PLANORBULINA ACERVALIS H. B. Brady. 



Planorbulina acervalis H, B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, 1884, 

 p. 657, pi. 92, fig. 4.— Flint, Rep. U. S. Nat. Mus., 1897 (1899), p. 328, pi. 72, 

 fig. 7.— CusHMAN, Bull. 71, U. S. Nat. Mus., pt. 5, 1915, p. 29, pi. 14, fig. 3. 



Compared with F. larvata this species is rare, being found at but 

 few stations and then represented by very few specimens. It oc- 

 curred at the following stations: D5191, in 258 fathoms (472 meters), 

 Tanon Strait, east coast of Negros, bottom temperature 62.8° F. 

 (17.1° C); D5255, in 100 fathoms (183 meters). Gulf of Davao; 

 D5419, in 175 fathoms (320 meters), between Cebu and Bohol, bot- 

 tom temperature 54.5° F. (12.5° C); D5469, in 500 fathoms (914 

 meters), east coast of Luzon; and D5546, in 138 fathoms (252 meters), 

 near Jolo Island, bottom temperature 58.3° F. (14.6° C). 



Brady's notes in regard to the distribution of this species con- 

 tains the following sentence: 



They frequent shallow water, and are moat plentiful on bottoms of less than 20 or 

 30 fathoms (37 or 55 meters), but are sometimes found at much greater depths. 



The Philippine material seemed to be represented in the shallow 

 water almost entirely by P. larvata, and the few records for P. acer- 

 valis are all from comparatively deep waters.
