L.M.B.C. Memoirs. 



During 1909 no less than three Memoirs have been 

 issued: — No. XVII, Pecten (the Scallop), by Mr. W. J. 

 Dakin, M.Sc. ; No. XVIII, Eledone (the local 

 " Octopus "), by Miss A. Isgrove, M.Sc. ; and No. XIX, 

 on Polychaet Larv.e (the young stages of the Higher 

 Worms) at Port Erin, by Mr. F. II. Gravely, M.Sc. 

 Doris, the sea-lemon, by Sir Charles Eliot, and other 

 Memoirs are also far advanced; and we hope to have a 

 Memoir on our Irish Sea species of Ceratium and other 

 Dinoflagellata from Prof. C. A. Kofoid, who did some 

 work on our local material during his visit to our labora- 

 tory in 1908. This unusual amount of excellent material, 

 which the Committee is happy to be able to issue to the 

 scientific world, is, however, embarrassing from the point 

 of view of expense. Lithographic plates, such as these 

 Memoirs require, seem to become more costly, and with 

 the growing elaboration of the subject more detailed 

 illustration is necessary. The Committee are therefore 

 always very grateful for special donations and grants 

 which have in the past enabled the Treasurer to meet the 

 expenses of plates for several of the above-mentioned 

 Memoirs. Further donations to provide for the illustra- 

 tions of those still unpublished will be very welcome.

 published or arranged for : —
