MARI-VE BIOLOGICAL STATION AT PORT ERIN. 29 



rear the eggs of the periwinkle (Littorina littored) 

 through the various stages of their development. Very 

 little success attended my efforts, and I made no progress 

 with the work. I hope to renew the attempt next 

 spring. I am able to add one species of Crustacea to 

 the Port Erin list and to the L.M.B.C. district. On 

 April 11th last, four specimens of Schistomysis arenosa, 

 G. 0. Sars, were taken in a small hand dredge dragged 

 lightly over the surface of the sand in the centre of the 

 bay. This species is known from the Ch'de area, from 

 several places on the Devonshire coast, and from 

 Blacksod Bay in the West of Ireland. As its name 

 implies, the species normally lives buried in fine sand." 



Professor Benjamin Moore and Mr. Edward 

 Whitley were engaged during the Easter vacation upon 

 an enquiry into the bio-chemistry of the reproductive 

 organs of EcJiinus, which was continued by Professor 

 Moore during the summer months, and a large amount 

 of material was accumulated and extracted in addition 

 to the work actually carried through at the Port Erin 

 Station. This material is now being utilised in tlie 

 Bio-Chemical Laboratory at the University of Liverpool 

 for the study of two distinct problems in metabolism by 

 Mr. X. G. S. Coppin, B.Sc, and by Mr. Alfred Adams, 

 M.B., Ch.B. 



Professor Moore reports : — 



"At the outset the purpose of the research was to 

 discover whether the reproductive organs of Echhius 

 esculentus contained any of those more simple represent- 

 atives of the protein classes, termed protamines and 

 histones, found by Miescher, Kossell and others in the 

 sperm of fishes, and by Matthews in another form of 

 echinoderm. A body closely resembling the arbacin of 

 Matthews was isolated and its properties studied both at 

 Port Erin and later at Liverpool.
