FOKAMINIFERA OF THE PHILIPPINE AND ADJACENT SEAS. 397 



The depths range from 10 to 554 fathoms (18 to 1,012 meters), 



the average, however, being about 70 fathoms (128 meters). The 



bottom temperatures where given range from 43.3° to 75.7° F. (6.1° to 



24.2° C), with the average 58.3° F. (14.6° C). This is too low, 



however, as it is only from eight of the deeper stations. Both sets 



of data show that the species is most at home in shallow, very warm 



waters .

SPIROLOCULINA GR.iTELOUPI d'Orbigny, rar. INCISA. new variety. 



Plate 78, fig. 5. 



Description. — Variety differing from the typical in the adding of 

 the chambers, the inner margin of the newly added chamber not 

 being equal to the outer margin of the preceding chamber, thus 

 leaving a distinct sharp ridge between each of two chambers as 

 added. This leaves a series of incised areas with high areas alter- 

 nating with them. 



Distrihution— Type specimen (Cat. No. 10941, U.S.N.M.) from 

 Albatross station D5220, between Marinduque and Luzon, in 50 

 fathoms (91 meters). It has also occurred at six other stations: 

 Off Komblon; off western Samar; between Burias and Luzon; 

 Palawan Passage; and off Marinduc[ue.
