This variety differs from the type form in having an ovoid or sub-cylindrical 

 test. It is essentially a Tertiary species, and is frequent in the Neogene strata 

 of the Italian Sub-apennine area. There is little doubt that Brady's T. aspera 

 is referable to this variety, and it is Brady's species to which Howchin referred 

 the Muddy Creek specimens. Since the specific name, aspera, drops into 

 synonymy it relieves nomenclature of one preoccupied name, two other forms 

 having been similarly named by Ehrenberg and Terquem respectively *. 



Occurrence. — Grice's Creek, very rare ; Balcombe's Bay, very rare ; 

 Kackeraboite Creek, common ; Altona Bay Coal-Shaft, frequent. 



Textularia abbreviata, d^Orbigny. (Plate 3. fig. 55.) 



Textularia abbreviata, d'Orbigny, 1846, Foram. Foss. Vienne, p. 249, pi. 15. figs. 7-12 ; 

 Brady, Parker, & Jones, 1888, Trans. Zool. Soc. Lond., vol. xii. p. 219, pi. 42. figs. 4, 5. 



This short and broad form is a characteristic species in the Vienna and 

 Italian Tertiaries, and has been found living on the Abrolhos Bank off the 

 coast of S. America. Vine records it from the Port Phillip Tertiaries. Our 

 specimens are typical in outline, but the chambers are higher and fewer than 

 in d'Orbigny's original specimens. 



Occu7'rence. — Grrice's Creek, rare ; Balcombe's Bay, frequent ; Kackeraboite 

 Creek, rare. 



Textularia siphonifera, Brady. (Plate 3. fig. 56.) 



Textularia siphonifera, Brady, 1881, Quart. Journ. Micr. Sci. vol. xxi. p. 53 ; id., 1884, 

 Rep. Chall. vol. ix. p. 362, pi. 42. figs. 25-29. 



The localities which have yielded the above species in the recent condition 

 are almost exclusively those of coral-reef areas in the Pacific. It has also 

 occurred in the Grulf of Suez at a depth of 30 fathoms. At Funafuti it 

 occurred at various depths on the outer-reef slope of the atoll down to 

 150 fathoms, at which depth, at Funamanu, the writer found it to be most 

 abundant. 



Occurrence, — Grice's Creek, rare ; Balcombe^s Bay, very rare.
