214 OTOZAMITES. 



A specimen in the Scarborough Museum, which is no doubt 

 identical with this species, has been named by Richards 1 

 Otozamites Phillipsii, but no description of the species has been 

 published. Good examples are contained in the collections at 

 Whitby and Cambridge. Specimens of Otozamites graphicm are 

 occasionally met with labelled 0. acuminatus, but the falcate form 

 of the pinna? and their more regular oblique attachment to the 

 rachis afford distinguishing features. 



40,515. PL I. Fig. 2. 



A portion of a frond 1 1 cm. in length. The figure shows the 

 upwardly directed and pointed tips, the strongly falcate form, and 

 the well-marked lobes and spreading veins which characterize the 

 pinnae of this species.

This smaller example is in all probability specifically identical 

 with the larger frond (40,515) ; the comparatively short, more 

 falcate, and pointed pinna3 constitute a difference between this- 

 specimen and the frond of similar size referred to Otozamites 

 oltusus, var. ootiticus, as represented in PL II. Fig. 2.
