In addition to these, otlier Memoirs will lie ari'finged 

 for, on suitable types, sucli as Sayitta (by Mi-. Cole), a 

 Cestode and a Turbellarian (by Mr. Shipley), Carcinus, 

 an Aniphipod, and a Pycnogonid (probably by Dr. A. 11. 

 •lackson). 



As announced in the preface to Ascidia, a donation 

 from Mr. F. H. Gossag'e of AVoolton met the expense 

 of preparing' fjie plates in illustration of the first few 

 Memoirs, and so enabled the Committee to commence 

 the publication of the series sooner than would oiherwise 

 have been possible. A second donation received since 

 from Mr. Crossage, and another recently from Mrs. Holt, 

 are regarded by ihe Committee as a welcome encouragi'- 

 ment, and will be a great help in carrying on the work.
