Buccinum neriteum.

buccinum spiratrum. — Linnceus. 



Mawe's Linn. pi. 24,/. 4. 



This genus has been separated from the G. Buccinum 

 by Lamarck, in consequence of the peculiar char- 

 acters of the umbilicus and of the columella, which is 

 prolonged at the lower end, and forms a canal occupy- 

 ing the remaining part of the left side. In every other 

 respect it possesses the same characters as the Bucci- 

 num. The E. Zeylanica is remarkable for the spines 

 with which the umbilicus is filled, and only existing 

 in that species. 



In the late Earl Tankerville's cabinet is an example 

 of the E. glabrata, in which the channel on the left 

 side is quite closed and concealed, rendering that dis- 

 tinction doubtful, as the sole guide by which Lamarck 

 has constituted this genus, and dismembered it from 

 the G. Buccinum.
