NO. 5 FORAMINIFERAL GENERA — LOEBLICH AND TAPPAN II 



Genus TEXTULARIOIDES Cushman, 191 1, emended 

 Plate I, figures 4, 5 



Original description. — U. S. Nat. Mus. Bull. 71, p. 26, 1911. 



Type species. — Textularioides inflafa Cushman, 1911. Original 

 designation. 



Diagnosis. — Test attached at least in the early stages; chambers in 

 a biserial textularian arrangement, somewhat flattened against the 

 attachment, later portion often growing free of the attachment ; wall 

 agglutinated, with coarse grains embedded in a fine ground mass which 

 is pierced by numerous tiny pores connecting the interior to the ex- 

 terior ; aperture a low arch or slit at the base of the final chamber. 



Types and discussion. — Originally the genus was known from the 

 holotype of the type species (U.S.N.M. No. 8337) from Albatross 

 station D 4900, in 139 fathoms, ofif the coast of Japan. A prolonged 

 search through the original sample by the writers has supplied a num- 

 ber of topotypes (U.S.N.M. No. 560423) which bring out additional 

 characters not originally descril^ed. The specimen here illustrated, 

 figure 4 (U.S.N.M. No. P 2196a), shows the final two pairs of 

 chambers growing free of the attachment, and the typical low, slitlike 

 aperture. Another specimen (fig. 5), which is broken free of the 

 attachment, shows on the attached side the radial wall structure 

 pierced by many pores. This type of structure has been noted in other 

 agglutinated forms (see Wood, 1949, p. 234) such as Tritaxia capre- 

 olus Brady, Textularia porrecta Brady, and Textularia rugosa Reuss, 

 and is undoubtedly more common in the agglutinated forms than has 

 been suspected in the past. 



Genus JULLIENELLA Schlumberger, 1890 

 Plate I, figures 13, 14 



Original description. — Soc. Zool. France, Mem., vol. 3 (1890), pt. 

 I, p. 213, 1889. 



Type species. — Jullienclla foetida Schlumberger, 1890. Monotypic. 



Diagnosis. — Test large, flabelliform, occasionally with large fan- 

 shaped portions extending in two directions from a central attachment, 

 margin produced into numerous tubules, interior irregularly sub- 

 divided by a series of intermittent radiating ridges, which are not 

 reflected on the exterior (fig. 14b) ; interior surface has many large 

 pores, which apparently connect with much more restricted openings 

 at the surface, wall firm, finely arenaceous, with much ferruginous 

 cement, insoluble in hydrochloric acid, surface transversely wrinkled ;
