 Albatross station D5236, in 494 fathoms (903 metei's), Pacific Ocean, 

 east coast of Mindanao.

QUINQUELOCULINA LLMBATA d'Orbigny. 



QuinquelocuUna limbata d'Orbigny, Ann. Sci. Nat., vol. 7, 1826, p. 302, No. 20. — 

 FoRNASiNi, Mem. Accad. Sci. Bologna, ser. 6, vol. 2, 1905, p. 66, pi. 3, fig. 9. 



Miliolina limbata Heron-Allen and Earland, Trans. Zool. Soc. London, vol. 

 20, 1915, p. 577, pi. 44, figs. 5-8. 



D'Orbigny's original specimens are from the Red Sea, and this 

 seems to be a species with Indo-Pacific distribution. Heron-Allen 

 and Earland had it from the Kerimba Archipelago, and it has oc- 

 curred at two stations, D5313, China Sea off Hongkong, 150 fathoms 

 (275 meters), and D5369, off Marinduque Island, 106 fathoms (194 

 meters), in the Philippine material. 



The specimens have the highly polished surface characteristic of 

 this species.
