6 " ENDEAVOUR " SCIENTIFIC RESULTS. 



BILOCULINA ELONGATA, d'Orbigny. 



This species in temperate seas frequents shallow water, and 

 deepens its habitat in more tropical areas. It has been 

 recorded fossil from the Victorian Balcombian Series, and 

 where found may indicate that deposit to be of moderately 

 deep-water origin, since the climatic condition was wanner 

 than at present. 



Station 36, east of Tasmania, 777 fathoms. One specimen. 



BILOCULINA IRREGULARIS, d'Orbigny. 



B. irregularis is a fairly deep-water species, and is generally 

 distributed in the Southern Hemisphere. It has, however, 

 been recorded from the North Atlantic, off Palma, Canary 

 Islands. 



Station 36, east of Tasmania, 777 fathoms. Frequent. Of 

 variable size. 



Forty miles south of Cape Wiles, 100 fathoms. Common. 



BILOCULINA LUCERNULA, Schwager. 



Station 36, east of Tasmania, 777 fathoms. Common. 

 Specimens small, but otherwise typical. 



BILOCULINA SARSI, Schlumberger. 



Biloculina sarsi, Schlumberger, Mem. Soc. Zool. France, 

 iv., 1891, p. 553, pi. ix., figs. 55-59 ; woodcuts, 10-12. 

 Chapman, Jour. Linn. Soc., Zool., 1907, xxx., p. 14, 

 pi. i., figs. 1, 2. 



This species has been dredged from the North Sea and 

 from around the Subantarctic Islands of New Zealand. As 

 a fossil it occurs in the Balcombian Series of Port Phillip. 



Forty miles south of Cape Wiles, 100 fathoms. One 

 specimen.

 specimen. 



SPIROLOCULINA CANALICULATA, d'Orbigny.
