MARINE BIOLOGICAL STATION AT TORT ERIN. 31 



On dead shells (mostly Pectuncidus glycimeris) trawled 

 at 6 miles S.E. of of Calf Island, 30 fathoms, on September 

 13th, were found the following Polyzoa —

 branacea, Smittia reticulata, S. trispinosa, S. cheilostoma, 

 Microporella ciliata, M. malusii, Diastopora obelia, D. subor- 

 biadaris, Stomatopora joJnistoni, S. major, S. expansa, 

 Lichenopora hispida, Chorizopora brongniartii, Aetea recta,

 on the Higher Crustacea from the Biological Station, 

 Port Erin, received September 26th, 1900 " : —

 from low tide at Calf of Man, on September 11th. Of 

 the four species in the first bottle, two have not been 

 previously recorded, viz., Gnathia dentata, Sars, two 

 females, and one fine specimen of Iphimedia eblance, Hate. 

 The former of these has not to my knowledge been pre-

 agreeing exactly with Gr. O. Sars' excellent figure in the 

 Isopoda of Norway, I have considerable hesitation in 

 recording it in the absence of the male. 



Among Professor Herdman's low-nettings after dark 

 in Port Erin Bay the only species calling for remark is 

 Schistomysis spiritus (Norman), which has only been 

 recorded before from Puffin Island. This night-gathering
