SERAPHS. Montfort. 
Sen. Cuar. A convoluted, elongated, univalved, 
shell; spire internal, concealed ; base truncated; 
mouth longitudinal, extending to the apex of 
the spire; lip sharp ; columella smooth. 
Mloxrrorr has taken the only species known bearing 
the above characters from the Genus Terebellum in 
which La Marck had placed it, and we think, justly 
ranked it as a type of anew Genus. It is distinguished 
from Terebellum, by the wholly internal spire, otherways 
the narrow form of the mouth which is almost linear 
ebove and broad below with a truncated base, and the 
general shape of the shell bring them very near together. 
There are at least two species found at Grignon, one 
of them is longitudinally ribbed.
