KILMARNOCK, GALSTON, AND KILWINNING COAL FIELDS, AYRSHIRE. 343 



Zeillee, in the same work (loc. cit.), treats Lepidostrohus ornatus as a distinct species. 

 My own opinion is, that Lepidostrohus omatus, L. and H. (I do not say ornatus of 

 other authors), cannot be separated by any definite characters from their Lepidostrohus 

 variabilis. The specific point upon which Zeiller lays great importance in the 

 distinction of these two species — the swelling on the " knee " of the bract on which the 

 sporangia sits — is not shown on any of Lindley and Hutton's figures of Lepidostrohus 

 ornatus; and further, the Lepidostrohus ornatus, var. didyma, L. and H. (vol. iii. 

 pi. clxiii.), does not belong to the species figured in their vol. i. pi. xxvi. I arrive at 

 this conclusion from the fact that the cone occurring at Newhaven* (var. didyma) 

 I have found attached to a species of Lycopod that does not occur in the Coal 

 Measures at all, from which horizon the types of Lepidostrohus ornatus originate. 



The chief character by which I separate my Lepidostrohus squarrosus from Lepido- 

 strohus variabilis is its larger size, and the much more lax spreading nature of the bracts. 

 The individual bracts are not very clearly seen, but they seem to be identical with the 

 figure given by Zeiller. Their free portion is lanceolate, acute, and single veined. 



The specimen shown on Plate IV. fig. 13, which occurs on the slab alongside of 

 another example, was communicated to me by the Kev. D. Landsborough.

Remarks. — This species is frequent, but the specimens are usually fragmentary. Mr 

 Lomax showed me a specimen of Lepidodendron fuliginosum, Will., with the bark 

 attached, from which it was seen that Williamson's plant is a Lepidophloios.
