QUINQUELOCULINA BICARINATA d'Orbigny. 



Plate 86, figs. 2, 3; plate 100, fig. 7. 

 Quinqueloculina bicannata d'Orbigny, Ann. Sci. Nat., vol. 7, 1826, p. 302, No. 35. — 

 Terquem, Mem. Soo. g^ol. France, 8er. 3, vol. 1, 1878, pi. vii (xii), figs. lOa-c. 



In the Philippine material there is a very widely distributed 

 species which is characterized by two somewhat rounded carinae at 

 the outer border of each chamber. These are apparently identical 

 with the Q. hicarinata d'Orbigny, as figured b}^ Terquem. It forms 

 one of the characteristic species both in the Archipelago and south- 

 ward in shallow water. It is always short and broad, the central 

 part especially bicarinate, but the carinae often coalescing toward 

 either end. It is occasionally slightly striate, but it is not the same 

 as Q. cuvieriana. It was recorded at 41 stations in the area, ranging 

 in depth from 10 to 1,262 fathoms (18 to 2,309 meters), the average 

 depth 104 fathoms (191 meters). Bottom temperatures are given 

 for six stations, all of them in the deeper water. These range from 

 52.3° to 56.4 F. (11.2° to 13.5° C). 



The stations for this species range well over the Archipelago and 

 in the Sulu Sea, and to the southward in Darvel Bay, Borneo; Pitt 

 Passage; and Buton Strait.
