Textularia concava, var. heterostoma FornaBini. 



Sagraina affinis Fornasini, 1883, Boll. Soc. Geol. Ital., vol. ii, p. 189, pi. ii, 



fig. 10. 

 Textularia heterostoma Fornasini, 1896, Mem. R. Accad. Sci. Istit. di 



Bologna, Ser. 5, vol. vi, p. 4, pi. figs. 6, 12, 13. 



A single example, agreeing well with Fornasini's (1888) illus- 

 tration, fig. 1, a-c, excepting that the orifice is not set at an angle, 

 and is placed as in T. concava Karrer. 



Textularia striata Cushman. 



Textularia striata Cushman, 1911, Foram. North Pacific Ocean, Smithsonian 

 Instit. U.S. Nat. Mus. Bull. 71, Text, p. 11, fig. 13. 



Four occur, the largest having about forty chambers. They 

 agree accurately witli Cushman's description, excepting that the 

 apertural end is not "somewhat acute." The same large tests 

 occur at the " Challenger " St. 185, off Eaine Island, but they are 

 very roughly built. 



Further investigation may prove that these are a variant of 

 Textularia agglutinans, var. forrecta Brady. 



Cushman's species appears to be identical with the forms 

 recorded and figured by Chapman from Great Barrier Island, New 

 Zealand, 110 fathoms, under tlie names Spiroplccta sagittida 

 (Defrance), and S. sagittula, var. fistulosa Brady (Chapman, 1906,. 

 Trans. N. Zealand Instit., vol. xxxviii (1905), p. 87, pi. iii, fig. 4). 

 It is a very large form, typical of the " Thomson Basin," and 

 abundant in dredgings from this area. The early structure is in 

 our experience usually, if not invariably, Spiroplectine, and Cush- 

 man's figure suggests a Spiroplectine form, though his description 

 contains no reference to this feature. But the " Dart " specimens 

 are of a megalospheric Textularian type, and this would seem to 

 be proof of dimorphism. The species deserves to be carefully 

 worked out. 



Textularia quadrilatera Schwager. 



Textularia quadrilatera Schwager, 1866, Novara-Exped. Geol. Theil., 



vol. ii, p. 253, pi. vii, fig. 103. 

 T. quadrilatera, Brady, 1884, Chali. Kept., p. 858, pi. xlii, figs. 8-12. 



Excellent specimens occur, none of which are spinous at the 

 base. 



Textularia incon8j)icua Brady. (PI. II, figs. 19-21.) 



Textularia tncons^tcw a Brady, 1884, Chall. Kept., p. 357, pi. xlii, fig. 6. 



T. inconspicua Millett, 1898, etc., Kept. Foram. Malay Archipelago, Journ. 

 Eoy, Micr. Soc, 1899, p. 557, pi. vii, fig. 1. 



T. inconspicua Heron-Allen and Earland, 1915, Foram. Kerimba Archi- 

 pelago, Zool. Soc. London, vol. xx, pt. xvii, p. 623, pi. xlvii, figs. 1-4. 



Typical tests are present. Besides these, there are a few 

 having the base irregular, or nearly so, in outline. One can see
