APPENDIX. 251 



Remarks. As far as can be learned from the description and figure of 

 Lesquereux's Sphenopteris Harveyi it seems to be identical with the fruiting 

 specimens of Zeilleria {Sphenopteris} delicatula, Sternberg, which were 

 described by me in 1884 (Quart. Journ. Geol. Soc. 1884, p. 590, pi. xxv.). 

 The specimen figured by Lesquereux does not appear to be so well preserved 

 as those in the Collection, but the characters it shows agree perfectly with 

 the British examples. Lesquereux's description of Sphenopteris Harveyi and 

 my paper on Zeilleria delicatula, Sternb., sp., were both in course of publi- 

 cation at the same time, so neither had the opportunity of availing himself 

 of the other's investigations. Since seeing my paper Lesquereux has informed 

 me that he is also of opinion that his Sphenopteris Harveyi is similar to 

 Zeilleria delicatula. 



CALYMMOTHECA, Stnr, emend, (ante, p. 66).

Sphenopteris (Diploihmema) Tracyana. 



Lesquereux, Coal Flora in Pennsyl. vol. iii. p. 766, pi. ci. fig. 2, 1884. 



Remarks. Sphenopteris Tracyana seems to be synonymous with Calym- 

 motheca (Sphenopteris) ^ bifida, L. and H. Lindley and Hutton's type of 

 the species is certainly not well preserved, and is misleading as to the real 

 characters of this fern. The most characteristic figure of Calymmotheca 

 bifida, L. and H., sp., with which I am acquainted is the woodcut given by 

 Hugh Miller (Testimony of the Eocks, 1st ed., p. 466, fig. 129). This will at 

 once show the identity of Lesquereux's species with Lindley and Hutton's 

 plant.
