OBSERVATIONS ON HOLL’S LIST. 25 
to Tuckey's Voy.), which Mr. Höll himself does not distin- 
guish from A. Capillus, Linn. 
** Aspidium auriculatum, Sw.," ought, no doubt, to be A 
falcinellum, Sw. See Primitie, Faune. et Flore Mad. in 
Camb. Phil. Soc. Tr. p. 5, n. 1.* 
** Aspid. Filix mas, Sw.,” is probably A. affine, nob. MSS. 
a very nearly allied species indeed, whose characters I shall 
shortly publish in the Camb. Tr. Of what I consider the 
genuine A, Fiir mas, Sw., I have never found specimens in 
Madera. 
* A. spinulosum, Sw.,” is probably A. elongatum, Sw. 
“A. dilatatum, Sw.," is no doubt myA . fænisecii. 
** A. lobatum, Sw.,” is perhaps rather A. angulare, Sm. not 
Willd., according to Mr. Arnott, who also considers Smith's 
plant identical with A. orbiculatum, Desv., and with A. loba- 
tum of Willd. and of Hooker, but not of Swartz. 
* A. regium, Sw.," I have never found; but A. fragile, Sw. 
is extremely common, and, no doubt, the plant here intended. 
In identifying most of the above Ferns, I have been guided 
as well by the affinities of the species as by considerations of 
a general nature; and the four last are so common, that it is 
impossible to suppose that they are not contained in Mr. Hill's 
List, though under different names from mine, It has, how- 
ever, two species, Aspid. patens, Sw., and Aspid. Oreopteris, 
Sw., for which I cannot, on any principles, account: and I, 
on the other hand, possess two, which cannot be identified 
either with these or with any others of his List. So that it wil] 
be betterto subjoina copy, in parallel columns, of ourrespective 
lists of Aspidium, and afford to others, one, at least, of the modes 
* “Primitiæ Faune et Flore Madera et Portus Sancti; sive species 
quaedam nove vel hactenus minus rite cognitze Animalium et Plantarum 
in his Insulis degentium breviter descriptz, curante Ricardo Thoma Lowe,

A truly classical production, which does my valued friend no less credit 
as a most observing and accurate Naturalist than a scholar and “ travel- 
ling bachelor” of a great University.
