lu addition to these, other Memoirs will be arranged 

 for, on snitable types, such as S<igitta, a Cestode (by 

 Mr. vShipley), Pac/uius, and a Pycnogonid. 



As announced in the preface to Ascidia, a donation 

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

 of preparing the plates in illustration of the first few 

 Memoirs, and so enabled the Committee to commence 

 tiie publication of the series sooner than would otherwise 

 have been possible. Other donations received since from 

 Mr. Gossage, from Mrs. Holt, aud from others, are regarded 

 by the Committee as a welcome encouragement, and have 

 been a great help in carrying on the work.
