Dr. Gregory's account of his travels in East Tropical Africa 

 forms a handsome book — The Great Bift 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,

It may be well to call attention to the fact that the Cyperacece, 

 elaborated by Mr. C. B. Clarke, do not appear among the mono- 

 cotyledons, but form a "part" by themselves, coming after the 

 Fungi : the novelties, which appear as nomina nuda, were described 

 by Mr. Clarke in this Journal for May last, too late to be included 

 in the useful " list of literature " relating to his expedition which 

 Dr. Gregory gives in an appendix. An enumeration of the fresh- 

 water Alga^ 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 Elora 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
