In addition to these, other Memoirs will be arranged 

 for, on suitable types, such as Pagurus, Sagitta, Pontoh- 

 della, a Cestode and a Pycnogonid. 



As announced in the preface to Ascidia, a donation 

 from Mr. F. H. Gossage, of Wooltoii, met the expense 

 of preparing the plates in illustration of the first few 

 Memoirs, and so enabled the Committee to commence 

 the publication of the series sooner than would otherwise 

 have been possible. Other donations received since from 

 Mr. Gossage, Mrs. Holt, Sir John Brunner, and others, 

 are regarded by the Committee as a welcome encourage- 

 ment, and have been a great help in carrying on the work.
