340 MR ROBERT KIDSTON ON THE FOSSIL PLANTS OF THE 



Sagenaria dichotoma, Geinitz (in part), ibid., p. 34, pi. iii. fig. 2. 

 Phytolithus (cancellatus), Petreficata Derbiensia, pi. xiii. fig. 3, 1809. 

 (?) Lepidodendron simplex, Lesqx., Rept. Geol. Survey of Illin., vol. ii. p. 454, pi. xlv. fig. 5. 



Remarks. — Only one specimen of this species has come before me from the Kil- 

 marnock district. I originally regarded this species as a variety of Lepidodendron 

 rimosum, Sternb., to which it is certainly closely related. Feistmantel thinks it should 

 be united to Lepidodendron rimosum, though he treats it as a distinct species. I have, 

 however, seen so few specimens of Lepidodendron fusiforme and Lepidodendron rimosum, 

 that in the meantime, till there is an opportunity of comparing the two species, it is safer 

 to regard them as distinct. 



The plants differ in the leaf-cushions being contiguous in Lepidodendron fusiforme 

 and distant in Lepidodendron rimosum, but in certain other species both these characters 

 occur on the same plant, and unless some other character exists the closeness or distance 

 of the leaf-cushions is not sufficient for specific distinction. 



Locality. — Woodhill Old Pit, Kilmaurs. 

 Horizon. — Shale over roof of Durroch Coal. 



Lepidostrobus, Brongt. 

 Lepidostrobus variabilis, L. and H. 



Lepidostrobus variabilis, L. and H., Fossil Flora, vol. i. pis. x. xi. 



Remarks. — The cones of several species are probably included under this name. 

 Some specimens of Lepidostrobi from the Busbie Pits showed the macrospores very 

 distinctly. 



Locality. — Woodhill Quarry, Kilmaurs. 



Horizon. — Shale over Sandstone. 

 Locality. — Bonny ton Pit, Kilmarnock. 



Horizon. — Shale over Whistler Seam. 

 Locality. — No. 3 Pit, Springhill, Crosshouse. 



Horizon. — Shale over Major Coal. 

 Locality. — Busbie Pits, Kilmaurs. 



Horizon. — Two fathoms below Ell Coal.
