BULIMINA PYHULA d'Orbigny, var. SPINESCENS H. B. Brady. 



Bulimina pyrula d'Orbigny, var. spinescens H. B. Brady, Eep. Voy. Challenger, 

 Zoology, vol. 9, 1884, p. 400, pi. 50, figs. 11, 12.— Cushman, Bull. 71, U. S. Nat. 

 Mus., pt. 2, 1911, p. 78, figs. 128, 129 (in te.xt). 



The only material wliich can be referred to tliis variety is a single 

 specimen from Albatross station, D5586, Sibiiko Bay, Borneo, 347 

 fathoms (635 metei-s), bottom temperature, 44° F. (6.4° C); and 

 D5638, south of Bouro Island, in 517 fathoms (946 meters). They 

 are of the form which I figured from off Japan, and are somewhat 

 different in shape than that figured by Brady. 



BULIMINA OVATA d'Orbigny. 



Bulimina ovata d'Orbigny, Foram. Foss. Vienne, 1846, p. 185, pi. 9, 

 figs. 13, 14. — n. B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, 

 1884, p. 400, pi. 50, figs. 13a, 6.— Cushman, Bull. 71, u". S. Nat. 

 Mus., pt. 2, 1911, p. 77, figs. 125a-c (in text). 



Specimens are rare at three stations all in 500 or more 

 fathoms (914 meters); D5201, Sogod Bay, southern Leyte, 

 in 554 fathoms (1,012 meters) ; D5469, east coast of Luzon, 

 in 500 fathoms (914 meters); and D5487, between Leyte 

 and Mindanao, in 732 fathoms (1,339 meters). The}^ are 

 also found at two other stations in 200 or more fathoms 

 (366 meters); D5216, between Burias and Luzon, 215 

 fathoms (393 meters); and D5591, Sibuko Bay, Borneo, 

 260 fathoms (476 metei-s). 

 This is a short species, in which even the last-formed chamber ex- 

 tends back to near the initial end of the test.
