Vemeuilinoides fischeri Tappan, new species 

 Plate 66, Figures 23-28 



Test large, free, flaring at the base, but comparatively 

 narrow and elongate, sides nearly parallel in the later 

 portion; chambers numerous, inflated, triserially ar- 

 ranged, increasing in proportional height as added; 

 sutures distinct, depressed; wall finely agglutinated, 

 surface smoothly finished; aperture loop shaped, at 

 the base of the inner face of the final chamber. 



Length of holotype 1.30 mm., breadth 0.39 mm. 

 Paratypes range from 0.36 to 1.77 mm. in length. 



Remarks: This species occurs in the Seabee and 

 Schrader Bluff formations of Turonian to Campanian 

 age, and their equivalent zones in the Ignek formation. 



VerneuUinoides fischeri, new species, differs from 

 Verneuilina parallela Cushman from the Craie Blanche 

 of France, in being longer, narrower and more tapering, 

 in having relatively higher chambers, and in lacking the 

 triangular section of true Verneuilina. V. bearpawensis 

 (Wickenden) has more inflated and higher chambers 

 and a more twisted test. 



The species is named in honor of W. A. Fischer, 

 geologist, U. S. Geological Svu-vey, who coUected some 

 of the material containing this species. 



Types and occurrence: Holotype (USNM P4356), 

 figured paratypes (USNM P4357a,b), and unfigured 

 paratypes (USNM P4358) from the Upper Cretaceous 

 part of the Ignek formation (field sample 46 A L 66), 

 at the base of the section exposed at the forks of the 

 Ivishak and Sagavanirktok Rivers, at approximately 

 lat. 69°30' N., long. 148°30' W., northeastern Alaska. 

 Collected by E. H. Lathram, 1946. 



Figured paratype (USNM P4359) from a core at 

 571-574 feet, unfigured paratype (USNM P4360) from 

 a core at 500-510 feet, unfigured paratypes (USNM 

 4361) from a core at 589-602 feet, unfigured paratypes
