chambered forms, but as they occurred with other 

 multilocular forms they may have represented young 

 individuals not yet completely developed, or may have 

 become separated in fossUization. The multilocular 

 Webbinelloidea is more characteristic of the Paleozoic 

 and the single-chambered Hemisphaerammina of the 

 Mesozoic and Cenozoic. 



HemisphaeraDunina batalleri Loeblich and Tappan, new species 

 Plate 72. Figure 3 



Test attached, consisting of a single, rounded to 

 ovate, inflated chamber attached by the flattened side; 

 wall agglutinated, of rather coarse grains with a 

 ground mass of finer material; no aperture visible. 



Greatest diameter of holotype 1.04 mm., least diam- 

 eter 0.88 mm., greatest diameter of paratype 0.83 mm. 



Remarks : This species di£f ers from Webbinella rugosa 

 ten Dam from the Albian of the Netherlands, in being 

 of considerably larger size, nearly three times as large, 

 and in lacking the narrow flattened border of W. rugosa. 



The specific name is given in honor of Dr. J. R. 

 Bataller of the University of Barcelona, Spain, in rec- 

 ognition of his oustanding work on the Cretaceous of 

 Spain. 



Types and occurrence: Holotype (USNM P3095) 

 and unfigm-ed paratype (USNM P3096) both from the 

 upper Santonian, near Casa Canellas, northeast of 

 Trago di Noguera, on the east bank of the Noguera 

 River, 16.5 km west of the main route between Trago 

 and Blancaforte, Province Lerida, Spain. Collected 

 by H. T. and A. R. Loeblich, Jr., with Dr. J. R. Ba- 

 taller, April 3, 1954. 



Hemisphaerammina bradyi Loeblich and Tappan, new species 

 Plate 72, Figure 2 



Webbina hemispherica Brady (not Jones, Parker and Brady 1866)i 

 Rep. Voy. Challenger, Zoology, vol.9, p. 350, pi. 41, fig.ll' 

 1884. 



Test attached, consisting of a single hemispherical 

 chamber; wall agglutinated, consisting of large angular 

 grains in a ground mass of finer particles, with much 

 cement; no visible aperture. 



Diameter of holotype 1.56 mm. According to Brady 

 other specimens range from 0.5 to 1.4 mm. in diameter. 



Remarks: As noted above, the holotype of Webbina 

 hemispherica Jones, Parker and Brady from the Plio- 

 cene is an attached polymorphinid and quite distinct 

 from the agglutinated forms later referred to that 

 species. The latter requires a distinct name and the 

 present species is therefore described. It differs from 

 Hemisphaerammina batalleri, new species, in being more 

 circular in outline, more inflated, and the suface more 

 smoothly finished. H. depressa (Heron-Allen and 

 Earland) has a more irregular outline and is less 

 inflated. 



Types and occurrence: Holotype (BMNH ZF2626) 

 is the specimen figured by Brady (pi. 41, fig. 11) and 

 is from the Recent deposits off Redcliff, Durham at 

 30 fathoms. 



A hypotype (USNM P3225) of Hemisphaerammina 

 depressa (Heron-Allen and Earland) is here figured 

 for comparison on plate 72, figure 1. It is from the 

 Recent, at Albatross station D4900, Ose Saki Light, 

 N. 10° E., 8 miles, lat. 32°28'50" N., long. 128°34'40" 

 E., at a depth of 139 fathoms. 



Family Textulariidae d'Orbigny, 1846 

 Zotheculifida Loeblich and Tappan, new genus 



Type species : Textvlaria lirata Cushman and Jarvis, 

 1929. Derivation: zothecula, L., f., diminutive of 

 zotheca, chamber or closet +.)?(i, L., suffix, denoting 

 division into parts; gender feminine.) 



Test free, compressed, elongate or palmate, chambers 

 numerous, biserially arranged with internal incomplete 

 partitions extending obliquely downward from the 

 septa, these partitions not visible externally on most 

 well preserved specimens, but may be seen when the 

 outer surface has either been dampened or somewhat 

 abraded, and in occasional rare specimens the secondary 

 partitions are visible externally as slightly darker than 

 the intervening spaces; wall agglutinated, fine grained, 

 rather smoothly finished; aperture a high narrow arch 

 at the base of the final chamber. 



Remarks: Zotheculifida, new genus, differs from 

 Tawitawia Loeblich in the more numerous and regularly 

 arranged internal partitions and in possessing a single 

 textularian aperture rather than the terminal linear 

 series of pores. It differs from Poritextularia Loeblich 

 and Tappan in the presence of the internal partitions 

 and in possessing only a single aperture. From Textu- 

 laria Defrance it is differentiated by the internal 

 secondary partitions.

 . Textularia lirata Cushman and Jaevis, Contr. Cushman Lab. 

 Foram. Res., vol. 5, p. 6, pi. 2, figs. 4a,b, 1929. 



Test free, greatly compressed, margins subacute, 

 palmate in outline; chambers numerous, biseriaUy 

 arranged, up to eight or nine pair, strongly recurved 

 laterally with height about one-fourth their breadth, 

 siu-face slightly excavated; sutures distinct, limbate 

 and raised above the level of the chamber surface, 

 strongly arched, internally the septa have numerous 

 pendant partial secondary partitions which are radially 

 arranged, being nearly vertical near the plane of bi- 

 seriality and horizontal or even recurved at the outer 

 margins; wall finely agglutinated, rather smoothly 

 finished; apertui-e a high narrow arch about fom- times 

 as high as broad, at the base of the last chamber. 



Remarks: In describing this species, Cushman and 

 Jarvis (1929, p. 6), on the basis of a single incomplete 

 specimen, stated that the chambers were somewhat 

 spinose at the periphery and that the surface showed 

 oblique furrows in the outer portions of each chamber. 

 The "spinose periphery" is not always present, occmT- 

 ing only in greatly compressed specimens and the 

 "oblique furrows" are actually the siu'face reflection of
