CERITHIUM funatum. 
TAB. CXXVIIL 
Spec. Char, Conical,, elongated, with two obtuse 
crenulated transverse ridges upon each whorl ; 
upper part of each whorl thickened and tuber- 
culated ; mouth squarish ; base smooth. 
The tubercles upon the upper part of the whorl form, 
in some specimens, a kind of corona : the last whorl 
only differs from the others, in exposing two more 
transverse ridges ; the mouth has a small canal at the 
upper edge ; the beak is rather short. Whorls ten or 
eleven. 
This elegant species seems to have been common at 
Hordle Cliff, when Mr. Iremonger procured it ; the indi- 
viduals are sometimes neat and white, with a mixture of 
sand and marie, or stained with ochre; sometimes they 
are less sharply preserved with a grey or greenish sandy 
mixture about them, and occasionally the ornament and 
striae are obliterated to so plain an appearance, that the 
species can scarcely be recognized without very careful 
comparison, the ridges, &c. varying more or less accord- 
ing as they are worn, but commonly having the most 
distinct appearance about half way from the apex I 
have named it from the resemblance of the costa to small 
cords.

A. Mantell, Esq. collected in 1802 or *803. Fig. 2

me by the Rev. Mr. Iremonger.
