192 CRUSTACEA.
other rather marine forms to recent immigration from the sea
upwards, but thinks that they have remained from the old times
when this soil was part of the sea. The said species are all
found by dredging, and not on the surface of the water. The
localities are exactly described; and in the introductory remarks
the principal Ostracoda of salt marshes and of estuaries are also
named; in the latter marine and freshwater species are mixed.
A list of 84 species found in the river-estuaries of England and
Scotland, and another of 99 from the English Fen-district and
Holland, terminate the paper. Ann, N. H. (4) vi. pp. 1-33.
Black Sea. The Crustacea are reviewed by CZERNIAVSKI in a
somewhat long paper written in Russian; most of them are
identical with Mediterranean species—as, for example, Stenorhynchus
longirostris, Pilumnus hirtellus, Eriphia spinifrons,
Pachygrapsus marmoratus, Diogenes varians, &c. The author
has made his observations at Jalta, on the south-eastern coast of
the Crimea : he enumerates 80 species, 71 of which have been observed
in about 150 square fathoms on stones in a depth of under
5 feet, in the months of June and August (old style). Seven
other species have been obtained with the surface-net of J. Miiller;
only two species, Portunus holsatus and Callianassa subterranea,
have been observed in a greater depth than 5 feet. The
author is inclined to think the Black Sea much richer in Crustacea
than the Belgian shores, and even the British seas.
Another list of Crustaceans found in the Black Sea, containing 55 species,
some of which are new, but not described, is given by F. Marcusen in the
same journal, pp. 177, 178.
Twenty-nine species of Ostracoda found in various depths, from 10-250
fathoms, in the Gulf of St. Lawrence are enumerated by Brady, I. c. pp. 450-
454; some new or remarkable species described and figured. He has also
described in Berchon and Folin's ' Fonds de la Mer ' others from the West
Indies, p. 191; the Cape- Verd Islands, p. 192 ; Pulo Pinang, p. 194; the Straits
of Macjellan, pp. 198-202.
America. A few Brazilian Crustacea are mentioned in the very prolix
description of the Imperial and National Museum at Rio Janeiro, published
by L. Netto, pp. 305-307.
Forty species, most of them new, are described, eight from Central America,
Peru, &c, by Sid. Smith, Tr. Conn. Acad. ii. pp. 113-174.
