classify the forms according to their natural affinities. It is rarely that monographers
and artists take such laudable pains to supply the wants of students. In the monograph
of Galeomma and Scintilla, however, the locality-marks have not been observed to a
single species, except the " British G. Turtoni " and its " Philippine analogue, G. macro-
$cki.<tma i Desh." This is the more remarkable, as most of the species were described by
Desh., with localities, in P. Z. S. 1855, pp. 167-181.
ON MOLLTJSCA OP THE WEST COAST OF NORTH AMERICA.
In the ' Malacological and Conchological Magazine/ by G. B. Sowerhy,
London, 1838, is a monograph of Leach's genus Margarita. The following
probably belong to the N. W. Coast, and are figured in the Conch. 111. ;
25. Margarita striata, Brod. and Sby. Boreal Ocean.
20. Margarita undulata, Sby. Arctic Ocean.
26. Margarita costellata, Sby. [Non Brit. Mus. Col. = M. pupilla, Gld.; differs in
having the interspaces of the spiral ribs decussated. Arctic Ocean.]
26. Margarita acuminata, Sby. Arctic Ocean.
30. Aphrodite columba, Lea, = Cardium Grosnlandicum.
Several West Coast species were named and figured in the elder Sowerby's
'Genera of Recent and Eossil Shells,' London, 1820-1824 ; a work of singular
merit for its time, but left unfinished*. The stock was purchased by a dealer,
with a view to completion ; but newer works have occupied its place, and
the valuable plates and text remain useless in his hands. As no dates appear
in the bound copy of the work, it cannot be stated whether the species here
named by Mr. Sowerby had been before published. The loss of the original
work has been in some respects supplied by the completion of the extremely
similar ' Conchologia Systematica/ by L. Eeeve, vol. i. 1841, vol. ii. 1842.
It might almost be considered a second edition of the ' Genera,' of which
some of the plates occur in the quarto form. References are here given to
the species reproduced from Sowerby's unfinished work, which is often quoted
by Mr. Reeve according to the " Numbers " in which it appeared :-

late years been made in the principal authority, viz. the Cumingian collection. By the
redistribution of species into the modern genera, the student is greatly aided in his search
for special forms ; but, for the sake of uniformity, the autograph labels of collectors or
describers of species are generally rejected, the names being either in the handwriting of
the clerk or from the printed index in the monograph, and rep resenting only the judg-
