gpEC. Char. Subturrited ; body covered by broads 
transverse sulci ; the remaining whorls smooth 
with two sulci along their upper edges. 
Syn. Murex interrupts, Pilkington , in Trans. 
Linn . Soc. VII. p. 117 t. 11 , f. 5. 
Shell about twice as long as wide ; a broad flat space 
runs along the smaller whorls, above it are two sharp 
furrows ; the last whorl in full grown individuals is 
quite covered with furrows, which are broader than in 
the other whorls, it is also convex, the right lip is 
plaited within, the left so thin that it receives the impress 
sion of the sulci beneath it and so becomes striated ; the 
beak is elongated and slightly curved. 
One of the varieties of this shell was first published by 
Mr. Pilkington, who discovered it in a collection of 
Hampshire fossil shells made by I. T. Swainson, Esq. ; 
others have since been noticed at Barton by Lady Bur- 
goyne, from whose choice cabinet the specimens fig. 1 are 
taken; I have since received it from Miss Beminster, and 
an unknown Friend ; in the specimens from these latter 
persons the band does not extend so far down the spire 
as in those collected by Lady Burgoyne, (see fig. 2.)
