Remarks. — The Type-specimen of Sphen. dilatata, L. et H., 

 was recently identified among the ferns in the Natural History 

 Society's Collection. Though I had many years ago labelled it 

 as Sphen. dilatata, L. et H., yet the impression was so obscure, 

 and the shape of the stone so altered and unlike Hutton's figure, 

 that it was at that time passed without identification. Schiniper 

 has already correctly referred Hutton's figure, pi. 47, to Sphen. 

 irregularis, Sternb., and the latter and also Brongniart's Sphen. 

 oblusiloha are without doubt identical with Artis' Filicites tri- 

 foliolata. At present I do not think that Gutbier' s Sphen. num- 

 mular ia, judging from the figures given by that author, and the 

 figure given by Andrse, Yorw. Pflanz., pi. 11, and the specimen 

 referred to that species below can be united to this well marked 

 species. Like all widely distributed species it is variable in 

 appearance, but none of the specimens that I have seen from 

 this Coal-field have the pinnules so small as those of Sphen. 

 nummularia. The Sphenopteris latifolia and acutifolia, Brongt., 

 belong to Pecopteris muricata, and are very distinct from Hutton's 

 S. latifolia. Stur's S. foliolata, referred to above, is so near to 

 this that I do not see how it can be separated. 



Sphenopteris nummularia, Gutbier. 



Type — Sphenopteris nummularia, Gutb., Vers. Zwick. 



Schwarzk., 1. 10, 

 f. 7, 8; t.ll,f.3. 



Sphenopteris nummularia, Andrae, Yorw. Pflanz., taf. 11.

pi. 23, f. 2, 3, 4. 



114. — Sphenopteris nummularia, H. Cat., p. 109. 



The pinnules are very small, ovate, and with fine bifurcating 

 nervation. The pinna? are broken up into lobes on the basal 

 part, but are not divided at the extreme end. This specimen 

 has very small, lobed pinnules and the appearance of crowded 

 foliage. Very distinct in habit from any local fern. 

 Loc— Unknown. ? Whitehaven Coal-field. (H. C. 638). 



Remarks. — If the specimen No. 114 be correctly referred to 

 this species, then S. nummularia, as figured by Gutbier and
