of this paper may induce botanists to criticise my work, so that, 
should there be any value in it, it may ultimately be made more 
perfect in its character than it could n ow be without such help. 
The geographical range of the several forms is a most important 
and interesting ow sneered but I defer this also to a future 
occasion. I confine myse w to a notice of the geographical | 
range of each eset or rallide “of the representatiy e form in each 
group. The matter contained under the head ‘ <Oennenttng I 
suggests fetes as I believe will be found to be the case, forms 
be met with which it will be difficult ci place. As regar th the 
peonitent colour of the flowers in each group, I have as yet worked 
this out but imperfectly, and this study should especially be carried 
out in connection with insect-life. 
conclude my paper by inviting botanists kindly to communicate 
to me dried or fresh specimens of i interesting or new forms, and any 
remarks which may enlarge our knowledge of the genus, and 
thanking my numerous continental and other correspondents for 
their kind assistance, and more particularly for the loan of specimens 
of Paris; Mr. J. Lloyd; Mr. E. cass Mr. le Dr. B. Martin, of 
Aumessas; Mr. A. Kerner, of Vienna: Mr. W. Barbey, who has 
entrusted to me for examination the Enphrasias from the herbarium
