TURRITELLA muricala. 
TAB. CCCCXC1 X.—Jigs. 1 and 2. 
Spec. Char. Subulate, transversely striated ; striae 
elevated into spines upon numerous small, 
arched costae. 
Less than an inch long ; the upper edge of each whorl 
is flattened ; the small spines with which the spire is 
roughened are most prominent upon the edges of the 
whorls : the convex base is free from spines, and the 
striae upon it are much elevated and sharp. 
We are indebted to Thomas Meade, Esq. for the 
means of exhibiting this elegant little shell. The group, 
which forms one of the many rare specimens contained 
in his rich cabinet, was found at Steeple Ashton: it con- 
tains also portions of Turbo muricatus (tab. 240, f. 4), 
and of an unfigured Murex. 
We have another specimen in the same kind of Clay 
as the following, and also from Robinhood’s Bay : this 
is accompanied by T. muricatus, indicating a contem- 
porary formation with that of Steeple Ashton.
