146 DR ROBERT KIDSTON ON THE 



margin, lower margin rounded. Cicatricules three, placed about a third of length of leaf 

 scar from top — the two lateral elongate, diverging ; the central punctiform, and on level 

 with centre of lateral cicatricules. Ligule pit immediately above leaf scar, a short 

 distance above which is a straight transverse furrow. Surface of rib ornamented with 

 a leather-like shagreen and two slightly diverging rows of prominent transversely 

 elongated little elevations which descend from the base of the scars and terminate at 

 the transverse furrow. 



Remarks. — The position of the blunt lateral angles is below the centre of the leaf 

 scar ; and these being very obscure, give it a rounded appearance. 



The shagreen ornamentation of the cortex, of which the reticulations are relatively 

 large, and the two descending rows of elongated elevations, give a distinctive character 

 to this species. 



Sigillavia punctirugosa is very rare, and has only been met with at one locality by 

 Mr H. W. Hughes. 



Horizon and Locality. — Roof of Neiv Mine Coal: Mount Pleasant, Brierley Hill.

Remarks. — A small slab received from Mr Henry Insley contains some isolated 

 but characteristic bracts of this species. 



Horizon and Locality. — Blue Measures, six feet above Brooch Coal : Hamstead 

 Colliery, Great Barr, near Birmingham. 



Sigillariostrobus sp. 



Remarks. — Included here is a part of a cone which is closely allied to Sigillario- 

 strobus Goldenbergi Feistmantel,* but it is slightly smaller, and the bracts are ciliate.
