EXPLANATION OF PLATE 33 (XXXIII) 



Figs. 1-4, X 35; Figs. 5-12, X 18; Figs. 13-16, X 25; Figs. 17-19, X 35; 

 Figs. 20-25, X 40; Figs. 26-28, X 25. 

 Figures 1-4. — Ammoscalaria pseudospiralis (Williamson). 



Fig. 1. Porcupine Sta. 1, West of Ireland. (370 fathoms) 

 Figs. 2-4. Porcupine Sta. AA, Skye, W. of Scotland. (45-60 fathoms) 

 Referred by Brady to Haplophragmium pseudospirale and by Hofker (Pubbl. Staz. Zool. Napoli, Vol. 12, 

 1932, p. 87) to Ammobaculites prostomum, pointing out that they are not in accord with Williamson's descrip- 

 tion (test thin, compressed, . . . test coarsely arenaceous and granular . . . etc.). Hoglund (1947, Zool. Bidr. 

 fr. Uppsala, Vol. 26, pp. 159-162) and Parker, Phleger and Peirson (1953, Cushman Found. Foram. Res., 

 Spec. Publ, No. 2, p. 6) do not agree with Hofker, and place his prostomum in the synonymy of pseudospiralis 

 (Williamson) in Hoglund's genus Ammoscalaria. 

 Figures 5, 7-12. — Ammobaculites calcareus (Brady). 



Figs. 5, 8, 12. Challenger Sta. 24, West Indies. (390 fathoms) 

 Figs. 7, 9-11. Challenger Sta. 185, Torres Strait, Pacific. (155 fathoms) 

 Referred to Haplophragmium by Brady. It seems probable that figs. 7, 9-11 may represent a diflferent species 

 from figs. 5, 8 and 12, as the form and texture are entirely different, and moreover one is a West Indian species 

 and the other from the tropical Pacific. It is suggested that the name A. calcareus be restricted to the West 

 Indian species (figs. 5, 8, 12). 

 Fig. 6. — "Ammobaculites cylindricus Cushman." 



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

 Haplophragmium calcareum, part, of Brady. See Cushman, 1910, Proc. U.S.N.M., Vol. 38, p. 441, figs. 15, 

 16. It would appear that Cushman was in error in referring this figure of Brady to his .4. cylindricus. 

 Fig. 6 is regarded as Ammobaculites calcareus (Brady). 

 Figures 13-16. — Ammoscalaria tenuimargo (Brady). 



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

 Referred by Brady to Haplophragmium and by Hoglund (Zool. Bidr. fr. Uppsala, Vol. 26, 1947, p. 154) 

 to Ammoscalaria. 

 Figures 17-19. — Ammotium cassis (Parker). 



Gaspe Bay, Mouth of St. Lawrence River, Canada. (16 fathoms) 

 Referred by Brady to Haplophragmium and by Cushman (U.S.N.M. Bull. 104, Pt. 2, 1920, p. 63) to Am- 

 mobaculites. Loeblich and Tappan (Smiths. Misc. Coll., Vol. 121, No. 7, 1953, p. 33) made this the genotype of 

 Ammotium. 

 Figures 20-25. — Ammomarginulina foliaceus (Brady). 



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

 Referred by Brady to Haplophragmium and by Cushman (U.S.N.M. Bull. 104, Pt. 2, 1920, p. 64) to Am- 

 mobaculites. It was figured by Cushman in 1933 as Ammomarginulina (C.L.F.R., Spec. Publ. No. 4, pi. 10, 

 figs. 6a-b). 

 Figures 26-28. — Discammina compressa (Goes). 



Fig. 26. Challenger Sta. 24, West Indies. (390 fathoms) 

 Figs. 27, 28. Challenger Sta. 23, West Indies. (450 fathoms) 

 Referred by Brady to Haplophragmium emaciatum Brady and by Cushman (U.S.N.M. Bull. 71, Pt. 1, 

 1910, p. 102) to Haplophragmoides emaciatum (Brady). However Goes (Bull. Mus. Comp. Zool. Harvard, 

 Vol. 29, No. 1, 1896, p. 31) placed this species in the synonymy of Haplophragmium compressum (Goes) (de- 

 scribed as Lituolina irregularis Roemer var. compressa by Goes in 1882. This synonymy was accepted by 

 Millett (Jour. Roy. Micr. Soc, 1899, p. 359) and Heron-Allen and Earland (Trans. Zool. Soc. London, Vol. 

 20, Pt. 17, 1915, p. 613) and discussed in detail by Lacroix (Bull. I'lnst. Oceanogr. Monaco, No. 667, 1935, 

 p. 15) who placed it in the genus Discammina Lacroix 1932.
