PLEUROTOMA priscus. 
TAB. CCCLXXXYX. 
Spec. Char. Fusiform, turreted, smooth; base 
transversely sulcated ; margins of the whorls 
striated ; lip wing-shaped. 
Syn. Murex priscus, JBrander , 25 et 44. Pleu- 
rotoma clavicularis, Lam . env . cle Paris , 69 ; 
Hist . iVaL sa/ts vert . 7, 98. 
The whorls are slightly convex and smooth, excepting 
two or three hollow lines, which are most conspicuous 
in young shells near their upper edges ; the base is 
drawn out almost into a beak ; it is blunt and strongly 
striated, the lip below the sinus is nearly semicircular. 
Brander’s figure of this shell is far from good, and that 
in the Encyclopedic M&thodique is worse. The former 
appears to have been overlooked by Lamarck, or he would 
not perhaps have changed the name. 
Common atHordweil, and near Paris. 
PLEUROTOMA fusiformis. 
TAB. CCCLXXXVII. —Fig. 1. 
Spec. Char. Fusiform elongated, rough, with 
deep transverse striee, and obscure longi- 
tudinal costse ; whorls subcarinated, with a 
striated band upon their upper parts ; aper- 
ture lanceolate. 
The deep striae leave between them ridges that are 
roughened, but not regularly crenulated by the lines of 
growth ; the band near the top of each whorl is nearly 
smooth, but it has arched striae upon it, following the 
sinus in the upper part of the lip. 
Found at Highgate, but rarely ; I have never seen it 
perfect.
