218 DTOZAMITES. 



type shown in woodcut 47 of the Geology of Yorkshire. It iff- 

 questionable whether the wiser plan would he to make use of one 

 of Zigno's specific names, hut as I feel practically no doubt as to 

 the specific identity of the specimens referred to 0. parallelus and 

 the type-specimen of Phillips' species, I have revived the name 

 instituted by this author. Some of the smaller forms of Zigno's 

 species Otozamites MoUnianus ' are, to some extent, intermediate in 

 form between 0. parallelus and 0. Feistmariteli. 



Otozamites parallelus may he compared also with a similar but 

 probably not identical species, Nilssonia pterophylloides, described 

 by Tokoyama from Japan.'' 



This type of frond is represented by a single specimen iu the 

 National Collection. The best examples are in the Leckenby 

 Collection, Cambridge (Nos. 218, 219), and in the Scarborough 

 Museum. 



51,410. A small specimen 10 cm. long and 2-6 cm. broad, 

 specifically identical with some larger examples ia the Leckenby 

 Collection, Cambridge. The pinnse are short and comparatively 

 broad, and the upper edge of the base is slightly eared. Labelled- 

 Oto%amites oltusus.
