Contrarv to expectation there was no difference in 

 height between shells taken from the more exposed and 

 the more sheltered places, if taken at the same water 

 level. The two sides of the Port Erin breakwater served 

 as splendid collecting' grounds for material for this 

 purpose. 



Mr. H. G. Jackson, B.Sc, in addition to giving 

 me some assistance in taking the observations and 

 plankton gatherings at sea during the Easter vacation, 

 started an investigation of the complete anatomy and 

 histology of Pagnrus hernhardus, the Hermit Crab. Mr. 

 Jackson is now continuing that work during the winter 

 in the Liverpool Laboratory, and the results will be 

 published, when completed, as an L.M.B.C. Memoir. 



Professor F.J. Cole, with two members of the Staff, 

 Mr. n. L. Hawkins and Mr. A. H. Malpas, and three 

 of his senior students from University College, Reading, 

 worked at Port Erin during the Easter vacation. 

 Professor Cole writes to me, as follows, in regard to their 

 work : — 



" The visit to Port Erin, last Easter, of our College 

 party of six was partly for educational and partly for 

 collecting purposes. The College has now provided for 

 the Easter class in the estimates, so that it will now 

 become an annual event. Its importance and popularity 

 with the students are too manifest to be dwelt upon, and 

 we expect to have a larger ])arly Axoiking ai llie Station 

 next Easter. We were able this year to add two species 

 to till' local i'duua— Nereis rirens, from Port Erin Bay, 

 and a ])eculiar Rhizoce])hal()ii , related to Peltogaster, 

 but still undetermined, wliicli was found parasitic on a 

 large Gahif/icti. AVt' hiougiit hack a (|uantity of material 

 for the Museum, including a number of successful 

 injections of Echiuoderms, Eledone and Fishes."
