Not illustrated. 1917 edition. Excerpt: ...peripheral margin broadly rounded, last formed chamber not exserted at the apertural end, surface ornamented 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). Plate 15, fig. 3. "Quinqueloculina with oblique ridges" Parker, Trans. Micr. Soc. London, vol. 6, 1858, p. 53, pl. 5, fig. 10. Miliolina parkeri H. B. Brady, Quart. Journ. Micr. Sci., vol. 21, 1881, p. 46; Rep. Voy. Challenger, Zoology, vol. 9,1884, p. 177, pl. 7, fig. 14. Description.--"Test elongate, sub triangular, quinqueloculine; peripheral margins of the segments sharp, with a tendency to become carina to; 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, essentially 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. Khumbler 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 specimens...show more
