32 HALKYARD, Fossil Foraminifera of the Blue Marl 



Very rare. A solitary specimen being found about the 

 middle of the Beds. This example differs somewhat from 

 d'Orbigny's figures inasmuch as the chambers have not the 

 same degree of backward curvature but are more horizontal, 

 however there is no doubt of its belonging to the species to 

 which I have assigned it. 



(The single specimen is somewhat more angular than in 

 d'Orbigny's figure and represents a passage form into 

 T. gramen.) 



56. Textularia concava (Karrer). 



Flecanium concavum, Karrer, 1868, Sitz. k. Ak. Wiss. Wien, 



vol. LVIII, Abth. 1, p. 129, pi. I, fig. 3. 

 Textularia concava, Brady, 1884, Chall. Rep-, p. 360, pi. XLII, 



figs. 13, 14; and pi. XLIII, fig. 11. 



Not rare, but almost absent from the upper beds of the 

 Marl, becoming more frequent in Gatherings 7, 8, and 9. The 

 specimens resemble Karrer's figures rather than those given 

 by Brady, being considerably depressed along the median line 

 and having the sutures and margins of the chambers limbate. 



57. Textularia globulosa, Ehrenberg. 



Textularia globulosa, Ehrenberg, 1838, Abbandl k. Ak. Wiss. 

 Berlin, p. 135, pi. IV, fig. B frequens. 



Frequent and generally distributed. 



58. Textularia folium, Parker & Jones.

pi. XVIII, fig. 19.

Rare, occurring only in Gatherings 8 and 9. The speci- 

 mens are small, and the species is evidently not in a habitat 

 favourable to its growth. 



(The main specimens though probably referable to T. 

 folium can hardly be described as satisfactory, but a typical 

 example occurs on one of the type slides. This appears 

 to be the first fossil record of the species, but we have 

 met with it (very rarely) in the Eocene of Spring 

 Creek, Moorabool River, Victoria, where the specimens are 

 curiously similar to those from Biarritz. The difference be- 

 tween these fossil specimens, and the recent type is more prob-
