Genus — Sagrixa, cTOrh%(jny. 



115. ■^>S'. limbata, Br. PL i., fig. 7. A single specimen of this 

 very rare form was obtained from the Lower Bed. The test is. 

 longer and more slender than Mr. Brady's figure, and is also 

 more curved in outline, but in all essential features agrees per- 

 fectly with the type. The specimens on which the species was 

 determined by Mr. Brady came from Torres Straits, and this is 

 only one of the many illustrations of the identity of forms be- 

 tween the last-named locality and the Lower Tertiaries of Southern 

 Australia, 



FAMILY GLOBIGERINID/E. 



Genus — Globigerixa, cVOrbiyny. 



116. G. bnlJoides, d'Orb. Lower Bed, very common. Upper 

 Bed, rare. 



117. *G. hnlloides var. triloba, Rss. Lower Bed, rather scarce^ 



118. *0. iirfJata, d'Orb. Lower Bed, rather scarce. 



119. *G. Jie/icina, d'Orb. Lower Bed, rare. 



Genus — Orbulina, cVOrbigny. 



120. 0. universa, d'Orb. Lower Bed, very common, frequently 

 large. Upper Bed, rather scarce. 



Genus — Spiiceroidixa, cVOrbiyny. 



121. **S'. buUoides, d'Orb. Lower Bed, examples small but 

 moderately common. 



FAMILY ROTALIDyE. 



Genus — Spirillixa, Ehrenhery. 



122. *>S'. decorata, Br. Differs from the recent form in possess- 

 ing a rounded edge instead of being carinate, and in the absence 

 of transverse furrows. Lower Bed, rare. 



123. >S'. tubercidata,^Y. Mr. Brady's figures show the convolu- 

 tions as visible on the exterior surface, wholly or in part, but the 

 Tertiary examples have a greater tubercular growth ^^'hicll com- 

 pletely hides the septal lines, and often renders the shell slightly 

 biconvex. Lower Bed, rather scarce. Upper Bed, very rare. 



124. *S. limbata, ^Y. Lower Bed. Specimens small and some- 

 what rare. 



125. *>S'. incnpialis, Br. The convolutions of the superior face 

 are strongly marked by raised, limljate ridges, with the depressed 

 areas coarsely pitted. The inferior side of the shell is of greater 

 extent than the superior, perfectly flat, shows no septal lines ex- 

 teriorly, and is uniformly covered with tuljercles. Lower Bed^ 

 rather scarce.
