J. Gwyn Jepfreys’s lecture on Deep Sea Exploration, London,

Nadir, mal. Ges. 1881, pp. 63-57. 
Gwyn Jeffreys continues and finishes his discussion of the bivalve 
Mollusca procured during the ‘Lightning' and ‘Porcupine' expeditions, 
1868-1870, in the Atlantic and Western Mediterranean ; he enumerates 
19 species of Kelliidve, 16 Lucinidee, 3 Carditidoe, 12 Cardiida;, 1 Chama, 
11 Astartidee, 15 Veneridee, 21 Tellinidoi, 14 Mactridoi, 6 Sole7iidce, 12 Pan- 
doridcCj 5 Anatinidce, 25 Coi'hulidce, 2 Myidce, 2 Saxicavidee, and 2 Phola- 
didoi, among which are 33 new species. It is to be regretted that the 
localities and depths of them are not expressly stated, but only indi- 
cated by the numbers of the stations, without corresponding explanation 
in the same paper. The author adds, however, many very valuable notes 
on the general distribution, varieties, and synonomy of most of the 
species, and also much new information concerning their mode of life.
