[Read April 16, 1863.] 
| Wa have in preparation a monograph of the West African species 
of Amomum ; but as there are yet some points to be cleared up, 
requirimg further communieation with residents at Sierra Leone 
and the ports of Liberia and of the Gulf of Guinea, we shall not 
be in a position to complete it during the present session of the 
Linnean Society. It appears, however, to be desirable that brief 
diagnoses of the new species should at once be laid before the 
Society, and we have accordingly prepared the following. 
Specimens of all the plants described have been received, both 
in the dried state and preserved in fluid, accompanied in most cases 
by coloured sketches, from Mr. Gustav Mann, the able and per- 
severing botanical collector to the Royal Gardens, Kew. In the 
Museum and Herbarium of this establishment the authentic spe- 
cimens are deposited.
