Genus AMMOBACULITES Cushman, 1910. 



AMMOBACULITES AGGLUTINANS (d'Orbigny). 



Spirolina agglutinans d'Orbigny, Foram. Foss. Vienne, 1846, p. 137, pi. 7, figs. 



10-12. 

 Haplophragmium agglutinans H. B. Brady, Rep. Voy. Challenger, Zoology, vol.

 Ammohaculites agglutinans Oushman, Bull. 71, U. S. Nat. Mus., pt. 1, 1910, p. 

 115, fig. 176 (in text). 



Five specimens seem to be referable to this species. They are 

 not typical but are like the specimen figured on page 115/ the coiled 

 portion not being very distinct from the later uncoiled portion. 

 This same characteristic has been noted in the Phihppine and other 

 Pacific specimens, and they represent a different form from that 

 described by d'Orbigny. 



Genus TROCHAMMINA Parker and Jones, 1860. 



TROCHAMMINA cf. NANA H. B. Brady. 



There are three specimens in this material which are very close to 

 this species as figured by Brady. The wall is very smooth, composed 

 of an abundance of cement and scattered clear sand grains. Side- 

 bottom^ records this species. 



TROCHAMMINA SQUAMATA Parker and Jones (7), 



There are several specimens attached to shell fragments which are 

 probably this species. The wall is made of sponge spicules, small 

 angular quartz grains and fine, nearly white, cement. The surface 

 is smoothly finished. Heron-Allen and Earland record this species 

 from the Kerimba Archipelago, speaking of it as "nearly white in 

 color." This is probably the same species as theirs from that region. 

 Most of the specimens are surrounded by a considerable amount of 

 amorphous material. 



Genus AMMOSPHAEROIDINA Cushman, 1910. 



AMMOSPHAEROIDINA SPHAEROIDINIFORMIS (H. B. Brady). 



Navlophragmium sphaeroidiniformis 11. B. Brady, Rep. Voy. Challenger, Zoology, 



vol. 9, 1884, p. 313. 

 Ammosphaeroidina sphaeroidiniformis Cushman, Bull. 71, U. S. Nat. Mus., pt. 1, 



1910, p. 128, fig. 202 (in text). 



A single specimen, evidently this species, occurs among the 

 mounted material.
