preparation of volume II. of the catalogue of Welwitsch's 

 Angolan plants. Many new species have been described 

 belonging to genera of those tribes, and are now ready for 

 publication. He has also prepared for publication the 

 material collected by Welwitsch belonging to the orders 

 Hceviodoraceoe, Iridacece, Amaryllidece and Taccacece. He 

 has worked out the Monocotyledons, and the apetalous and 

 some gamopetalous Dicotyledons of the collections made by 

 Mrs. E. Lort Phillips in Somaliland, prepared a list and pub- 

 lished the new genera and species ; and has also worked out a 

 small collection of plants from the Philippine Islands, collected 

 by Mr. John Whitehead. He has given some time to the order 

 Palraece, re-arranging one of the Palm Cases in the public 

 gallery, and also revising the genus Plectocomiia. He has also 

 commenced the re-arrangement of the Orchids in accordance 

 with Dr. Kranzlin's monograph of the order now in course of 

 appearance. The plants of the following collections have been 

 selected, laid out and incorporated with the Herbarium. Europe 

 (Dbrfier) ; Flora Polonica (Woloszczak); Persia (Bornmiiller) ; 

 Indian grasses (C. B. Clarke); Borneo (Creagh); Tropical 

 Africa (Bates, Zenker, Scott Elliot) ; South Africa 

 (Schlechter, Medley Woods) ; Mexico (Pringle) ; Costa Rica 

 (Durand and Pittier). Schomburgk's Orchid drawings and 

 part of the collection of Salisbury's MS. and drawings, have 

 been arranged. 



Mr. Gepp has continued to study critically the mosses 

 collected in the British West Indies, and in connection with 

 this work has revised the Dicranacece, Bartramiaceoe, and 

 other orders. He has given much time to the separation, 

 revision, and preparation for publication of the West African 

 Mosses of the Welwitsch Herbarium. A further large portion, 

 amounting to 3,000 specimens, of the Hepatics of the Stephani 

 Herbarium, has been laid out and incorporated in the collec- 

 tion. And other additions amounting to 1,900 Mosses and 

 700 Lichens, and derived from various sources, such as the 

 Herbaria of Shuttleworth, Wilson and Bloxam, and collec- 

 tions from Australia, Tasmania, New Zealand and Tropical 

 Africa, have similarly been incorporated in the general 

 collection. 



Having received special leave of absence from the Trustees, 

 Messrs. Murray and Blackman accepted the invitation of a 

 sub-committee of the Government Grant Committee, to report 

 on the phyto-plankton of the Atlantic, especially the region 

 removed from coastal waters. They were absent on a voyage 

 to the West Indies for this purpose, from 16th June to 

 7th August. In addition to determining the results of this 

 voyage they have named large collections made by Capt. 

 Milner, Capt. Rudge, and Capt. Tindall. Not only has fresh 

 light been thrown on many obscure organisms by this work, 

 but a large collection of them (including many new forms) 

 has been obtained.
