TURBO muricatus. 
TAB. CCXL.—Fig. 4. 
Syn. Turbo. Smith’s Strat. Syst. p. 49. Strata 
Identified, p. 20. Coral Rag. Plate f. 1. 
Spec. Cuar. Short, conical, with many muricated 
ridges ; lip plaited ; columella indented at the 
base. 
a 
Porren, nearly as wide as long; the ridges are equal 
to the concave spaces between them, they are covered 
with short semicylindrical hollow spines, the formation 
of which around the edge forms the plaited lip: this and 
the indentation of the columella are two very essential 
characters. 
Common in the Coral Rag at Steeple Ashton and some 
other places; another shorter, but somewhat similar 
species, is found in Long Leat Park, and a third in the 
Pisolite: the three have been confounded together, but 
I hope hereafter to shew that they are quite distinct.
