218 OTOZAMITES. 



type shown in woodcut 47 of the Geology of Yorkshire. It is 

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

 of Zigno's specific names, but 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 Molinianus ' are, to some extent, intermediate in 

 form between 0. parallelus and 0. Feistmanteli. 



Otozamites parallelus may be compared also with a similar but 

 probably not identical species, Nilssonia pterophyttoides, described 

 by Yokoyama from Japan. 2 



This type of frond is represented by a single specimen in 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 10cm. long and 2-6 cm. broad, 

 specifically identical with some larger examples in the Leckenby 

 Collection, Cambridge. The pinnae are short and comparatively 

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

 Otozamites obtusus.
