TROPICAL PACIFIC FORAMINIFERA OF ALBATROSS 21 



Miliolina costata Hebon-Aixkn and Eaeland, Trans. Zool. Soc. London, vol. 20, 

 pt. 2, p. 579, pi. 44, figs. 9-12, 1915. 



Test elongate, two to three times as long as broad, periphery 

 usually rounded; chambers distinct, inflated; sutures somewhat de- 

 pressed ; wall ornamented by numerous fine longitudinal costae, often 

 slightly oblique to the axis of the chamber; aperture at the end of 

 a short neck, with a slight lip, and single short tooth. Length, 

 0.35-0.5 mm. ; breadth, 0.15-0.25 mm. ; thickness, 0.1-0.12 mm. 



The types of d'Orbigny's species are from the Mediterranean. 

 Forms such as those figured here occur rather abundantly in our 

 material from Vavau Anchorage, Tonga Islands, from which the 

 figured specimens came, and from the following Fiji Islands local- 

 ities: 12 fathoms off Levuka; 3 fathoms, Viva Anchorage; Mokaujar 

 Anchorage; and near Nairai. It was also common in 7 fathoms 

 at Rotonga.

 QuinquelocuHna crassa Cushman (not d'Orbigny), Carnegie Inst. Washington 



Publ. 344, p. 82, 1926. 



Test similar to the typical form in ornamentation but short, and 

 the chambers wedge-shaped, almost sharp at the peripheral angles. 



This variety, originally described from the Philippines, occurs 

 widely distributed in the Indo-Pacific and also extends into the 

 Atlantic. 



The form is not common in our material, but occurs rarely off 

 Levuka, Fiji Islands, in 12 fathoms; Vavau Anchorage, Tonga 

 Islands, 18 fathoms; off Rotonga, 7 fathoms; Port Lotten, Kersail, 

 Caroline Islands ; and Rongelap Atoll, Marshall Islands. 



QUINQUELOCULINA CRENULATA, new species 



Plate 5, Figures 11 a-c 



Test elongate, slender, about three times as long as broad ; chambers 

 distinct, not much inflated; sutures distinct; wall ornamented by 

 numerous very coarse, obliquely curved, short costae, extending in- 

 ward from the peripheral angle, and sloping toward the base of the 

 chamber, six at the base of the last-formed chamber sometimes form-
