EXPLANATION OF PLATE 1 (I) 



Figs. 1-8, X 50; Figs. 9-15, 17, X 20; Fig. 16, X 25; Fig. 18, X 30; Figs. 19, 20, X 45. 

 Figures 1-4. — Nodophthalmidium sp. nov. 



Fig. 1. Challenger Sta. 24, West Indies. (390 fathoms) 

 Figs. 2-4. Challenger Sta. 21 7A, off Papua, Pacific. (37 fathoms) 

 Referred by Brady to Nubecularia tibia Jones and Parker ( N. lucifuga Defr. var. tibia of Jones and Parker). 

 Rhumbler (Nachr. K. Ges. Wiss. Gottingen, 1895, Heft 1, p. 87) proposed the genus Nodobacularia and Cush- 

 man (1917) designated iV. tibia the genotype. Macfadyen (Jour. Roy. Micr. Soc, Ser. 3, Vol. 59, 1939, p. 167) 

 has shown that N. tibia is a synonym of Bullopora rostrata Quenstedt, and is a Jurassic species. The Recent 

 forms figured by Brady were placed by Macfadyen in Nodophthalmidium and require a new specific name. 

 Figures 5, 6. — Parrina bradyi (Millett). 

 Figures 7, 8. — Parrina bradyi (Millett) var. sufflata Rhumbler. 



Figs. 5-8. Challenger Sta. 260A, off Honolulu reefs. Pacific. (40 fathoms) 

 Referred by Brady to Nubecularia inflata (figs. 5-8). As inflata was preoccupied (Terquem 1876), Millett 

 (Jour. Roy. Micr. Soc, 1898, p. 261) proposed the name bradyi. Schubert (Pal. Zeitschr., Vol. 3, 1920, p. 166) 

 proposed the genus Silvestria, with type N. bradyi Millett, but since Silvestria was preoccupied by Verhoeff 1895, 

 Cushman (C.C.L.F.R., Vol. 7, 1931, p. 20) proposed the name Parrina. Rhumbler (Kiel Meeresf., Vol. 1, 

 1936, p. 197) split Brady's species into two varieties, fistulata (figs. 5, 6) and sufflata (figs. 7, 8). It appears 

 unnecessary to make use of two varietal names, and the name bradyi has therefore been retained for Rhum- 

 bler's bradyi var. fistulata (figs. 5, 6), leaving figs. 7 and 8 as bradyi var. sufflata Rhumbler. 

 Figures 9-11, 13-16. — Nubecularia lucifuga Defrance. 

 Gulf of Bombah, Tripoli, Mediterranean. 

 This is the type of Nubecularia. 

 Figure 12. — Nubecularia lucifuga Defrance var. lapidea Wiesner. 

 Gulf of Bombah, Tripoli, Mediterranean. 

 Referred by Brady to Nubecularia lucifuga and by Howchin and Parr (Trans. Roy. Soc. S. Australia, Vol. 

 62, No. 2, 1938, p. 297) to N. lucifuga Defrance var. lapidea Wiesner (Die Miliolideen der ostlichen Adria, 

 Prague, 1923, p. 94). 

 Figures 17, 18. — Nummoloculina irregularis (d'Orbigny). 



Fig. 17. Challenger Sta. 23, West Indies. (450 fathoms) 

 Fig. 18. Challenger Sta. 85, off the Canaries, Atlantic. (1125 fathoms) 

 Referred by Brady to Biloculina and by Cushman (U.S.N.M., Bull. 104, Pt. 6, 1929, p. 46) to Nummo- 

 loculina. 

 Figures 19, 20. — Triloculina cuneata Karrer, "biloculine variety." 

 Off Tripoli, Mediterranean. 

 Above is the determination given by Brady, and his material may not be identical with the Tertiary species 

 described by Karrer. Brady's figures show a more inflated form than those of Karrer and may be a variety or 

 possibly new.
