QUINQUELOCULINA BOUEANA d'Orblgny. 

 Plate 15, fig. 2. 



Quinqueloculina boueana d'Oebigny, Foram. Foss. Bass. Tert. Vienne, 1846, p. 



293, pi. 19, figs. 7-9. 

 Miliolina boueana H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, 1884, 



p. 173, pi. 7, figs. 13a-c. 



Description. — Test nearly as broad as long, chambers broad, dis- 

 tinct, sutures depressed, peripheral margin broadly rounded, last 

 formed chamber not exserted at the apertural end, surface orna- 

 mented with numerous, distinct, longitudinal costae, aperture nearly 

 circular, lip slightly thickened, with a simple tooth. 



Length, usually less than 1 mm. 



Distribution.— This species has occurred at Nero station 2041 in 

 33 fathoms in the vicinity of the Hawaiian Islands, Nero station 1466 

 off Guam in 234 fathoms, and at Albatross station D4900 in 139 

 fathoms off the coast of Japan. 



QUINQUELOCULINA PARKERI (H. B. Brady).

 Miliolina parkeri H. B. Brady, Quart. Journ. Micr. Sci., vol. 21, 1881, p. 46; 



Rep. Voy. Challenger, Zoology, vol. 9, 1884, p. 177, pi. 7, fig. 14. 



Description. — "Test elongate, subtriangular, quinqueloculine; 

 peripheral margins of the segments sharp, with a tendency to become 

 carinate; the surface of the chambers traversed by somewhat oblique 

 transverse ridges or crenulations. 



"Length, one twenty-fifth inch (1 mm.)." 



Distribution. — This species seems to be, as noted by Brady, essen- 

 tially a coral-reef species. In his tables of distribution he includes 

 it from Challenger station 260A, in 40 fathoms off the coral reefs of 

 Honolulu, Hawaiian Islands. Bagg also records it from this same 

 region, Albatross D4000, in 104 to 213 fathoms, H4566, in 572 fathoms, 

 and H4694 in 865 fathoms.* Rhumbler records it from Laysan 

 Island, a single specimen. I have examined Bagg's mounted material 

 from the Hawaiian Islands, and it appears to be typical. In the 

 material I have had from this same region I have found it but once, 

 in material from Nero station 2039, in 24 fathoms. Typical speci- 

 mens occur in shallow water material from Apra Bay, Guam, and 

 from Gaspar Straits.
