Wrio'ht, a keen observer and enthusiastic Avorker in Marine 

 Zoology. 



In May of this year Mr. E. Sharp (one of our junior 

 members) found a specimen of Anilocra mediterranea on some 

 rocks in Bordeaux Bay. This sea-louse is usually parasitic 

 on the Corkwino- and other species of rock-fish {vide Mr. 

 Sinel's paper on Fishes, Transactions, 1905, p. 61). 



Mr. Wright has found several -specimens of Pirimela 

 denticidata on the shore ; this pretty but little known shrimp 

 is stated in Bell's Crustacea to be rare, and to live only 

 in deep water. Jlippolyte thompsoni and My sis chameleon 

 are two rare deep watc* shrimps found in July of this year. 

 The Bev. Canon Norman, a great authority on Crustacea, 

 visited the Island during the summer, and identified a large 

 shrimp, which Av^as caught some time ago, as Pandalv.s 

 annulicornis (= P. montagui) or the ^Esop Shrimp, This 

 is believed to be the first record of the occurrence of this 

 species in the Channel Islands. 



At the beginning of July a specimen of Porbeagle 

 Shark {Lamna cornnhica ) over three feet long, w^as caught 

 by a local fisherman ; and about the same date, a specimen 

 of Electric Bay ( Torpedo rvU/aris) was found. 



It has long been known that starfishes are serious enemies 

 of the Ormer, and on Oct. 16th Mr. Wright Avas able to observe 

 a starfish kill and partly eat an Ormer in his aquarium. 



On Jan. 13th Mr. E. Sharp brought me three specimens 

 of the large sea-slug EoJis triangnlata, and I put them in my 

 aquarium. Xext day I found an 0])elet Anemone {Anthea 

 cereus) with all its tentacles bitten off to Avithin a quarter 

 of an inch of the disc. We Avere able, by Avatching the 

 actions of the Eolis, " to catch it in the act," and condemn it 

 as tht; culprit. The Anemone died, and we afterAvards noted 

 that the locality to the south of the Castle Breakwater where 

 the Eolis is common, Avas destitute of Anthea cereus, though 

 the species is exceedingly common just the other side of 

 the breakwater. The sea-slug seemed absolutely immune to 

 the usually deadly tentacles of the anemone. 



My experiments on the movements of limpets have been 

 left unfinished, and I give some account of my present results 

 in the hope that some member may continue the research. 

 I have found great differences in the behaviour of different 

 individuals Avhich do not seem to be easily explained. I give 

 tAvo cases as examples. 



On April 23rd I marked a limpet and moved it two 

 feet horizontally from its '' home," the intervening rock being
