probably a mixing of levels and possibly also of Museum labels. 

 Thirteen of the Greenland forms are considered to be identical 

 with Pierre and Fox Hills species, and only three — an Action 

 and two Foraminifera, are common to the Atlantic Coastal Plain 

 Cretaceous. Either this resemblance to our Western Interior 

 Cretaceous and lack of similarity to the Coastal Plain Cretaceous 

 is more apparent than real, or else some links in the chain of dis- 

 tribution should eventually turn up somewhere in the Arctic Ar- 

 chipelago. It may well be that a seaway extended westward 

 from Disko Island instead of there having been any connection 

 with the Atlantic, as has usually been supposed. The large num- 

 ber of West Greenland land plants found in our Coastal Plain 

 Cretaceous may be considered as pointing in the same direction. 

 The present paper does not, unfortunately, settle the vexed 

 question of age. Heer described four large fossil floras from that 

 region: the Kome, Atane, Patoot and Atanekerdluk which he 

 correlated respectively with the Urgonian, Cenomanian, Senonian, 

 and old Miocene. The reviewer has regarded these floras as Bar- 

 remian-Aptian, Turonian, Senonian, and upper Eocene or lower 

 Oligocene respectively. All of these floras suffer from the un- 

 certainties of mixed collections and over elaboration. There 

 seems to be a relatively large number of species through the 

 whole Cretaceous part of the section, which it seems emphasizes 

 the failure to solve the local stratigraphy, although the presence 

 of at least four difi:erent floras stands out clearly through this 

 mist of uncertainty. Occurring as these plants do near the 

 theoretical center of radiation of the flowering plants, this ques- 

 tion of their true age is of the greatest importance. It is clearly 

 worth the trouble and expense of field work in the region and its 

 elucidation might well have added some luster to the almost total 

 lack of scientific results of Peary's many expeditions.
