British Museum. By Epaar A. SMITH. 
[Continued from p. 218. ] 
Pleurotoma (Defrancia*) rubro-apicata. 
Testa ovata, alba, ad apicem rubra; anfract. 8, primi 2 minute 
granulosi, sequentes duo oblique exiliter reticulati, czeteri convexi, 
superne ad suturam canaliculati, costis tenuibus 12 (in anfr. 
ultimo haud ad basim attingentibus) et liris spiralibus 5-6 (in 
anfr. ultimo 16-19) supra costas subnodosis clathrati; apertura 
parva, longit. totius ad 42; szquans; labrum incrassatum, intus 
denticulis 8-9 munitum, juxta suturam subprofunde sed anguste 
fissum ; columella tortuosa, basi obliqua ; canalis angustus, brevis. 
Long. 53 mill., diam. 23. 
Hab. Japan ? 
The four apical whorls are red, the rest of the shell is white. 
The upper part of each whorl is distinctly channelled. 
Pleurotoma (Defrancia) capensis. 
Testa abbreviato-fusiformis, pallide fusca, infra medium anfracti 
ultimi fusca, interdumque hic illic fusco ac prope suturas albo 
maculata; anfract. 9, primi 2-3 convexi, minute reticulati, 
ceeteri superne angulati et tabulati, costis longitudinalibus graci- 
libus (in anfr. ultimo ad 12) et spiralibus fere que validis (in 
anfr. superioribus 3, in ultimo circiter 6 precipuis, atque alliis 
cirea caudam subgranosis) fortiter cancellati, intersectionibus 
acute nodulosis; apertura ad? longitudinis totius zequans, basi con- 
tracta; labrum incrassatum, intus denticulatum et ad suturam 
incisum, inferne cum columella rectiuscula canalem brevem leviter 
recurvum formans. 
Long. 133 mill., diam. 5. 
Hab. Port HKlizabeth, South Africa. 
This species is very closely related to the European D. 
reticulata, Bronn. It differs chiefly in the whorls being less 
rounded, more constricted at their base, and slopingly tabu- 
lated above; and the cancellation is rather coarser. ‘The colo- 
ration is similar. 
Pleurotoma (Defrancia?) asperulata. 
Testa fusiformis, lutescens ; anfract. 93, primi 23 leves, vitrei, politi, 
ceeteri perconvexi, sutura canaliculata sejuncti, costis tenuibus 18 
et liris spiralibus 8 supra costasleviter echinatis, concinne clathrati; 
* This section is employed, in the sense as restricted by Dr. Gwyn 
Jeffreys, for such species as have a cancellated sculpture, minutely reti- 
culated apical whorls, and the labral sinus at and not below the suture. 
Perhaps it would be advisable to employ the name Clathurella, proposed 
by Carpenter, as Defrancia was previously appropriated for another 
branch of the animal kingdom.
