 interested in the subject of island-floras are equally due, for having 

 so kindly afforded his officers these opportunities of landing 

 on, and investigating the botany of, the islands of this group. 



In the list itself purely cultivated species are indicated by a 

 distinctive type ; species that have become ' escapes,* even though 

 they may at the same time be ' cultivated, ' and trees that, though 

 they may be ' planted,' occur also as * indigenous ' species, are not 

 distinguished in this way. The references in the list are mainly 

 to Dr. Roxburgh's Flora Indica and to Sir J. D. Hooker's Flora, 

 of British India, and as regards cultivated and economic species 

 also to Dr. Watt's Dictionary of the Economic Products of India,

The Scorpions discussed in the present paper are referable to two 

 families — the Bnthidce and the Scorpionidai. 



Of the Butliidfp, a family which is characterised by a small trian- 

 gular sternum, only two genera are known to occur in India — namely 

 Buthiis and Isomotrua. The former, containing but one species that is 

 recorded below, may be recognised from the latter by having the 

 cephalothorax distinctly keeled, two teeth on the lower edge of the 



by those outside it who, like the writer, had the privilege of enjoying his personal 

 friendship, but by every zoologist and botanist in the East, because of the 

 interest he took in, and the great practical sympathy he always showed fof, every 

 branch of biological research.
