186 NOEGGERATHIOPSIS. 



V. 8323. Described by Seward (92 2 ), p. 93. 



A piece of white sandstone, with a basal portion of a long leaf, 

 20 cm. in length, and nearly 5 cm. across. The nervation is not 

 very clear, but the nerves do not appear to anastomose, and are 

 nearly parallel. The leaf is markedly constricted towards the base. 

 Fragments of fronds of Glossopteris are also associated.

Type. ~No. 5036, Mus. Geol. Surv. India, Calcutta. 



Leaves ovate - spathulate, rounded at the apex, gradually 

 contracted at the base, unsymmetrical. Nerves strong, radiating 

 from the base at a very acute angle, with frequent dichotomy, 

 those of the median portion of the leaf sub-parallel, those in the 

 lateral portions arched towards the margin. 



The figures given by Feistmantel of these leaves from the 

 Karharbari Group in India recall some of the broader forms of 

 Noeggerathiopsis Rislopi (cf. with Feistmantel (79 1 ), pi. xx, fig. 2) 

 in shape and general nervation. They apparently differ only in 

 the larger size, broader outline, and in the nervation being less 

 nearly parallel, more arched, and more subdivided. These differ- 

 ences in the nervation, however, may be very well accounted for 

 by the larger size of the leaf. Feistmantel placed them in a 

 new genus Euryphyllum on the grounds that they were borne 

 spirally on a broad axis, which he figures. He, however, admits 

 (explanation to his figure (79 1 ), pi. xxi, fig. 1) that there is no 

 real evidence of continuity between the leaves and the axis. It 

 seems to me safer for the present to conclude that these leaves 

 belong to the genus Noeggerathiopsis, and to compare them with 

 N. Ilislopi, which they so closely resemble in habit.
