MARINE BIOLOGICAL STATION AT PORT ERIN. 81 



Memoir. Still others are in active preparation. We 

 frequently receive, from heads of laboratories, suggestions 

 of types that it would be useful to get undertaken, and, 

 from naturalists, of Memoirs that they are willing to 

 write. As I remarked last year 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 very grateful to those friends who 

 have kindly by special donations enabled the Treasurer to 

 meet the expenses of plates for several of the above- 

 mentioned Memoirs. Further donations towards the 

 illustrations of those still unpublished will be very 

 welcome.
