land M ( Andrew, Barlee, and J. G. J.). I observed a
specimen in Mr. Searles Wood's collection in the British
Museum mixed with P. tellinella, and marked " Coral-
line Crag " j Apulia (Philippi). Sars has recorded it
from Christ iansund, and Lilljeborg from another part
of the Norwegian coast; M fAndrew has dredged it
off Gibraltar, Madeira, the Canaries, Mogador,
Gulf of
Tunis, Algiers, Balearic Isles, and Pantellaria, at depths
Martin has taken it in
varying from 3 to 60 fathoms ;
the Gulf of Lyons ; Requien has enumerated it as a
Corsican shell ; Philippi described it as Sicilian ; "Coasts
of Greece (Graves and Spratt)," according to Forbes and
Hanlev. The number and extent of the localities above
mentioned on the authority of Mr. M fAndrew are proofs
of the energy and scientific skill with which his dredging
operations have been conducted throughout a great part
of the European seas. His tabulated results have been
of the greatest service to me in the preparation of this
work.
The animal is not less agile than that of P. telli/iella,
occasionally leaping like Donax vittatus and repeating
the action three or four times in succession. The shell
does not appear to attain quite the same size as the
other species ; my largest specimen is only half an inch
long
cors,
and nine-tenths of an inch broad.
Philippi at first gave this species
the name of P. dis-
but afterwards substituted that which had been
previously published by Turton.
