186 Berry — A Pseudocycas from British Columbia. 



and therefore not older than Turonian, although it should 

 be stated that many geologists are of the opinion that the 

 Atane beds of Greenland are not as old as the Ceno- 

 manian, so that Pseudocycas unjiga may really have been 

 contemporaneous \vith the Greenland species. 



The specimen from Moberly Lake corresponds with 

 Dawson's figure 2a and I have nothing like his figure 2. 

 My material and Dawson's figure 2a are distinguishable 

 \\T.th difficulty, if at all, from such specimens of Pseudo- 

 cycas insignis as Nathorst's plate 1, figure 2 and, on the 

 other hand, Dawson's figure 2, in so far as I can tell from 

 the rather poor figure, is like the Pseudocycas pumilio of 

 Nathorst. It may be that Pseudocycas unjiga repre- 

 sents these two Greenland forms and should be reduced to 

 synonymy. With the continued exploration of the country 

 adjacent to the Peace and Pine rivers, material that will 

 permit of microscopical study is almost sure to come to 

 light, at which time the question can be finally settled.
