Miss Laura Florence, M.A., Aberdeen, to whom we referred 



Marine Algse; Miss Agnes S. Brown, Glasgow, who 

 ■ identified Copepods, which were submitted to her only 

 ! when the lists were in course of final revision; Mr E. 



Elmhirst, F.L.S., Millport, who named many of the Sponges ; 

 ! Dr J. F. Gemmill, Glasgow University, who looked over 



all the Polycha3ta preserved; Mr W. Gordon Pirie, Aber- 

 I deen, who identified several of the Polychseta at the time ; 

 \ Mr J. Macgregor Skene, Aberdeen, who worked out the 

 1 Polyzoa; Mr Alexander Patience, Glasgow, to whom we 

 f referred several of the Crustacea; Mr William Evans, 

 j F.E.S.E., to whom we are indebted for the identification of 

 f the Spiders, and for confirmation of the naming of Collem- 



bola ; Mr J. J. F. X. King, F.E.S., who named or confirmed 



all the Coleoptera ; and Mr Alexander Eoss, Glasgow, to

material was more completely examined during the winter 

 ] in the Zoological Laboratory of the Glasgow and West of 



Scotland Technical College, and in the Embryological
