MARINE BIOLOGICAL STATION AT POUT ERIN. 31 



were taken ; while grey Mullet (Mugil chelo), Turbot 

 (Rhombus maximus), and a fish rather mysteriously 

 referred to as " Salmon-trout " made up the catches in 

 small and varying numbers. The Saithe, locally known 

 as " Bloghan," is extensively fished with rod and line, 

 and the occurrence of fine and calm evenings at the time 

 named favoured good sport. The " back " herring fishery 

 appears to have been more than usually successful this 

 autumn, and it is worthy of note that on the East side of 

 the Island the capture of the fish involved the destruction 

 of an enormous quantity of spawn. 



" I have continued my investigation of the fauna of 

 Port Erin Bay by collecting, at frequent intervals, on all 

 parts of the beach and by occasional dredging excursions. 

 The Nudibranch Galvina cingulata and the Crustacean 

 Athanas nitescens are now recorded for the first time, the 

 former having been taken in December, 1900, and the 

 latter in March, 1901. Polycera lessoni was also found, 

 on June 18th. Two specimens of the beautiful little 

 Polychsete Gattiola spectabilis were found in a rock pool 

 early in February. This worm has not come under obser- 

 vation for some years past. I have devoted a good deal of 

 time to the study of the Compound Tunicates, and have 

 made some careful drawings for Professor Herdman of a 

 number of representative species. Mr. P. Nevill kindly 

 sent some Compound Tunicates and other animals, 

 obtained by diving, from below low-water mark at the 

 Battery Pier, Douglas. 



" The Plankton fauna of the bay has resembled that of 

 former years. Noctiluca occurred very sparingly in one 

 tow-netting taken on January 11th, and in several taken 

 in August. It is remarkable that this widely distributed 

 organism should have been observed in enormous numbers*
