pretty uniform : the beak has a slight bend : within the 
lip are a few small plaits, and the striae of the surface are 
distinguishable upon the columella. The length of the 
inoutli and beak together is half that of the whole shell. 
This was sent me from Barton Cliff, by Miss Salis-

MUREX carinella. 
TAB. CLXXXVIL— Fig. a and 4. 
Spec. Char. Rather elongated, with many longi- 
tudinal undulations, crossed by strong elevated 
unequal striae ; whorls convex, subcarinated 
in the middle, the last contracted towards the 
beak ; beak open, rather slender ; aperture 
obovate. 
V ery similar to the last ; its difference consists of the 
subcarinated form of the volutions, which is chiefly pro- 
duced by the slight enlargement of one of the striee. 
This was favoured me along with the last : it bears 
some resemblance to the M. craticulatus of Brocchi’s, 
tab. 7, f. 14 ; but the last whorl is not so ventricose, 
neither is the carina so strong.
