cliannel he found numerous specimens of Mysis oculata, a form 
closely allied to M. inermis, and also Gammams cancelloides , 
but which differs from Gammarus in having the telson un- 
divided, and therefore in the Catalogue of Amphipoda of the 
British Museum has been placed in Pallasea, a genus founded 
on Gammarus cancellus, which was discovered by Pallas in 
Central Asia, and which is thought to be identical with Loven^s 
Scandinavian specimens. 
Hr. Sars found, in consequence of the force of the current, 
some difficulty in getting his dredge down; so that the greatest 
depth at which he obtained animal life was 200 fathoms, where 
the soil was a fine yellow mud; and here he obtained only a 
large lumbricous annelid, a few kinds of insect- larvae, and the 
following Crustacea : — 
VhyllrYpoda. A pus enneriformis, 
Cladocera. Sida crystallina, Simnosida frontosa, Simoceplialus vetulus, 
S. congener, Lathona setifera, Daplmella brandtiana, Holopediiim gib-

latus, Peracantlia truncata, Illyocryptus sordidus, Cliydorus globosus, C.

A short notice appears in the ^Annals and Magazine of Natural 
History^ for 186d, vol. xiv. p. 467, arid in the ^Archives des 
Sciences Phys. et Nat. Geneve^ for the same year, p. 84, on the 
previous researches of Hr. G. O. Sars on the Crustacea found in 
the neighbourhood of Christiania, in the years 1861-1862. 
The Bev. Alfred Merle Norman has drawn up (Transac- 
tions of the Tyneside Naturalists^ Field Club, vol. vi. p. 183) a 
Report of the Crustacea dredged off Seaham and Berwick, in 
connexion with a committee formed by the British Association 
and Tyneside Naturalists^ Field Club to dredge the coast of 
Northumberland and Durham, as well as the Doggerbank. 
The total number of Crustacea taken were sixty-three, of which 
Mr. Norman reports upon the Decapoda, Edriophthalma, and 
Sacculinidse, of which he gives a list. 
In the same general Report Mr. George S. Brady communi- 
cates the genera and species of the Entomostracous Crustacea
