xxii. pp. 202. 
The third part of P. Strobel’s “Materiali” {suprd^ p. 135) contains 
aln extended physico-geographical account of the Southern Argentine 
States, and a plate representing the new species of land-shells described 
in the first part*

A notice of recent general works on deep-sea soundings, containing 
also conchological particulars, in “ Les explorations sous-marines,” by 
J. Girard, Paris: 1874, 8vo, 248 pp. with numerous woodcuts. 
1 . Northern and Western Seas of Europe, 
A list cf 190 sea-shells (including 5 Brachiopods) dredged on the 
coast of Norway, chiefly in the arctic zone, including some new species, 
is given by T. A. Yerkruzen, JB. mal. Ges. ii. pp. 229-240, pi. viii. 
Scotland. W. C. Macintosh enumerates 73 species of Bivalves, 1 
Dentalium, 94 Gastropods, including 27 Nudibranchiates, and 4 Cepha- 
lopods, observed by himself at St. Andrews; of these may be men- 
tioned Lima subauriculata and loscomhi, Tellina pusilla, Fsammobia

Ninety-seven species of Bivalves, 3 of Solenoconchce, 95 of Gastropoda', 
and 2 of Cephalopoda, collected in various parts of the North Sea during 
the expedition of the German steamer ‘ Pommerania,’ are enumerated 
by A. Metzger, Bericht &c., pp. 230-252 ; a few new species are 
described, with notes on varieties and occurrence of others, pp. 252-261. 
The conchological fauna of the northern part of the North Sea, north 
of the Dogger Bank, is much richer, numbering about 144 Gastropods 
and 107 Bivalves, that south of the Dogger Bank only about 59 Gas- 
tropods, and 79 Bivalves; the separating line between both may be 
traced from Scarborough to the Skagerrak. A channel of deep water 
going round the coast of Southern Norway, contains mere northern, 
even arctid species ; id. tom. cit. pp. 262 & 263. 
Shells dredged at the Dogger Bank in 7-50 fathoms, at least 20 
miles from land, are enumerated J. Leckenby and J. T. Marshall, 
Ann. N. H. (4) xyi. pp. 390-334. 
Several marine species are found only as dead shells in the more 
southern part of the North Sea, south of 60° N. lat., e.g., Pecten islandicus 
(L.) and Astarte borealis (Chemn.) ; A. Metzger, 1. c. pp. 263 & 254.
