TERTIARY FORAMINIFERA OF VICTORIA. 27 



Textularia rugosa, Reuss sp. (Plate 3. fig. 57.) 



Tlecanium rugosum, Keuss, 1869, Sitzuiigsb. d. K. Ak. Wiss. Wien, vol. lix. Abtli. i. p. 453, 

 pi. 1. figs. 3 a, h. 



Textularia rugosa^ Eeuss sp., Brady, 1884, Eep. Chall. vol. ix. p. 363, pi. 42. figs. 23, 24 ; 

 Howchin, 1889, Trans. E. Soc. S. Australia, vol. xii. p. 7. 



This species has also been found at Muddy Creek (Lower Beds). The 

 short varieties bear some resemblance to T. gramen, but may be distinguished 

 by the strongly excavated sutures o£ the chambers. 



Occurrence. — Grrice^s Creek, very rare. 



Genus Spiroplecta, Ehrenberg. 



Spiroplecta sagittula, Defrance sp. (Plate 3. figs. 58, 59.) 



Textularia sagittula, Defrance, 1824, Diet. Sci. Nat. vol. xxxii. p. 177 ; 1828, vol. liii. 



p. 344, Atlas Couch, pi. 13. fig. 5 ; Howcliiu, 1889, Trans. R. Soc. S. Australia, vol. xii. p. 7. 

 Spiroplecta sagittula, Defr. sp., Wright, 1891, Proc. R. Irish Acad. p. 471 ; id., 1902, 



Irish Naturalist, p. 211, pi. 3. 



The above species was first shown by J. Wright to belong to the genus 

 Spiroplecta on account of the spiral arrangement of the initial series of 

 chambers. 



S. sagittula has been recorded by Howchin from Muddy Creek (both Lower 

 and Upper Beds), and by Vine and Watts from the Port Phillip Tertiaries. 



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

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



Spiroplecta sagittula, Defrance sp., var. fistulosa, Brady. (Plate 3. 

 fig. 60.) 



Textularia sagittula, Defrance, var. fistulosa, Brady, 1884, Rep. Ohall. vol. ix. p. 362, 

 pi. 42. figs. 19-22 ; Howchin, 1889, Trans. R. Soc. S. Australia, vol. xii. p. 7. 



Li the Lower Bed at Muddy Creek this variety seems to be comparatively 

 rare. It is, however, nearly as common as the specific form in the present 

 series. Brady regarded the fistulosity as a redundant growth peculiar to 

 examples occurring in tropical or sub-tropical areas. 



Occurrence. — Grice's Creek, common ; Balcombe^s Bay, common ; Altona 

 Bay Coal-Shaft, frequent. 



Spiroplecta carinata, d'OrUgny sp. (Plate 3. fig. 61.) 



Textularia carinata, d'Orhigny, 1826, Ann. Sci. Nat. p. 263, No. 13 ; id., 1846, Foram. 

 Foss. Vienne, p. 247, pi. 14. figs. 32-34. 



T. carinata, d'Orb., var. maorica [var. antipodum in text], Stache, 1864, Novara,-Exped., 

 Geol. Theil, vol. i. p. 271, pi. 24. figs. 21 a-c.

Although this species is common at one of our localities it is rare to find a
