the inflated ovate chambers, their asymmetrical and 

 more elongate outline, and the greater range in size, 

 the smaller specimens possibly representing earlier 

 formed chambers. 



This species occurs in the Grandstand, Topagoruk, 

 and Fortress Mountain formations. The specific name 

 is in honor of R. L. Detterman, geologist, U. S. Geologi- 

 cal Siu-vey. 



Types and occueeence: Holotype (USNM P4556), 

 figured paratype (USNM P4557), and unfigured para- 

 types (USNM P4558), all from a core at 543-545 feet 

 in the Grandstand formation, in Simpson test well 1, at 

 lat. 70°57'05" N., long. 155°21'45" W., west of Cape 

 Simpson, northern Alaska. 



Figured paratype (USNM P4559) from weU cuttings 

 at 5,730-5,740 feet and unfigured paratypes (USNM 

 P4560) from well cuttings at 4,310-4,320 feet, all from 

 the Topagoruk formation, in Umiat test well 2, at lat. 

 69°23'04" N., long. 152°05'01" W., north of Umiat, in 

 the northern foothills of the Brooks Range, northern 

 Alaska. 



Figured paratype (USNM P4561) from the Fortress 

 Mountain formation (field sample 49A Pa 94), on the 

 north limb of Fortress Mountain syncline, along Fort- 

 ress Creek, tributary to the Ayiyak River, southwest of 

 Fortress Mountain, at lat. 68°35' N., long. 153°10' W., 

 in the southern foothills of the Brooks Range, northern 

 Alaska. Collected by W. W. Patton, Jr., 1949. 



Genus Rectoglandulina Loeblich and Tappan, 1955 



Rectoglandulina kirschneri Tappan, new species 



Plate 68, Figures 17, 18 



Test free, elongate, rectilinear, circular in section, 

 chambers increasing gradually in size from the conical 

 proloculus, early chambers closely appressed and over- 

 lapping, later more inflated and with less overlap, final 

 chamber turbinate in appearance; sutures distinct, 

 depressed, horizontal; wall calcareous, hyaline, finely 

 perforate, surface smooth; aperture terminal, radiate, 

 slightly produced on a neck. 



Length of holotj^pe 0.52 mm., breadth 0.23 mm. 

 Paratypes range from 0.34 to 0.94 mm. in length. 



Remarks: This species somewhat resembles Glandu- 

 lina elongata Reuss, 1860, from the Upper Cretaceous 

 (not G. elongata Bornemann, 1855) in general appear- 

 ance but is about one-third as large and has a conical 

 instead of a rounded proloculus. 



The species has been found in the Grandstand, 

 Topagoruk, and Oumalik formations. It is named in 

 honor of C. A. Kirschner, geologist, formerly with U. S. 

 Geological Survey. 



Types and occurrence: Holotype (USNM P4546) 

 from a core at 1,152-1,162 feet in the Topagoruk 

 formation, in Point Barrow core test 1, at lat. 71°19'30" 

 N., long. 156°40' W., southwest of Point Barrow, north- 

 ern Alaska. 



Unfigured paratype (USNM P4547) from a core at 



555-565 feet in the Grandstand formation and figured 

 paratype (USNM P4548) from weU cuttings at 4,870- 

 4,880 feet in the Oumalik formation, both 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 P4549) from a core at 

 1,625-1,630 feet in the Grandstand formation, in 

 Umiat test well 1, at lat. 69°23'52" N., long. 152°19'45" 

 W., in the northern foothills of the Brooks Range, 

 northern Alaska. 



Genus Saracenaria Defrance, 1824 

 Saracenaria dutroi Tappan, new species 



Plate 68, Fiqttbes 14-16 



Test free, early portion coiled, later \mcoiling and 

 rectilinear, triangular in section, periphery acute but 

 without a keel; chambers increasing rapidly in size 

 from the globular prolociflus, becoming increasingly 

 broader but enlarging very little in height, with con- 

 siderable overlap, so that final chamber is about half 

 again as high as the penultimate, sides of chambers 

 flattened or slightly depressed centrally, apertural face 

 flattened; sutures distinct, gently curved in the early 

 portion, more nearly straight but oblique in the later 

 portion, highest at the dorsal angle, wall calcareous, 

 hyaline, finely perforate, surface smooth; aperture ter- 

 minal at the dorsal angle, radiate, and slightly produced. 



Length of holotype 0.78 mm., greatest breadth of 

 side 0.31 mm., breadth of face 0.26 mm. Paratypes 

 range from 0.26 to 0.73 mm. in length. 



Remarks: Saracenaria dutroi, new species, differs 

 from S. saratogana Howe and Wallace in being relatively 

 narrower, with fewer and higher chambers, a more 

 enrolled base, and more acutely angled margins. 



This species occurs in the Grandstand and Topago- 

 ruk formations. The specific name is in honor of J. T. 

 Dutro, Jr., geologist, U. S. Geological Siu-vey. 



Types and occurrence: Holotype (USNM P4533) 

 from well cuttings at 1940-1950 feet in the Topagoruk 

 formation; unfigured paratypes (USNM P4534) from 

 a core at 438-443 feet, unfigiu-ed paratype (USNM 

 P4535) from a core at 493-503 feet, unfigiu-ed paratypes 

 (USNM P4536) from a core at 543-545 feet, all in the 

 Grandstand formation; figured paratype (USNM 

 P4537) from a core at 1,080-1,087 feet, unfigiu-ed para- 

 type (USNM P4538) from weU cuttings at 2,300-2,310 

 feet, and unfigured paratype (USNM P4539) from well 

 cuttings at 2,460-2,470 feet, all in the Topagoruk for- 

 mation; all in Simpson test well 1, at lat. 70°57'05" N., 

 long. 155°21'45" W., west of Cape Simpson, northern 

 Alaska.

 at 1,392-1,397 feet, in the Topagoruk formation, in 

 Arcon Pomt Barrow core test 1, at lat. 71°19'30" N., 

 long. 156°40' W., southwest of Point Barrow, northern 

 Alaska.
