Genus Siphotextularia Finlay, 1939 



Siphotextularia? rayi Tappan, new species 

 Plate 66, Figures 6, 7 



Test free, biserial, somewhat flaring; chambers 

 inflated, relatively high, and increasing rapidly in 

 size; suWes distinct, depressed, horizontal; wall finely 

 agglutinated, smoothly finished, white; apertm-e a slit 

 in the terminal face of the final chamber, not extending 

 to the base of the chamber. 



Length of holotype 0.55 mm., breadth 0.31 mm., 

 thickness 0.08 mm. Paratypes range from 0.44 to 

 0.60 mm . in length. 



Remarks: Siphotextularia? rayi, new species, differs 

 from S. washitensis Loeblich and Tappan in being 

 larger, with higher and more infiated chambers and more 

 nearly horizontal sutures. It is not a typical Sipho- 

 textularia in that it is not quadrangular in section, 

 but seems closest to that genus in the terminal apertural 

 character, although the aperture is not produced on a 

 neck. It occurs in the Grandstand and Topagoruk 

 formations. 



The specific name is in honor of E.. G. Ray, geologist, 

 U. S. Geological Survey. 



Types and occurrence: Holot5rpe (USNM P4304) 

 and unfigiu-ed paratypes (USNM P4305) from a core 

 at 660-670 feet in the Topagoruk formation, in South 

 Barrow test well 2, at lat. 71°15'15" N., long. 

 156°37'55" W., south-southwest of Pomt Barrow, 

 northern Alaska. 



Figured paratype (USNM P4306) from well cuttings 

 at 857-867 feet and unfigm-ed paratypes (USNM

 the Topagoruk formation, in Arcon Point Barrow core 

 test 1, at lat. 71°19'30" N., long. 156°40' W., north- 

 northeast of Barrow Village, northern Alaska. 



Unfigured paratypes (USNM P4308) from a core at 

 2,235-2,345 feet in the Topagoruk formation, in 

 Simpson test well 1, at lat. 70°57'05" N., long. 155°- 



21'45" W., west of Cape Simpson, northern Alaska. 

 Unfigured paratype (USNM P4309) from seismo- 

 graph party 47, line 14 A-48, shot hole 35, at 110-120

 long. 156°42'45" W., northern Alaska. 



Family Verneuilinidae Cushman, 1911 

 Genus Vemeuilinoides Loeblich and Tappan, 1949 



VemeuiUnoides borealia Tappan, new species 

 Plate 66, Figures 10-18 



Test free, elongate, triserial, axis commonly slightly 

 twisted, rounded in section, broadly flaring, rarely 

 more elongate and less flaring in the later portion; 

 chambers increasing rapidly in size, normally inflated, 

 but in many specimens the tests are crushed in 

 preservation; sutures distinct, depressed; wall com- 

 monly finely agglutinated, or may be relatively coarse 

 grained, probably reflecting the character of the local 

 depositional environment; aperture a low arch at the 

 base of the final chamber. 



Length of holotype 0.49 mm., breadth 0.18 mm. 

 Paratypes range in length from 0.26 to 1.17 nun. 



Remarks: This species is extremely variable in 

 size, degree of flaring, coarseness of texture, and type 

 of preservation. Commonly the specimens are crushed 

 and distorted, but more rarely specimens are filled with 

 pyrite, which preserves the original form and inflation 

 of the chambers. It is one of the most abundant 

 species in the northern Alaska strata. It differs from 

 Vemeuilinoides perplexa var. gleddiei Stelck and Wall 

 in being considerably larger and more flaring. 



V. borealis occurs in the Grandstand and Topagoruk 

 formations, in equivalent marine zones m the Chandler 

 formation, and in the upper part of the surface Torok 

 formation.
