pretty uniform: the beak has a slight bend: within the 
lip are a few small plaits, and the striz of the surface are 
distinguishable upon the columella. ‘The length of the

MUREX carinella. 
TAB. CLXXXVII.---Fig. 3 and 4. 
Spec. Cuar. Rather elongated, with many longi- 
tudinal undulations, crossed by strong elevated 
unequal strie ; whorls convex, subcarinated 
in the middle, the last contracted towards the 
beak ; beak open, rather slender ; aperture 
obovate.

Venry 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 striz. 
This was favoured me along with the last: it bea 
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.
