SOUTH AFRICAN MARINE MOLLUSKS. 205
Family TELLINIDAE.
Genus TELLINA Linnaeus.
TELLINA VIDALENSIS Sowerby.
Cat. No. 66, U.S.N.M., four specimens collected by William
Stimpson on the North Pacific Exploring Expedition in False Bay.
TELLINA ALBINELLA ALFREDENSIS, new subspecies.
Plate 46, figs. 7, 8.
Shell similar in outline and coloration to the rose-colored form of
T. albinella Lamarck, but differing from it in being much heavier,
and in having the angulated posterior dorsal area much narrower,
which renders the posterior end of the shell much more pointedly
beaked. The radiating sculpture is also much coarser than in
albinella.
Cat. No. 186948, U.S.N.M., contains the type which comes from
Port Alfred (Coll. No. 318). The type measures: Length, 46.8 mm.;
altitude, 25.5 mm. Cat. No. 249859, U.S.N.M., contains another
valve from the same locality (Coll. No. 1131).
TELLINA NATALENSIS Krauss.
Cat. No. 186949, U.S.N.M., one valve from Port Alfred (Coll. No.
319).

National Museum, all from Port Alfred, as follows: Cat. No. 186950,
two specimens (Coll. No. 320); Cat. No. 249860, three specimens
(Coll. No. 1132); Cat. No. 249885, three very young specimens (Coll.

TELLINA, species?
Cat. No. 251037, U.S.N.M., is a young valve of a Tellina which I
am unable to identify, from Port Alfred (Coll. No. 1554).
TELLINA, species ?
Cat. No. 251050, U.S.N.M., is a valve from Port Alfred, belonging
to the section of rounded-valve Tellinas having radiating red bands,
which I am unable to identify. On account of its worn condition I
refrain from describing it as new (Coll. No. 1367).
