Mollusks

_P. violacea._ The violet Psammotæa. Pl. 7, fig. 5.

Transversely ovate-oblong, sub-ventricose; transversely striated; purple
radiations.


                       TELLINARIA. Seven genera.

The first five of these genera have one or two lateral teeth, the
remaining two have none.


              4. Tellina. The Tellen. Fifty-four species.

This genus differs but little from the Donax; its species are numerous,
especially in the seas of hot countries; they are found sunk deep in the
sand.

There are but few genera that can vie with the Tellina in beauty,
variety, or number; some are smooth and polished, some are remarkable
for their beautiful radiations, and others are covered with minute striæ
and undulations; occasionally the whole surface is covered with
imbrications or scales.

They are produced abundantly in almost every sea and in many rivers, but
the finest species are found in the pearl-fisheries of Ceylon.

The usual form of the Tellina is broad at one end and gradually tapering
towards the other. It derives its name from the Greek word τελειω, to
bring to a termination.

Shell of variable form, generally striated longitudinally and very
compressed; equivalve, more or less inequilateral; anterior side longer
and more rounded than the posterior; offers a flexuous plait or twist at
the inferior margin; summits little marked; hinge similar; one or two
cardinal teeth; two distant lateral teeth, with a pit at their base in
each valve; ligament external.

                            Tellina radiata.
