214 OTOZAMriES. 



A specimen in the Scarborougli Museum, whicli is no doubt 

 identical with this species, has been named by Eichards * 

 Oiozamites PhiUipsii, but no description of the species has been 

 published. Good examples are contained in the collections at 

 "WTiitby and Cambridge. Specimens of Otozamites graphicus are 

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

 of the pinnae and their more regular oblique attachment to the 

 rachis afford distinguishing features. 



40,515. PI. I. Fig. 2. 



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

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

 the well-marked lobes and spreading veins which characterize the 

 pinnae of this species.

40,690. PL II. Fig. 6. 



This smaller example is in all probability specifically identical, 

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

 falcate, and pointed pinnae constitute a difference between this- 

 specimen and the frond of similar size refen-ed to Otozamites 

 ohtusus, var. ooliticus, as represented in PL II. Fig. 2.
