 Vol. I., p. 405. 

 This species is founded on two small specimens from 

 Niedzielisko, near Jaworzne, having portion of their structure 

 preserved. 



The general arrangement of the sporangia ajDpears to be similar 

 to that which is found in S'pheno- 

 phyllum cunei/oliuni, Sternb. sp. 

 ( = S2)henophyUum Dawsoni, Will, 

 sp.). As in that species, the 

 sporangia were arranged certainly 

 in two, but probably in three, 

 concentric circles. There is, how- 

 ever, this important diiference in 

 Tig.1^.-SphenophyllumRomeri, Sphenophyllum Romeri, that the 

 Solms-Laubach. Diagramatic sporangiophores expand at their 

 sketch of the arrangement of distal extremity into a narrow 

 the sporangia. elongate peltate shield, from each 



of which are suspended two sporangia. (Fig. 24.)

Cone little modified in form from the ordinary foliage branch. 

 Basal portion of bracts united into a narrow sheath which 

 surrounds the axis, limb divided into two bifid forks. Sporangia 

 pyriform, united in groups of four, and sessile on the free 

 portion of the bract below the bifurcations. 



Fruiting specimens of this species have been collected by Mr. 

 Hemingway at WooUey Colliery, Darton, near Barnsley, from 

 the shale over the Barnsley Thick Coal (Middle Coal Measures, 

 No. 2172, &c.). 



The cones of S2)heno2)hyllum majus differ in some respects from 

 those of the other species whose structure is knowm. The inter-
