OF SOME CARBONIFEROUS FERNS, .593 
that any trace of this is seen (fig. 13). The rachis of the primary 
and secondary pinne appears to be slightly winged. 
The pinnules towards the middle of the specimen in Pl. XXV. 
fig. 1, have 6-7 approximated segments; but on the lower pinne of the 
same figure, as well as in fig. 4, the segments of the pinnules are 
placed further apart and almost appear as bifid or trifid pinnules on a 
tertiary rachis. 
It will also be observed, that the pinnules are opposite in fig. 9, 
Pl. XXV., and alternate in most of the other specimens. 
Remarks, 
HyYMENOPHYLLITES DELICATULUS, Zeiller. 
The plant figured by Zeiller as Hymenophylltes delicatulus, in the 
Ann. d. Sciences Nat. vol.. xvi. pl. x. figs. 22-32, is referable to 
S, quadridactylites, Gutbier, which this author has regarded as a 
synonym of Zeilleria delicatula, Sternb., sp. Though the barren 
fronds of the two species have considerable resemblance, they are, 
however, essentially distinct. 
In Ayimenophyllites quadridactylites, Gutbier, sp., the pinnules are 
rounder and the lobes not so narrow. ‘The fructification also is of 
a different type. In HA. quadridactylites the sporangia appear in 
the fossils to have been situated beyond the apparent margin of the 
pinnule, and M. Zeiller informs me that he has observed what he 
believes to be traces of a column in the middle of some of the groups 
of sporangia of this fern, to which they were probably attached ; 
but owing to the indistinctness of this structure he refrained in his 
descriptions from affirming its presence, although he believes the 
appearance could not have been accidentally produced*. 
In the figure of Sphenopteris meifolia given by Ettingshausen in 
his ‘ Steinkohlenflora von Radnitz,’ the pinnules appear to be rounder 
than represented in Sternberg’s original figure; but the specimen 
from which Ettingshausen’s figure has been taken seems to have 
been indifferently preserved, so it cannot be critically considered. 
 Sphenopteris meifoha, Ludwig’, is not Sternberg’s plant, but is 
propably only a small form of the fern he has identified as Asplenites 
lindsceoides, Ett., from which, however, it also seems specifically 
distinct... 
The specific identification of the specimen figured by Gutbier as 
S. delicatulat, owing to the imperfect state of its preservation, is 
also subject to doubt. 
The specimens from which my figures are taken are in the 
collection of the British Museum, and my thanks are due to Dr. H. 
Woodward, F.R.8., for permission to figure and describe them.
