 

 from that part of Africa by Mr. Whitfield, who had kindly allowed 

 it to be exhibited to the Meeting. In general colour, and in the 

 markings on the throat, this species most nearly resembles the Mos- 

 chus Sanleyanus, but its body has spots and markings nearly similar 

 to those in the M. meminna ; it is much larger, however, than either 

 of these species, being, in size, about midway between them and the 

 M. moschiferus. The chief interest attached to this animal is the 

 locality in which it is found, the well-established species of Mos- 

 chus being either from the continent of India or the islands of the 

 Indian Archipelago. Mr. Ogilby stated that the present animal 

 could not be identified with the Moschus Guineensis of Brisson, 

 Gmelin, and some other of the older authors ; it was therefore ne- 

 cessary to give it a new name, and he proposed for that purpose the 

 name of M. Aquaticus, in allusion to the peculiar habits of the spe- 

 cies which will be described more at length in the Transactions of 

 the Society. 



June 9. — William H. Lloyd, Esq., in the Chair. 



A paper " On Parthenia, a new genus of Recent Marine Shells or 

 Mollusks, containing British Species," by the Rev. R. T. Lowe, 

 M.A., was then read. 



Genus Parthenia. 



Testa eximie turrita, acuminata, imperforata, plerumque lactea, 

 epidermide pallida s. fere nulla ; spira apertura longiore ; anfracti- 

 bus plurimis, costis striisque eleganter sculptis, ssepe cancellatis. 

 Apertura ecanaliculata, ovata, integra : columella simplex, antice 

 effusa, postice aliquando torta s. plicata : labrum tenue, simplex. 



Obs. Testae figura et sculptura elegantissimse, parvulae. Animal 

 corpore admodum spirali ; pallio simplici, ecanaliculato ; pede antice 

 abrupte truncato, postice attenuato exappendiculato, operculifero. 

 Tentacula duo, triangularia s. prismatica, basi coalita, oculis sessi- 

 libus, superne ad basin internam positis, approximatis. Buccie la- 

 biates coalitse, infra tentacula exsertse, proboscidem abbreviatam, 

 depressam, profunde emarginatam s. bilobam referentes. Opercu- 

 lum apertura? fere magnitudine, corneum, tenue, ovatum, integrum ; 

 nucleo ? 



Obs. Animal marinum, branchiis pectinatis, corpore capiteque 

 simplicibus, sc. nee velo nee membranis neque ciliis instructum. 

 Tentacula figura fere Limncea ; sed elongatiora, e membrana longi- 

 tudinaliter ab apice ad medium basis conduplicata constare videntur. 

 Figura pedis inter Gasteropodes non siphoniferos infrequentior, in 

 Rissois tamen seque obtinet. 



Genus et animale et testa distinctissimum, cum Melaniis, Evlimis 

 TurritelliSy &c, a testaceologis recentioribus diutius confusum.
