170 PLEUROTOMA. 
C. B. Adams changed the name of this species to Reevet 
because he had previously described a shell under the name of 
violacea, but as the latter is a Bela, Hinds’ name may stand. 
P. vertebrata, EH. A. Smith (figs. 29, 29a), is probably synony- 
mous. 
P. pEcLIvIs, Martens. PI. 4, fig. 41. 
Shell multicarinate, the carine stronger and fewer than in the 
preceding species ; canalsomewhat more produced and narrowed; 
sinus shallow ; columella not plicate ; color light reddish fulvous. 
L. 33, diam. 11 mill. 
Japan. 
P. r1Losa, Marrat. 
Shell acuminately turreted; whorls convex, with numerous 
prominent revolving carinz, the interstices narrow, obliquely 
longitudinally striated; white, the apex tinged with fuscous; 
canal very short; sinus ample. (No dimensions.) 
W. Africa. 
A white shell, corded with transverse, thread-like bands. The 
Pl. violacea, Hinds, Pl. crispata, Crist. et Jan., and several others 
are similarly corded and closely allied shells. 
The above is an unfigured species, which I have not seen. 
P. RETUSISPIRATA, E. A. Smith. 
An unfigured species, L. 7°75, diam. 2°5 mill. Habitat unknown ; 
it is said to have for its nearest relative ‘““P. violacea, Hinds, 
from which it differs in form somewhat ; the apex is blunter, and 
there is but a single nodose liration around the middle of each 
whorl, whereas Hinds’ species possesses two.” Columella with 
two minute plications. 
P. coanaTa, EK. A. Smith. 
Unfigured. L. 24,diam. 7 mill. Australia. Differs from P. 
violacea, to which it is closely related in color (being luteous 
white, purple-tinged towards the apex, the carine white), in the 
number of carinz, twelve, and more produced spire. “ It is still 
more nearly allied to P. vallata, Gould, from which it differs only 
in size and the presence of only one plication on the columella, 
whereas P. vallata possesses two. It may be merely the adult 
of the latter species.”
