318 MR ROBERT KIDSTON ON THE FOSSIL PLANTS OF THE 



I am doubtful if the plant figured by Lesquereux * as Annularia minuta (?), Brougt., 

 should be referred to Annularia galioides. On the other hand, the Annularia cuspidata, 

 Lesqx.,t does not appear to differ from Lindley and Hutton's species. 



On only one occasion has Annularia galioides been found in the Ayrshire Coal Field. 



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

 Horizon. — Above the Major Coal.

Remarks. — This species is not common. The specimens included here are similar to 

 Ettingshausen's figures given in Steinkf. v. Radnitz, pi. viii. figs. 1 and 4. Additional 

 notes will be found in my first " Report on the Yorkshire Carboniferous Flora" (loc. cit.). 



Locality. — Grange Colliery, Kilmarnock. 

 Horizon. — Shale over Stranger Coal.

Stachannularia tuherculata, Kidston (not Sternb. ; ref. in part), Catal. Palceoz. Plants, p. 55. 



Description. — Cone long, narrow, with numerous short internodes ; bracts numerous 

 (twenty to thirty in a whorl), short, thick, broadly lanceolate, striated, free above, 

 apparently united at the base, and forming a cup-like whorl ; axis thick ; joints very 

 short, ribbed. 



Remarks. — Four specimens of this cone have been communicated to me by the Rev. 

 D. Landsborough, all of which, however, belong to two individuals. The most perfect 

 one is shown at Plate IV. fig. 15. This shows nineteen whorls of bracts. The bracts are 

 broadly lanceolate, somewhat blunt-pointed, and their outer surface is distinctly striated
