In addition to these, other Memoirs will be arranged 

 for, on suitable types, such as Pagurus, Sagibta, Pontob- 

 della, a Cestode and a Pycnogonid. 



As announced in the preface to Ascidia, a donation 

 from the late Mr. F. 11. Crossage, of Woolton, 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 

 Mrs. Holt, Sir John Brunner, and others, are regarded by 

 the Committee as a welcome encouragement, and have 

 been a great help in carrying on the work.
