On the iVIollusca procured during the 'Lightning' and 

 'Porcupine' Expeditions, 1868— 1870,— By John Gwyn 

 Jeffreys, LL.D., F.R.S., F.G.S., h.c. Pro. Zool. Soc, April, 1878. 



These cruises were made under the auspices of the 

 Royal Society, in the North Atlantic, and in the Mediterranean 

 Sea. Eight dredgings were made in the 'Lightning' expedition, 

 and about 100 in the two cruises of the 'Porcupine.' 



Twenty-two species of Brachiopoda are enumerated of which 

 four are described as new — Terebratula tuberata (PI. xxii, f. 2) in 

 North Atlantic in 795 fathoms. T. trigona (PI. xxii, f 3) off the 

 coast of Portugal in 500 fathoms. T. siibquadrata (PI. xxii, f. 4) 

 off the coast of Portugal in 500 — 600 fms. Rhynchonella sicula 

 Seguenza MS., (PI. xxii, f 5, 6) English Channel in 690 fms. 



A very elaborate series of tables are given showing the stations 

 at which dredgings were made, with the temperature, and the 

 depth in fathoms. 



A table is also given of the European species of the group, 

 giving the range of each species in depth, and also the locaUties 

 where they are found fossil. 



Dr. Jeffreys also expresses the opinion that Waldheimia and 

 Terebratulina should not be considered distinct genera as Mr. 

 Davidson has suggested.
