FORAMINIFERA AND OSTRACODA. — CHAPMAN. / 



Spiroloculina dorsata, Reuss, var. circularis, var. nov. 

 (Plate I., fig. 1.) 



Typical specimens of S. dorsata, Reuss^, are usually re- 

 stricted to shallow water. In the present variety, from deep 

 water, the distinguishing characters, due no doubt to the 

 difference in habitat, are the thin test, the prolonged apertural 

 neck, and the nearly circular outline. The largest specimen 

 has a diameter of .615mm., the smallest, .41mm. 



Station 36, east of Tasmania, 777 fathoms. Three 

 specimens. 



Spiroloculina grata, Terquem, var. reticosa, var. nov. 

 (Plate I., fig. 2.) 



This variety agrees with Terquem 's specific form^ in 

 general contour, having the same depressed type of shell ; 

 but the longitudinal and oblique ridges are perforated at 

 intervals in the interspaces. 



Length of figured test, 1.44mm. 



The species itself is common in coral seas of the Pacific, 

 both in shallow and deep water. 



Porty miles south of Cape Wiles, 100 fathoms. Two 

 examples. 



Genus Miliolina, Williamson. 



MiLiOLiNA AGGLUTiNANS, d'Orbigny, sp. 



This species is commonly found in shallow water, but 

 occasionally occurs at greater depths. M. agglutinans has 

 been recorded by the writer from shore-sand at Beaumaris, 

 Port Phillip. It is also known as a fossil in the Older Tertiary 

 (Balcombian) of Victoria. 



Forth miles south of Cape Wiles, 100 fathoms. One 

 moderate-sized specimen.
