veins pursuing a vertical course and gradually passing obliquely 

 upwards and outwards towards the upper end of tbe lamina. 

 While bearing a resemblance to Gangamopteris Jcashmirensis, Sew./ 

 the specimen is, we believe, identical with Feistmantel's species 

 from the Talchir and Karhabari Beds of India.^ 



Callipteridium sp. (PL IX, fig. 3; & text-fig. 7.) 



The faintly-marked impression (10 centimetres by 2*5 cm. in 

 breadth) represented in PI. IX, fig. 3 consists of an axis bearing alter- 

 nately-placed obtuse and slightly-falcate pinnules attached by the 

 whole of the base. Each pinnule has a well-marked midrib (text- 

 fig. 7) ; the secondary veins are almost completely obliterated, with 

 the exception of a very few indistinct traces here and there, which 

 show that they were curved and forked. The more perfect pinnules 

 have a length of 1-3 centimetres and a breadth of 5' millimetres.

Africa with which to

 the species originally 

 described by Royle as 

 Pecopteris Lindlegana, 

 and afterwards from the 

 Damuda Beds of India by 

 Feistmautel as Aletho- 

 pteris Lindleyana. We 

 cannot hope to determine 

 the very indistinct speci- 

 men with any degree of 

 certainty, but we do not 

 consider its resemblance to the Indian species sufficiently close to 

 justify the use of the same name. The species Callipteridium gigas 

 (Gutbier), figured by Renault & Zeiller,^ from Commentry, bears 

 a close resemblance to the Yereenigiug specimen ; we must wait, 

 however, for more evidence before suggesting specific identity with 

 any known type.

Specimens of this species were described at length in a paper 

 read before the Society in 1897. Larger examples of the same 

 form have since been found in the Yereeniging quarry; one of the 

 largest that we have seen measures 30 by 50 centimetres.
