MARINE BIOLOGICAL STATION AT PORT ERIN. 23 



of organisms, especially of (Jopepoda, was noticed about 

 the middle of July and from that time onwards to the end 

 of September. I saw only three specimens of Aurelia 

 aurita, usually so abundant, within the limits of the bay 

 during the summer, and Beroe ovata, abundant in July 

 and August last year was not seen at all. 



" I have a few corrections to make in the list I gave 

 in last Report : — The Siphonophore recorded last year as 

 Agalmopsis elegans has been identified by Mr. E. T. 

 Browne as Cupulita sarsii. It has been less common this 

 year than last. The Ctenophore recorded as Hormiphora 

 proves to be Pleurobrachia, and that recorded under the 

 latter name is, I find, Bolina. The only addition to the 

 Plankton Fauna is Arachnactis albida, of which the near 

 relative A. bournei was recorded last year."

Dredging Expeditions. 



Many dredging, trawling, and tow-netting expeditions 

 have taken place in sailing boats, larger rowing boats, 

 and our own " Shellbend " punts in the immediate 

 neighbourhood of Port Erin throughout the year, and the 

 results have been recorded by the Curator in the distri- 

 butional charts referred to further on (see p. 39). Boat 

 collecting expeditions at time of spring tides from Port 

 St. Mary to the Great Caves at the Sugar-loaf Pock and 

 to the " Clets " in the Calf Sound, have also been carried 

 out with success. 



On September 13th we hired the steam trawler " Rose 

 Ann" from Mr. Knox, of Douglas, and had an excelleni 

 day's work, chiefly to the east and south of the Calf Island, 

 dredging and trawling in depths of from 15 to 30 fathoms. 

 All the workers at the Station joined in the expedition. 

 It was a beautiful day at sea. We worked hard all day,
