SECTION AT THE rr.HN LBDOBS. 517 



richly with beautifully preserved remain* of plants, among which are 



the following species : — 



Catamites transitionis, Goeppert. Occasional, in large, erect 

 specimens. — Aster ophyllites lattfolia, Daws. Extremely abun- 

 dant, often showing ten or twelve whorls of leaves, sometime* 

 with many branches. — A. acicularis, Daws. Also very abun- 

 dant. — (?) A. longifolia, Brongn. — A. scutigcra, Daws. The 

 curious stems of this species, with their scale-armed nodes, 

 occur abundantly in this bed. — SphenophyUum antiquum, 

 Daws. — Pecopteris obscura, Lcsqx. — Sphenopterie Bp. ? — 

 Cardiocarpum cornutum, Daws. Rare. — Pailophyton rlcyans, 

 Daws. Occasional. I have never detected any trace of 

 Cordaites liobbii, Daws., in this bed. It is extremely common 

 in the overlying strata. 

 Gray sandstones and flags, with occasional ill-preserved plants, Cata- 

 mites transit io)iis, Goeppt., Cordaites Mobbii, Daws. — Aster ophyllites 

 and Stcrnbergiaj ..... 2 feet 6 inches. 

 Black arenaceous shales of the same character as those 



of No. 1, but without fossils, so far as I have examined 1 1 inches. 

 Compact flaggy, gray sandstone, with badly preserved 



plant remains, Catamites, etc. .... 2 feet. 



Very soft, dark, lead-coloured shales, much slicken-sided 

 and charged with fragments of plants. This bed is 

 so soft that the action of the weather and the sea have 

 everywhere denuded it to the level of the beach . . 4 feet. 



Plant-bed No. 2 ...... 1 foot. 



At the point where the section crosses the bed, and where I first 

 discovered it, it consists of very compact and hard, light lead-coloured, 

 slate-like, arenaceous shale ; but the character of the shale varies 

 much in its different exposures, being sometimes very soft and fissile, 

 and of a very black colour. The following is the list of species which 

 it affords : — 



Catamites transitionis, Goeppt. Occasionally ; never in good 

 specimens. — C. canna'formis, Brongn. Occasionally ; never 

 in good specimens. — Aster ophyllites aciculari<. Daws. Rather 

 rare. — A. latifolia, Daws. Bather rare. — A. tongifolia, Brongn. 

 Rather rare. — A. parvula, Daws. Whorls of a minute 

 Aster ophyllites, which may belong to this species, arc not 

 infrequent in this bed. — Annularia acuminata, Daws. — 

 Pinnularia dispalans, Daws. Abundant. — Psilophyton elegans, 

 Daws. Quite common, always in fragments, never in good 

 specimens. — P. glabrum, Daws. Flattened stems, with a wavy
