Botanical Journey to West African Coast. 473 



As most of the period of four months, which elapsed 

 from the time of my departure from Liverpool to that of 

 my return to London, was spent at sea, but few oppor- 

 tunities presented themselves for making extensive collec- 

 tions of land plants at any place, and, moreover, such 

 chances as did occur were somewhat encroached upon by 

 the simultaneous attempt to form collections of such shore 

 animals as could be obtained. The reports upon tliese 

 latter, as well as upon the many other marine gatherings 

 of surface forms, must be relegated to another place ; but 

 it is intended to present a detailed account of the marine, 

 shore, and fresh-water Diatomacece collected during the 

 expedition to this Society at a later period, as w^ell as 

 to la}^ before it statistics of the marine and fresh-water 

 Algae which were procured, and which are at present 

 excluded. 



Gatherings of jjlants were made at the following places 

 on the dates undernoted : — 



1. Madeira (vicinity of Funchal), December 10, 1885. 



2. Teneriflfe (vicinity of Santa Cruz), December 12, 1885, and

The collections made at Madeira and TenerifFe in 

 December 1885 were unfortunately destroyed by the 

 exposure to the very warm and humid climate of the 

 Tropics, as they were made during the outward voyage, 

 previous to joining the "Buccaneer" at Sierra Leone on 

 December 22, and before it was possible to have the ade- 

 quate means of preserving the specimens. The second 

 gathering made at Santa Cruz on the homeward voyage was, 

 however, preserved ; but as no call was made at Madeira
