Notwithstanding the judicious separations from the 

 Geijus Valuta of Linne, made first hy Bruguiere, and after- 

 wards more largely by Lamarck, a careful examination 

 will, we think, convince the zoologist that a still further 

 division is necessary. 



It would exceed the limits prescribed by the nature 

 of this work to enlarge on a subject which may, perhaps, 

 be entered upon more minutely elsewhere. Our present 

 intention is merely to introduce to the reader a further 

 division of the Genus as left by Lamarck into the genera 

 Cymba^ Melo and Valuta, The student, when he comes 

 to consider this last Genus after the proposed separations, 

 increased as it has been by the new species which have

 and its islands, are meant to be included. At present there is no positive 

 evidence of any species of Cymha being found in the New World. But Captain 

 Marryatsawat the Cape of Good Hope, two shells, which, from his description, 

 were most probably C^^mJi^, and which the proprietor assured him came from 

 the Rio de la Plata. The geographical distribution of the Genus given above 

 oug:ht not, therefore, to be deemed conclusive.
