TURBO muricatus. 
TAB, CCXL.— Fig. 4 . 
Syn. Turbo. Smith's Strat . Syst. p. 49. Strata 
Identified , p . 20. Coral Rag. Plate f. 1. 
Spec. Char. Short, conical, with many muricatcd 
ridges ; lip plaited ; columella indented at the 
base. 
P oiNTED? 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.
