There are two sorts of specimens in the material, one of these evi- 

 dently the megalospheric form, in which the proloculum is large and 

 followed by a long, straight chamber, sometimes constricted ones. 

 The other is evidently the microspheric form, the proloculum and 

 initial end usually wanting, and represented by a series of gradually 

 enlarging subcyhndrical chambers. 



Brady records this species from 95 fathoms (174 meters) from the 

 Philippines in the Challenger material. 



The only material I have had has come from the following stations: 

 D5201, Sogod Bay, southern Leyte, in 554 fathoms (1,012 meters), 

 and D5236, Pacific Ocean, east coast of Mindanao, in 494 fathoms 

 (1,086 meters).

Genus QUINQUELOCULINA d'Orbigny, 1826. 



This genus contains probably more specimens of various species than 

 any other in the entire Philippine foraminifera. The species are 

 numerous and many of them very definite, both in their characters 

 and their geographical distribution. 



They seem to fall into three different groups: First, those which 

 occur in the deeper water and which are found in otlier regions and rep- 

 resent widely distributed species. These are usually few in number, 

 as far as specimens occur, and are widely scattered in the region where 

 sufficient depth is obtained, especially on the ocean side of the islands, 

 and in the region southward where the Albatross dredged. The
