Sauveur (pl. xx., figs. 1—2, not fig. 3), as the pinnæ, and 
frequently the pinnules, end in spine-like points, from 
which character I originally referred the species to Sphen- 
opteris spinosa Gopp. 
Owing to the indistinctness of his figure and the ab- 
sence of description and details of the pinnule cutting and 
nervation, I cannot determine whether or not Stur’s Arche- 
opteris sauveuri (Stur, Carbon Flora, Schatz. Schicht. Die 
Farne, pl. xxxv., fig. 2, 1885, without description) should be 
placed here. But as his plant is evidently not an Arche- 
opteris, but a Sphenopteris, and as there is already a 
Sphenopteris sauveuri Crépin (Bull. Soc. Roy. de Belgique, 
vol. xix., part ii., p. 17) a new specific name is necessary 
in any case.

Hor.— Barnsley Thick Coal. 1oc.—Acton Hall Colliery,

Nork.—Fruiting specimens of this fern, received from 
Mr. Hemingway, shew that this species must be placed in 
the genus Renaultia. It may be further noted that, ac- 
cording to Zeiller’s figures of Sphen. ( Renaultia) gracilis 
Brongt. (Flore foss. d. bassin houil. d. Valen., p. 94, pl. iv., 
figs. 2—3), Renaultia footnert must be united with that 
fern. Brongniart’s type of Sph. gracilis (Hist. d. vćgćt. 
foss., p. 197, pl. liv., fig. 2) came from near Newcastle-on- 
Tyne, and I incline to the union of the two species, but 
the subject requires to be further looked into.
