222 OTOZAMITES. 



0. Massalongianus J is specifically identical with 0, Feist mantel i, 

 but the latter name has been adopted on account of the more 

 striking agreement of the specimens so named by Zigno with the 

 English examples. 



Some of the smaller fronds of Otozamites Molinianus 2 may be 

 compared also with 0. FeistmanteU, as well as with 0. parallelus. 

 One or two of the specimens from Italy figured as Otommites 

 veronensis, Zigno, 3 are also very similar to 0. FeistmanteU. 



The Indian Cycadean leaves named by Oldham & Morris 

 Palceozamia lengalensis 4 are practically indistinguishable from 

 0. FeistmanteU. 



The frond described by Kurr from a German locality as Zamites 

 MandelsloM 5 is closely allied to, if not identical with, Otozamites 

 FeistmanteU. Another example of a similar type of leaf is afforded 

 by 0. Reglei as figured by Saporta. 6 These two species are com- 

 pared by Lignier with a similar type of Otozamites (0. crassifolius'), 

 which he has described from a Lias locality in Normandy. 7 



The York specimen of Otozamites FeistmanteU has a length 

 of 22cm.; the pinnae vary in length from 8mm. to 1-4 cm., 

 having an average breadth of 6 mm. The example in the Leeds 

 Museum represents a smaller frond, bearing pinna3 about 8 mm. long. 



V. 3683. This is the only specimen in the British Museum 

 which appears to be identical with Zigno's species ; it is 6 cm. long 

 and 1 cm. in breadth, bearing short, broad, and closely set pinnae.
