animal in the tank capable of doing this, I did not disturb 

 it, and found, on the following morning, that it had been 

 disturbed and re-buried. The next morning nothing 

 remained but the chelae and walking legs. The lobster 

 has now established itself in a particular crevice in the 

 rock- work, to which all food given to it is carried. 



"In February I was fortunate enough to see a large 

 number of ova extruded by a specimen of Nereis pelagica. 

 I kept the worm in a small dish, and one day noticed that 

 the parapodia on the left side of the ninth and tenth 

 segments had become much swollen. On the next day 

 the swelling had increased, and while watching the move- 

 ments of the worm I saw the ova extruded from the 

 swollen region, probably from the nephridiopores of the 

 affected segments. I then fixed and preserved the worm, 

 and it has since been photographed by Mr. E. Schuster, 

 of New College, Oxford. 



"In regard to Faunistic work, I have availed myself of 

 every opportunity afforded by low tides to collect on the 

 shores of Port Erin and the neighbouring bays, and 

 thirteen dredging excursions have been undertaken in 

 small boats. The courses dredged over, and the animals 

 collected, were carefully recorded. The harbour buoy was 

 brought ashore for its annual cleaning on August 11th this 

 year, and again yielded over thirty species. Amongst 

 them was an abnormal specimen of the Nudibranch, Eolis 

 glottensis (?), in which the foot is divided into two quite 

 distinct portions of exactly similar shape, one in front of 

 the other. Amongst the additions to our lists are the 

 Hydroid Campanulina repens, and the Nudibranch Her- 

 mcea dendritica, both discovered in ' Pat's Dub ' by Miss 

 Sollas. 



" I have devoted some time during the past year to the 

 study of the Polychaeta of the bay, and have gained a
