somewhat thickened on the spiral side, nearly straight 

 and radial on the umbilical side; wall calcareous, finely 

 perforate, surface smooth to lightly spinose; aperture 

 interiomarginal, extraumbUical-umbilical, a low arch 

 which may show a narrow bordering lip. 



Hypotypes range in diameter from 0.20 to 0.38 mm. 

 and in thickness from 0.11 to 0.23 mm. 



Remarks: Globorotalia pusilla laevigata Bolli from 

 the Paleocene of Trinidad is a very similar form and 

 undoubtedly related to the present species. 



Globorotalia pseudoscitula differs from G. convexa Sub- 

 botina in being more lenticular in section, with a more 

 convex spiral side rather than a flattened one and a less 

 inflated umbilical side, with nearly closed umbilicus. 



Types and occukbence: Figured hypotype (USNM 

 P5139) from the Vincentown formation, north bluff of 

 Rancocas Creek, 0.3 to 0.5 miles north of Vincentown, 

 Burlington County, New Jersey. Collected by A. R. 

 Loeblich, Jr., and Norman Sohl. 



Figured hypotype (USNM P5130) from the Aquia 

 formation, 15 to 17 feet above the base of the section 

 exposed, west bank of Potomac River near mouth of 

 Aquia Creek, S. 10° E. of Brent Point on U. S. Geo- 

 logical Survey Nanjemoy Md.-Va. Quadrangle, 1: 63,500, 

 1913, reprinted 1945. 



Figured hypotype (USNM P5140) from the Salt 

 Mountain limestone, in a limestone sink M mile north 

 of Salt Mountain, in the NW}^NWK, Sec. 34, T. 6 N., 

 R. 2 E., Clarke County, Alabama. Collected by H. T. 

 and A. R. LoebHch, Jr. 



Figured hypotype (USNM P5895) from the Velasco 

 formation, middle bed at road crossing of arroyo half- 

 way between San Jose de las Rusias and Soto la Marina, 

 Tamaulipas, Mexico. Collected by R. Wright Barker. 



Figured hypotype (USNM P5870) from the Coal 

 Bluff marl member of the Naheola formation, in creek 

 bottom just west of store at Caledonia, about Vi mile 

 south of center of Sec. 29, T. 11 N., R. 10 E., Wilcox 

 County, Alabama. Collected by F. Steams MacNeil. 



Globorotalia pseudotopilensis (Subbotina) 

 Plate 60, Figtjbes 2a-c 



Acarinina pseudotopilensis Subbotina, Trudy Vses. Neft. 

 Naukno-Issledov. Geol.-Razved. Inst., new ser. vol. 76, 

 p. 227, pi. 21, figs. 8, 9; pi. 22, figs. 1-3, 1953. 



Test free, trochospiral, inflated, periphery broad* 

 sub truncate but not angular, peripheral outline lobu- 

 late, with final chamber broadest somewhat above its 

 base and presenting a trapezoidal appearance, lunbiUcus 

 smaU, umbihcal shoulder rounded; chambers in about 

 two whorls, 4 in the final whorl, final chamber com- 

 prising about one-third of the test; sutures distinct, 

 nearly radial and constricted on both sides; wall cal- 

 careous, finely perforate, hispid in appearance, covered 

 with prominent blunt spines, which are strongest in 

 the peripheral area ; aperture an arched interiomarginal 

 extraumbilical opening. 



Greatest diameter of figured hypotype 0.30 mm. 



Remarks: This species was originally described from 

 the Paleocene and lower Eocene of Russia. It occurs 

 rarely in the Nanafalia formation {Ostrea thirsae beds) 

 of Alabama. 



Globorotalia psevdotopilensis differs from G. angulata 

 (White) in the rounded margins, instead of having a 

 peripheral keel, in the much more strongly spinose 

 surface, and more elevated chambers. 



Types and occuekencb: Figured hypotype (USNM 

 P5869) from the NanafaHa formation, south valley 

 wall of Shoal Creek, 5.5 miles southeast of Camden, 

 along the Camden-Fatama road, Wilcox County, 

 Alabama. Collected by A. R. Loeblich, Jr. 



Globorotalia reissi Loeblich and Tappan, new species 

 Plates 50, Figures 3a-c; 58, Figubes 3a-c; 60, PiGUBEs7a-c 



Test free, trochospiral, periphery subangular, periph- 

 eral outline lobulate, strongly convex on the spiral 

 side where the 2K whorls may be seen with the early 

 whorls raised distinctly above the level of the 5 to 6 

 chambers in the final whorl; chambers of greater 

 breadth than height, increasing gradually in size as 

 added; sutures distinct, depressed, sHghtly curved on 

 the spiral side, radial on the umbihcal side; wall cal- 

 careous, finely perforate, surface smooth; aperture a 

 low extraumbilical-umbUical arch, with a narrow 

 bordering lip above. 



Greatest diameter of holotype 0.16 mm. 



Remarks: This species is closest in appearance to 

 G. perclara, new species, but differs in the more elevated 

 spire, and smooth rather than spiaose surface. It 

 differs from G. imitata Subbotina in the more lenticular 

 form, with subglobular periphery, and the more 

 numerous chambers per whorl. 



The specific name is in honor of Dr. Z. Reiss, micro- 

 paleontologist. Geological Survey of Israel. 



Types and occurrence: Holotype (USNM P5835) 

 from the Aquia formation, to 3 feet above base of the 

 exposm-e, west bank of Potomac River, near mouth of 

 Aquia Creek, S. 10° E. of Brent Point on U. S. Geologi- 

 cal Survey Nanjemoy Md.-Va. Quadrangle, 1:62,500, 

 1913, reprinted 1945. Collected by A. R. Loeblich, 

 Jr., and Richard A. Page. 



Figured paratype (USNM P5836) from the Homers- 

 town formation, north bank of Shingle Rim, a tributary 

 to Crosswicks Creek, 1.0 mile north of New Egypt, 

 Moimaouth County, New Jersey. Collected by A. R. 

 LoebHch, Jr., and Norman Sohl. 



Figured paratype (USNM P5837) from the Nana- 

 faHa formation, south valley waU of Shoal Creek, 5.5 

 miles southeast of Camden, on the Camden-Fatama 

 road, Wilcox County, Alabama. Collected by A. R. 

 LoebHch, Jr. 



This species also occurs in the Coal Bluff marl 

 member of the Naheola formation of Alabama and 

 the Matthews Landing marl member of the Porters 

 Creek clay of Alabama.
