short papers by the latter author have thus far been published. 1 A few of 

 the species collected by White and Schuchert have been identified by 

 Knowlton (op. cit.) ; and Beust/ Vanhoffen and Englehardt/' and 

 Menzel 4 have published short papers relating to this area. 



The Upper Cretaceous beds form part of a sedimentary series with a 

 thickness of about 4000 feet, derived from the eastward and embracing 

 Lower (Kome), Middle (Atane) and Upper (Patoot) Cretaceous, as well 

 as the so-called Arctic Miocene, which according to Menzel (op. cit.) is 

 partly Aquitanian. The clastic beds are exposed at numerous points 

 along the deeply indented coast in a belt about 75 miles wide, extending 

 from latitude 69° 15' to 72° 15' north. They rest on a very irregular 

 floor of gneiss, granite, diorite and basalt and dip slightly to the westward, 

 although they are faulted locally and show variations in thickness. They 

 are overlain by from 3000 feet to 4500 feet of horizontally bedded 

 Tertiary basalt. 



Heer considered all of the north shore of the Xugsuak peninsula from 

 Kome westward to Ekorgfat as belonging to the Kome series, although in 

 places the sediments are as much as 1500 feet in thickness. Xordens- 

 kiold considered the beds above 750 feet above tide as representing the 

 Atane beds, since he found fragments of Sequoia fastigiata, an Atane 

 species, at this level, although there appears to be no lithologic break. 



The work of White and Schuchert (op. cit.) as well as that of Vanhoffen 

 and Engelhardt (op. cit.) confirm Nordenskiold's results and show that
