XLVIl] CALLITRITES 339 



Cenomanian of Moravia where it is represented by both sterile and 

 fertile shoots; the cones are quadrivalvate. It occurs in the Middle 

 Cretaceous of Staten Island though without any cones : Ho Hick and 

 Jeffrey 1 regard the shoots referred by them to Widdringlonia 

 Reichii as Araucarian on the ground that the bordered pits on the 

 tracheal walls are usually contiguous. There is, however, no sub- 

 stantial reason for assigning these vegetative organs to the Arau- 

 carineae though the structure of the wood shows an Araucarian 

 tendency. Berry 2 records the species from the Cenomanian Raritan 

 formation of New Jersey and he expresses the opinion that the 

 species is closely allied to some Potomac specimens described by 

 Fontaine 3 as Taxodium ramosum, but in the absence of cones a 

 definite determination of affinity is hardly possible. 



Callilriles subtilis (Heer). 



Founded by Heer 4 on slender twigs bearing spirally disposed, 

 appressed, leaves from the Cretaceous beds of Atanekerdluk in 

 Greenland and described by Newberry 5 from the Amboy clays. 

 Hollick 6 and Berry 7 have also recorded the species from Cretaceous 

 strata in different parts of the Eastern United States and the latter 

 author figures examples from Upper Cretaceous beds in South 

 Carolina 8 . The epidermal cells are regularly rectangular and the 

 stomata are surrounded by 5 6 accessory cells. Berry figures 

 conical cones, 7 9 mm. long by 4 5 mm. in diameter, composed of 

 four thick scales differing somewhat in shape from the cones of 

 recent species. The sterile shoots of this species bear a close resem- 

 blance to C. Reichii and the two species have often been confused ; 

 also to Cyparissidium minimum as figured by Velenovsky 9 , 

 Juniperus madlenta Heer 10 and Widdringtonites fascicularis Holl. 11
