paration of this Revision. With one or two ex- 
ceptions, the order followed and the names given 
are those of Syn. Fil., 2nd Edit. The Cape loca- 
lities are simply adopted from Lady Barkly. Some 
of the points ascertained from the Rawson Herba- 
rium are specially mentioned ; others are silently 
embodied. Since my return from Umpumulo, an 
examination of Dr. Kuhn’s Filices Africance — (a 
marvel of critical analysis and laborious diligence,) 
— has raised several questions, for the settlement 
of which I might have found means in that mag- 
nificent Natural Fernery, but which must now lie 
over. Some of these are indicated in the list, and 
brother-collectors are invited to aid in seeking 
their solution. Several Transvaal species are 
noted, and amateurs would do well to keep a look- 
out for them in our own northern districts ; but, 
doubtless there are many more yet undiscovered 
in that great country, perhaps in our own. In a 
small collection, lately sent to Durban from the 
Gold Fields by Mr. T. Ayres, at least six species 
appear which I have never seen in Natal, and 
some of them never at all. Unfortunately nearly 
the whole of the Trans-Mooi and Trans-Umlazi 
portions of Natal are unknown to me ; and, con- 
sequently they are practically ignored in this com- 
pilation, for I have limited myself to what I know 
cither from personal explorations or otherwise. 
But what is here given may prove a help to 
amateurs, and perhaps encourage some brother- 
invalids, medically exiled like myself from stern 
official life, to try the remedial powers of frequent 
rambles, portfolio in hand, over the bracing heights 
and in the cool shady ravines of our charming 
uplands. Finally, let it be understood that, as the 
findings of brother-collectors are embodied here 
along with my own, the first person plural of this 
Revised List is employed legitimately, and not as 
a mere editorial conventionalism.
