have here, in close association, cycad trunks of rather slender habit with Ptilophyl- 

 lum leaves and Williamsonia fruits. The next reference to Indian cycad trunks, 

 so far as I know, is by Seward, who figures preliminarily a cycad trunk from India 

 with its principal structural details indicated. This specimen has Ptilophyllum 

 cutchense leaves attached (149). 



Before leaving the subject of Indian cycads it nun- be well worth while to 

 mention several occurrences of associated leaves and fruits. The genus Ptilophyllum 

 is more common than any other in the flora of Kach and of the Rajmahal Hills, 

 and in both is found accompanying typical Williamsonia fruits, as shown in the

subjoined text-figure 2. In his Jurassic Flora of Kach (47), Feismantel figures 

 three different slabs, each bearing the fruit Williamsonia Blanfordi, accompanied by 

 characteristic portions of Ptilophyllum cutchense fronds ; though, for reasons not 

 clear, no mention is made of the latter fact in the description (47, p. 42), reference 

 being made solely to the fruits. Similarly, in various European localities there 

 is the corresponding association without actual organic connection of the fronds 

 called Cycadites pec/en, or Williamsonia pecten and peclinoides, with the small 

 fruits named Williamsonia Leckenbyi. Moreover, no one has yet pointed out a 

 single indubitable generic difference between the Indian and European forms just 

 mentioned, so that their nomenclature is a moot point despite their consequent 

 great interest and importance from every point of view. Evidently in such a case
