compressed laterally than P. orbicularis, and the shells are distinctly 

 denticulate on the anterior margin and this differs from the typical P. 

 compresm as described in the Annals. The valves of the shells are white 

 and the surface polished. This appears to be a rare species and new to 

 Scotland. Two species of Ostracoda recorded from the Forth in the 

 monograph by Brady and Norman, viz., Argilloecia cylindrica, G. O. Sars, 

 and Pseudocy there caudata, G. O. Sars, were also dredged in the 1 Fluke

Habitat — In various parts of the Forth, from Inchkeith to May Island, 

 but not very common. It has been taken at Banff by Mr Edward ; at 

 Dunoon and Cumbrae, Firth of Clyde, by Mr Robertson; and amongst 

 trawled material near Eddystone Lighthouse by Messrs Bate and West- 

 wood. This species is easily distinguished by the peculiar form of the 

 hands of the second pair of gnathopods.

 Habitat. — Not unfrequent near May Island. In the Moray Firth, on 

 board the Messrs Johnston's steam trawler ' Southesk,' in February last, 

 a large dead cod-fish (partly decomposed) was brought up in the trawl-net, 

 and these Amphipods were observed by me in great numbers crawling 

 over, and burrowing in, the decomposing flesh of the dead fish. Mr 

 Robertson also records * that he found a ' partly broken test of Brissus 

 lyri/er crowded with this species,' which thus appears to be one of 

 those very useful organisms termed the scavengers of the sea.

 Marine Station ; dredged between Cumbrae Lighthouse and Arran, 50 

 fathoms ; Mull of Kintyre, in 49 fathoms, by Dr Murray ; and Cullercoats
