have not, as yet, been recorded in the L.M.B.C. lists, 

 were found on the shore — these were Ampliitrite jolinstoni 

 and Arenicola ecaudata. The latter species seems to take 

 the place of A. marina amongst stones and muddy shingle 

 where it is invariably found, while A. marina is confined 

 to the sand... The dredgings in June brought to light 

 several interesting animals, some of the more important 

 finds being : — Gratena olivacea, new to the Isle of Man, 

 and which has proved to be not uncommon in the upper 

 Coralline zone off Port Erin ; Embletonia pulchra, new to 

 the district, which during June and July appeared in almost

 fishermen as " Gilpins." These are chiefly young cod 

 and pollach — mostly the latter. Some were caught and 

 put into one the tanks, several are still alive and have 

 grown considerably since their capture... Towards the end 

 of the month the annual cleaning of the buoy took place. 

 This year there were several tubes and worms of what is 

 probably Sabella pen ic ill us .. .There were, as before, great 

 quantities of Caprellids, Ascidiella virginea and Ciona

 Una drummondi, Guthona aurantiaca, and Dendronotus 

 a)'bo)'escens...D\iimg the spring months, until towards 

 the middle of June, Aplysia punctata was one of the 

 commonest animals in the bay. It came up in quantities 

 in the dredge, it was to be found commonly on the shore 

 amongst rocks, and after a westerly wind the shore was
