0) MARINE SHELLS OF SOUTH AFRICA. 
The longitudinal flames are rather broad, distant and 
irregularly waved on the back of the shell, not (as in F. 
cavica) marking the periods of growth. 
1 have only seen two specimens of this species, both 
collected at Port Elizabeth. They are about equal in size. 
Fusus CRENULATUS, Sowerby, Thes. Conch., vol iv., 
p. 85, pl. 14, fig. 170.—-Cape of Good Hope. 
Tryon opines that this is a Siphonalia, but in the absence 
of evidence, I think it best for the present to place it with 
Fusus. 
Euturia Macevrant, Vélaim, Arch. Zool. Exper. et Gen. 
1877, vol. vi., p. 104, pl. 2, figs. 8-11.—Natal. The type is 
from St. Paul’s Island. 
PISANIA TRITONOIDES, feeve. (Buccinum), Conch. Icon. 
sp. 77.-—Cape of Good Hope (Gould). Durban. 
MeETULA CLATHRATA, Adams and Reeve, Voy. Samarang,

PLEUROTOMA TIGRINA, Lamarck, Reeve, Conch. Icon. 
(Pleuvotoma) fig 3.—Durban. Common in many localities 
from Mauritius to the Philippines and South Sea Islands. 
PLEUROTOMA CINGULIFERA, Lamarck, Reeve, Conch. Icon. 
fig. 1.—Durban. Distribution about the same as the last. 
PLEUROTOMA MONILIFERA, Pease, Proc. Zool Soc. 1860, 
p- 398. Tryon, Man. of Conch. vol. vi, p. 173, pl. 4, fig. 52 
(as var. of P. gemmata, Hinds). 
Prieurotoma (Drituia) Lavarpi, Sowerby, n. sp. pl. 8, 
fig. 3, 4. Testa turrita, rufo-fusca, levigata, longitudinaliter 
costata; anfractus 7 obtusissime angulati, supra angulum 
leviter concavi, infra convexiusculi, costis circ. 11 rotundatis 
levibus, obliquiusculis instructi; ultimus spiram  fere 
aquans ad basin leviter alternatus haud rostratus, spiraliter 
tenuisulcatus; apertura ob’ongo-ovata; columella rectius- 
cula superne valde callosa ; labrum arcuatum, sinu latiusculo, 
haud profundo emarginatum. 
Long 11, diam 4 millim. 
Hab. Pondoland. Port Elizabeth. 
This species has long been mistaken for P. castanea Reeve, 
but upon compariscn with the type of that species it is 
found to be quite distinct,
