RADSTOCK SERIES OF THE SOMERSET AND BRISTOL COAL FIELD. 393 



The frond scars often touch laterally, but are occasionally separate. 



Caulopteris anglica differs from Caidopteris protopteroides, Grand' Eury,* in 

 the closed vascular circle surrounding, and not being within, the " horse shoe " 

 as in Grand' Eury's species, and further I have not observed any trace of the 

 small inner transverse vascular cicatrice, such as is described as occurring in 

 Caulopteris protoptei -oides. 



The specimen figured by Geinitz as Caulopteris peltigera is probably refer- 

 able to Caulopteris anglica.

Remarks. — Perhaps the fossils placed here may be stems of Caulopteris 

 anglica, deprived of their cortical envelope. They must not in any case be 

 regarded as a distinct species. 



Two of these stems are shown on Plate XXV. figs. 1, 2. The specimen 

 illustrated at fig. 1 shows an inner oval cicatrice on the frond scars. Fig. 2 

 represents the more common appearance of the fossil. 



Caulopteris Phillipsii, L. & H., does not appear to differ in any way from 

 Caulopteris macrodiscus, Brongt. 



Localities ; — Radstock ; Camerton (type of Caidopteris Phillipsii, L. & H.). 



Caulopteris, sp. 



Remarks. — I place here a few specimens which, on account of their 

 imperfect preservation, cannot be specifically identified, but may be distinct 

 from those already given.
