Only for the sake of reference I may mention that quite recently 

 Nathorst (in Ofvers. af Kongl. Vetenskaps-Akademiens forhandlingar 1880 

 No. 9), tried to assign to Williamsonia a somewhat different syste- 

 matical position ; but as his view is based mostly on the same specimens 

 from which Phillips, Carruthers and Williamson treated it as cycadeaceous, 

 doubts may be entertained whether we should disbelieve these three 

 authors until many more typical specimens have been procured. In India 

 those forms, which I referred to Williamsonia occurred solely in association 

 with Cycadeacece. 



Squama? cycadearum, (? Gymnospermarum). 



Both in the Upper and Lower Gondwanas there occur certain scale-like 

 leaflets, which appear to belong to similar forms known from elsewhere, 

 and attributed to cycadeaceous or gymnospermous plants, as scales. Some 

 of those from the Upper Gondwanas could even be classed with a genus 

 from Europe, introduced by Count Saporta, while those of the Lower 

 Gondwanas must be left only with the above general denomination. 



Upper Gondwdnas : a. Umia group near Bhujuri in Kach • b. Sriper- 

 matur group at Vemaveram South Kistna district, and at Chirakunt, middle

 Aurunga coalfield. 



Lower Gondwdnas: a. Bardkar group in the Raniganj coalfield, b. 

 Baniganj group in the Rajmahal and Raniganj coalfields. 



Semina. 

 In the Rajmahal group (Upper Gondwanas) there occur small oblong 

 ovate, slightly compressed seeds, which agree in form and structure with 

 * Gigas - gigantic. t Proper name. % Of small appearance.
