them. The introduction gives a careful account of authors who have con- 
tributed to the knowledge of the Danish sea Mollusca, and of dredgings made 
in these seas by various naturalists. Vid. Medd. 1871, pp. 167-226. 
Several shells of the Baltic (including Litorina litorea) are mentioned as 
found during an excursion to the inlet of Wismar by Struck, Arch. Ver. 
Mecklenb. xxiv. pp. 69-71. 
Astarte arctica (Gray) is recorded by Wiechmann {ibid. p. 71) as again 
found near Warnemiinde. 
Bergh gives a list of 62 spp. (29 Bivalves and 33 Gastropods) collected on 
the banks of the Kattegat and Skagerack, at depths of 10-30 fathoms, and of 
13 spp. found on the Skag-bank, on the western side of Jutland, in 8-11 
fathoms. Among them 11 belong to the arctic, 31 to the boreal, and 18 to 
the Lusitanian fauna. Act. Lund. vii. pp. 13-23, 28-36. 
33 marine Gastropods and 19 Bivalves, collected during an excursion of the 
Belgian Malacological Society at Heyst, are enumerated by Mourlon, Ann. 
Mai. Belg. v. pp. 69-73, 
84 spp. observed at St. Malo and Roscoff, in Northern France, are enume- 
rated by Grube, JB. schles. Ges. pp. 61-63. 
Tasle publishes a supplement to his (1868) list of Mollusca of Western 
France {cf. Zool. Rec. vi. pp. 619 and 628), adding many spp., chiefly Nudi- 
hranchiata, . 
Fischer’s supplement to his marine conchological fauna of the Gironde 
■ (1865) brings the number of spp. from 177 to 347, including those observed at 
Rochelle, many of which are due to the researches of Lafont at Arcachon, and to 
the dredgings of De Folin. Six-sevenths of the spp. are common to England 
and the Mediterranean j 17 boreal, not ranging further south than Gape 
Finisterre, in Portugal ; and 31 meridional, not ranging further north than 
Cape Finisterre, in Brittany. Ostrea cochlear (Poli) and JDiphyllidia pustu- 
losa (Schultz) are here recorded as new to the Atlantic coasts of Europe. 
In the introduction, the currents, depths, banks, and accumulations of shells, 
near or on the coast, are briefly mentioned. Act. Soc. L. Bord. xvii. pp. 
71-132. 
4 spp. of Bivalves, 9 Nudibranchiata, 18 of mostly minute shell-bearing 
marine Gastropods, and as many Oephalopods, observed at Arcachon (several 
new) are enumerated by Lafont, ibid, xxviii. pp. 266-278. 
The list of the recent fauna of the South -European seas has 
been enriched by various spp. hitherto known only in a fossil 
state (e. g. Trochus filosus, T. suturalis, and Pleurotoma hispU 
dula), or from Norway or North America, and several quite new, 
through the deep-sea researches of Carpenter and Jeffreys.

Hidalgo has published three more parts of his Molluscos marinos de 
Espana,” &c., the second and third of which contain (according to Crosse, J. 
' de Conch, xix. p. 153) the Bivalve genera Lutraria, Eastonia^ Callista, 
JDosima, and Caryatis, and some EuUidcc j the fourth is said to be a monograph 
of the genus Fasciolaria. 
93 spp. of sea-shells, collected on the Mediterranean shore of Egypt, near 
Ramleh, are enumerated by Schneider, SB. Ges. Isis, 1871, pp. 116-121.
