Gregory's account of his travels in East Tropical Africa forms a handsome book — The Great Rift Valley — and contains much information and many notes upon the botany of the region traversed by him. The appendix includes a list of the plants collected by him, so far as at present determined — for the most part by the officers of the Botanical Department of the British Museum ; the novelties, as our readers will remember, have been described in this Journal. The arrangement of the list is somewhat odd, the authority for each name being dissociated from it and placed in a column by itself ; thus, " Species. Ethulia conyzoides Author.' L. Locality.

An enumeration of the fresh- water Algae collected during the expedition, by Messrs. W. and G. S. West, will appear in an early number of this Journal. Dr. Gregory comments on the absence of scientific literature on British East Africa, and points out our inferiority to Germany in this respect. *' The only work on Tropical Africa in English that can compare with these [German works] in scientific accuracy is The Flora of Tropical Africa, the last part of which was published in 1877 ; but this barely mentions British East Africa." It is little to our credit that nearly twenty years should have elapsed without any attempt being made to complete this Flora; but, notwithstanding
