the number of actual species : it is obviously impossible to decide 

 with any assurance how much value should be attached to differ- 

 ences in size or to slight variations in form, but the main point is 

 that cones and cone-scales of the Araucarian type are among the 

 most familiar Jurassic fossils. The following selected examples 

 are chosen in illustration of this statement and reference to others 

 will be found in some of the sources quoted in the footnotes. 



Araucarites Phillipsi Carruthers. 



Carruthers 1 described this species from the Middle Jurassic 

 rocks on the Yorkshire coast : the type-specimen is in the Leckenby 

 collection in the Sedgwick Museum, Cambridge. The scales are

cuneate, nearly as long as broad (fig. 740, 9), and in shape similar 

 to those of the cone already described as Araucarites ooliticus 

 (Carr.). 



Examples of French Jurassic cone-scales are afforded by 

 Araucarites Moreauana Sap. 2 , from Corallian beds near St Mihiel
