FAMILY CANALIFERA. © 
: Genus Pirvroroma.—Lamarck. 
’ P. cancellata. Pl. 1, fig. 13. 
= 
P. testa sub-fusiformi, sub-crassa, cancellata, imperforata, striis 
longitudinalibus obliquis; spira acuta ;sinu magno, prope suturum; 
anfractibus septenis, convexis; suturis impressis ; columella levi, 
polita ; labro serrato, intus striato ; apertura longa ; canale brevi. 
Shell sub-fusiform, somewhat thick, cancellate, longitudinal 
strie obliqie, imperforate ; spire acute ; sinus large, near to the 
suture; whorls seven, convex; sutures impressed; columella 
smooth, polished ; outer lip serrate, within striate ; mouth long; 
canal short. : 
Length 3. Breadth -15 of an inch. 
Remarks.—This pretty little shell is one of the most fusiform 
Pleurotome that Ihave seen. The mouth is half as long as the 
shell. The transverse striee are much more elevated than the 
longitudinal ones, which on the last whorl become almost obso- 
lete.. The-channel is shorter than in most Pleurotome, but is 
still very evident. The first and second whorls are smooth, the 
third has only longitudinal stria, and the rest are cancellate. 
Genus Turpiwetta.— Lamarck. . 
T. fusoides. Pl. 1, fig: 14. 
TT’. testa fusiformi, crass4, imperforata, transversé ac longitudi- 
naliter striata, longitudinaliter costata, costis maximis ; spira acuta; 
anfractibus septenis, convexis ; suturis parvis, irregularibus ; colt- 
mella polita, quadriplicata; labro intus striato ; apertura sub-ellip- 
tica, canaliculata. 
Shell fusiform, thick, imperforate, transversely and longitudi- 
nally striate, longitudinally costate, with very large cost@; 
whorls seven, convex ; spire acute; sutures small, irregular ; col- 
umella polished, with four folds; outer lip striate within ; mouth 
sub-elliptic, channelled. 
Length -55. Breadth -35 of an inch. 
emarks,—In this shell there are eight striee on the inside of 
the outer lip, but as I have but one specimen, I cannot determine 
whether this is a constant character. They appear to be made in 
rows opposite every rib. The mouth is a little over half as long 
as the shell, being ‘30 in length. The general form of this shell 
is more that of a Fusus, than of a Turbinella.
