12 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 128 



apertures numerous, a small rounded opening at the end of each of the 

 tubular extensions along the periphery ; color reddish brown. 



Types. — Topotype from paleontological collection in the Sorbonne, 

 Paris, France, from the collection of Dr. JuUien, 1887, Warabo or 

 Watabo, bank of Poor River, coast of Liberia, at 7 fathoms. 



Discussion. — Galloway (1933, p. 200) referred to this genus as 

 being chitinous, and Cushman (1948, p. 171) stated that it had a 

 flexible test. Neither statement seems to agree with the specimens. 

 Schlumberger stated that the wall consisted of siliceous sand grains 

 cemented by chitinous material, but he also stated that it had a very 

 resistant agglutinated test. The specimens we examined in Paris have 

 a very rigid test, agglutinated and with ferruginous cement with no 

 indication of "chitin." 



Genus MILIAMMINA Heron-Allen and Earland, 1930, emended 

 Plate I, figures 15, 16 



Original description. — Journ. Roy. Micr. Soc. London, ser. 3, vol. 

 50, p. 41, 1930. 



Type species. — Miliolina oblonga (Montagu) var. arenacea Chap- 

 man, 1916. Subsequent designation by Cockerell (1930, p. 975). 



Diagnosis. — Test free, chambers arranged in a quinqueloculine plan ; 

 wall siliceous, insoluble in hydrochloric acid, composed of minute min- 

 eral grains in an excess of siHceous cement, smoothly finished or 

 polished in appearance, more rarely roughened; aperture terminal, 

 with a tooth formed by the infolding of the wall. 



Types. — Chapman's type was from the Recent at 462 fathoms, lat. 

 y6°46' S., long. i63°26' E., Ross Sea, Antarctic. We were unable to 

 find this type in the collections of the British Museum. Our figures 

 are of the specimens of Heron-Allen and Earland, in the B.M.N.H. 



These specimens were included by Heron-Allen and Earland in 

 Chapman's species at the time they described the genus Miliammina. 

 However, in later publications they considered the South Georgia 

 form to be distinct from Miliammina arenacea (Chapman), differing 

 in a more ovate and rounded outline rather than having the parallel 

 sides of Chapman's species. Originally described as the variety are- 

 nacea of Miliolina oblonga (Montagu) by Chapman, it was incorrectly 

 referred to Miliammina oblonga (Chapman) by Heron- Allen and 

 Earland (1930, p. 41) and then to Miliammina arenacea (Chapman) 

 in later publications of Earland (1933, p. 92, and 1934, p. no). Also 

 Earland, considering their South Georgia form a separate species, 

 renamed it Miliammina oblonga Heron-Allen and Earland (1933, 

 p. 92), citing it again thus in 1934 (p. in).
