however, though not so clear, shows traces of the ventral leaves. 

 It must be remembered that the smaU ventral leaves are only 

 visible in one position. This species has a great resemblance 

 in its general aspect to some forms of Selaginella. 



Lycopoditbs ciliatus, Kidston, n.sp. 

 Fig. 2.-A. 

 This species is only known by one small specimen, of which 

 both fossil and counterpart have been preserved. 



The fossil shows one arm of a fork and part of another, the 

 larger being about l\ inches long. These two arms of the 

 dichotomy evidently represent the fructification of the species, 

 for mixed with the leaves are macrospores of small size. Ihe 

 fossil is flattened, and it is difficult to ascertain the arrangement 

 of the leaves or bracts, but they appear to have been in several 

 rows and were probably spirally placed. 



The sporangia seem to have been borne at the base of the 

 leaves on an ordinary branch which does not appear to have been 

 much modified or to form a distinct cone. The leaves are very 

 small, about I of an inch long, oval-lanceolate and distinctly 



ciliate. , , • • i. i-

This species has been fully described and figured m the 

 Annals and Mag. Nat. Hist, for 1884. It is very distinct from 

 the other members of the genus. 



The leaves appear to have been arranged in whorls, as shown 

 by their scars, on a portion of the stem from which they have 



been removed. 



The lar-er leaves are oval cordate, acuminate, with a strong 

 central midrib, and are rather more than a quarter of an inch long.
