"A series of experiments on the method of feeding in 

 Lamellibranchs was begun, to show in what manner the 

 gills exercised the function of collecting food material 

 and the labial palps of discriminative selection of food 

 particles. I hope to be able to give the results of these 

 experiments after further observations. 



"I also procured at the Station specimens of Opistho- 

 branchs which will form material for future work." 



The Rev. T. S. Lea (who has kindly presented a 

 large ordinance map, 6 inches to the mile, of the S.W. of 

 the Isle of Man, to the Biological Station) has continued 

 this summer his series of observations upon the zones of 

 algae on the shore, and has taken a number of photographs 

 of species in situ on the rocks and in pools. 



The work done by Mr. Browne and by Mr. Beaumont 

 at the Station is sufficiently dealt with in their reports, 

 upon the Medusae and the Nemertea respectively, w T hich 

 have now been published in Vol. IV. of the "Fauna." 

 Mr. Walker and Mr. Thompson have discussed the results 

 of their w T ork on Crustacea some pages back (p. 10) ; 

 and the investigations of Prof. Boyce and Prof. Herdman 

 on oysters under various normal and abnormal conditions 

 is work of a very special nature — partly bacteriological 

 and partly experimental — which is still in progress, and 

 will be reported upon in full to the British Association 

 and to the Lancashire Sea-Fisheries Committee. 



In a brief report from the Curator giving an outline of 

 the w T ork of the summer the following observations 

 which seem worthy of permanent record occur : — " The 

 dredgings in May produced amongst other nudibranchs 

 Cuthona arenicola, new to the fauna round the Isle of 

 Man ; and two Polychaetes, which though common here
