Figs. 1-4, 6-14, X 10; Fig. 5, X 20; Figs. 15-19, X 16. 

 Figures 1-3, 5, 6. — Hyperammina friabilis Brady. 



Fig. 1. Challenger Sta. 122, S.E. of Pernambuco. (350 fathoms) 

 Fig. 2. Porcupine Sta. 47, Faroe Channel, N. Atlantic. (542 fathoms) 

 Fig. 3. Challenger Sta. 195, Banda Sea, Pacific. (1425 fathoms) 

 Fig. 6. Porcupine Sta. 47, Faroe Channel, N. Atlantic. (542 fathoms) 

 Figures 4, 7. — Hyperammina cylindrica Parr. 



Fig. 4. Off Cumbrae, N. Atlantic. (60-65 fathoms) 

 Fig. 7. Challenger Sta. 323, S. Atlantic. (1900 fathoms) 

 Referred by Brady to Hyperammina elongata Brady. Parr, B.A.N.Z. Antarctic Res. Exped., p. 254, 1950, 

 placed these in H. cylindrica. 

 Figure 8. — Hyperammina elongata Brady.* 



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

 Figures 9, 10. — Hyperammina laevigata Wright. 



Challenger Sta. 323, South Atlantic. (1900 fathoms) 

 Referred by Brady to Hyperammina elongata Brady. Wright described H. laevigata as a variety of H. 

 elongata Brady in 1891 and Cushman in 1910 (U.S.N. M. Bull. 71, Pt. 1, p. 61) referred Brady's figures 9, 10 

 to the variety. In 1918 Cushman (U.S.N.M. Bull. 104, Pt. 1, p. 77) raised the variety to specific rank. 

 Figures 11-14. — Hyperammina subnodosa Brady. 



Referred in text to N. Atlantic, East Indies and Pacific. 

 Figures 15-19. — Saccorhiza ramosa (Brady). 



Figs. 15, 17-19. Porcupine Sta. 23, N.W. of Ireland. (630 fathoms) 

 Fig. 16. Challenger Sta. 246, North Pacific. (2050 fathoms) 

 Referred to Hyperammina by Brady. Placed in Saccorhiza by Eimer and Fickert, Zeitschr. Wiss. Zool., 

 Vol. 65, 1899, p. 670. 



*NoTE: Hyperammina elongata Brady was cited by Eimer and Fickert for their new genus Bactrammina (Zeitschr. Wiss. Zool., Vol. 65, 

 1899, p. 601) but this genus has been relegated to the synonymy of Hyperammina by Cushman, Galloway and other workers.
