10 JOURNAL , BOMBAY NATURAL HISTORY SOCIETY , FoZ. Z/2. 
specimens we selected from my herbarium, in Calcutta, by Bengal 
artists, under the supervision of Dr. D. Prain, the Superintendent 
of the Royal Botanic Garden, Calcutta, who also kindly adopted 
the undertaking by his predecessor, Sir George King, to have the Plates 
lithographed for me (and the Bombay Natural History Society) in Cal- 
cutta, where, as is well known from the numerous examples in the 
ie Annals of the Royal Botanic Garden, Calcutta/’ such work is very effi- 
ciently done. My very best thanks are due to Dr. Prain for having 
thus so materially contributed to the preparation of this paper. 1 am 
also greatly indebted to him, as well as to Sir George King and Mr. J. 
F. Duthie, for their help in securing the co-operation of the Bombay 
Natural History Society for the publication of my paper in their 
valuable Journal. To Mr. Duthie I must also express my grateful 
thanks for having passed the final proofs for the press at Bombay, 
which has saved many weeks of time. Additional Plates will, I hope, 
be given from time to time, as I may be able to get them prepared ; 
the Society in Bombay is not wanting in liberality in that respect.
