MAKINE BIOLOGICAL STATION AT POET ERIN. 237 



Norman, Brit. Assoc. Report on Shetland Dredgings, 

 1868, p. 279 ; = Argissa typica, Boeck, Crust. Amph. 

 Bor. et Arct. 1870. 



" A single male specimen was taken in the bottom tow- 

 net at Colwyn Bay in 2£ fath., Sept. 13th, 1898. 

 I have Dr. A. M. Norman's authority for saying that 

 his species is identical with Boeck's, and I have seen 

 the type specimen. Previously recorded from the Isle of 

 Man coast in 12 fath. 



" Gammarus duebeni, Lilljeborg.

 in Lough Doon, Co. Kerry, " about 1,000 ft. above sea- 

 level;" Mr. Thos. Scott records it from Loch Ruan, near 

 Campbeltown, "several hundred feet above sea level' 

 (Fifteenth Ann. Rep. of the Fishery Board for Scotland, 

 Part III., p. 322) ; and Prof. G. O. Sars says that it 

 occurs " in brackish pools among shore rocks, consider- 

 ably above high-water mark," and in "warm springs of 

 south Greenland." (Amphipoda of Norway, p. 503). 



" Pleonexes gammaroides, Sp. Bate. 



" Several specimens taken at Port Erin by Mr. Chad wick, 

 in April, 1898, probably in rock pools. Not previously 

 recorded in the Isle of Man." 



Mr. Arnold T. Watson, F.L.S., reports to me : — 

 " During the past year I have continued the observa- 

 tions on the habits of Owenia Jiliformis, to which 

 reference was made in the last Report, and 1 am now 

 working at one or two points which still remain unsettled. 

 In due course I hope to publish a full account, but mean-
