 pi. iv, figs. 9, 10. 

 Ottokaria bengalensis, Zeiller, ibid., prefatory note. 



Type. Nos. 7287-8, Mus. Geol. Surv. India, Calcutta. 



Leaf orbicular, with a long petiole, measuring 30 mm. in 

 diameter, margin sub-acutely dentate, nerves consisting of fine 

 strands united into bundles, radiating from the base of the leaf 

 and dividing dichotomously. 



Zeiller ! has pointed out that the details of the nervation of the 

 Indian leaf may be closely compared with those of the genus 

 Wliittleseya, especially W. elegans, Newberry, from the Carboniferous 

 of the United States, although the form of the leaf is altogether 

 different. In the latter respect he has compared this new species 

 Avith certain Mesozoic members of the genera Baiera and Ginkgo, 

 and with lihijn'dopsis ginkgo ides, Schmal. He concludes that the 

 Indian fossil may be referred provisionally to the Ginkgoales. 



Ottokaria bengalensis is known only from a single specimen, 

 derived from the Ivarharbari Beds at Passerabhia, India. 



Not represented in the British Museum collection.

 much-branched stems. Leaves numerous, simple, entire, com-

 tetragonal, decurreut at the base, falciform, keeled, acuminate. 

 The larger leaves, especially towards the ends of the branches, 

 long, linear, more or less distichous. Cones cylindrical, very 

 elongate, composed of scales loosely imbricate, coriaceous, lobed 

 distally into 3-5 rounded lobes, each usually subtending 2-3
