 amongst the ])lankton. Five coastal areas were examined, 

 also three off-shore stations and Port Krin Hay. Tlie 

 distribution of many of the oi'ganisnis had now l)ecome 

 fairly nnifonn. Diatoms were piesenl in every area 

 except Carnarvon Bay, and were re])i'esen1e(l by

 mentioned, but nowhere else. 'I'wenty-nine organisms, 

 including the eggs of ten species of fish, Avere noted from 

 Port Erin in April. 



The tow-nettings taken in May numbered ten, and 

 c()m])rised four collections from the Fishery Othcers, and 

 three surface and three bottom gatherings made by the 

 steamer. The organisms represented in the material, 

 including the eggs of four species of fish, reached a total 

 of thirty-one. Nine species of Copepoda were noted. Of 

 these, (' critrojKUic^i liamafus, ('. fyincuH, Acarf/a rhnisi 

 and A. <H^(<niihit<i were the most abundant: the last 

 two ill some cases forming the bulk f)f the material 

 collected. Post larval pleuronectids were less numerous 

 than in April, and young gadoids made their appearance 

 for the first time. The presence of gelatinous alga:! 

 interfered to some extent with the working of the tow-nets 

 in three of the other coastal areas investigated, and pro- 

 bably had some connection with the abnf)rmal results. 

 At Blackpool only Fhurohyarhid and this alga were 

 noted. The collection from Port Erin on ^lay 11th was 

 also rather remarkable. It was practically a gathering 

 of Chaetoceros. 



In June twelve collections were made, of which four 

 were from near the bottom. (jelatinous alga- had by this
