Mr. A. Smith Woodward/ though the head and fins, with the 

 exception of the caudal, are wanting. The vertebral column is 

 not fully ossified. The ribs are stout and reach nearly to the 

 ventral border, but their mode of attachment to the vertebral 

 column is not clear. The neural spines in a line with the 

 anterior edge of the anal are stout and clearly united with the 

 neural arches, which in their turn fuse with the centra. In 

 front of this point they are indistinct. The haemal arches and 

 spines are also well developed in the caudal region and broadly 

 expanded at their inner ends. There are no fulcral scales and 

 the rays of the caudal, which is the only fin preserved, are 

 jointed and finely branched. The rudimentary caudal rays 

 shown in Smith Woodward's figures of the Talbragar tish are 

 clearly visible in our specimen. The pelvic bones are laminar 

 and broadened at their inner ends. The posterior end of the 

 vertebral column is bent slightly upwards and there are no 

 hypurals such as occur in the Teleostea. The body was appar- 

 ently covered with very delicate cycloidal scales, the impression 

 of their internal faces being sculptured with extremely fine, 

 waved, concentric lines. No trace of the substance of the scales 

 is preserved, so they were probably not "ganoid." 



Length from anterior edge of origin of dorsal to posterior end 

 of vertebral column 40 mm. Breadth at origin of dorsal 25 mm. 

 Breadth of pedicel of tail 14 mm. 



Locality. — Casterton. From the railway cutting on the left 

 bank of the Glenelg. Found by Rev. J. H. MacFarlane, and 

 presented by him to the Ballarat School of Mines. 



The only other animal remains recorded from the mesozoic 

 area whence these fossils come is a Unio to which Sir F. McCoy 

 gave the manuscript name of U. dacoinbi. 



Sir F. McCoy records Taefiiopieris daifitreei ( Angiopieridium 

 spatJmlatuvi) from Murundal on the Wannon, and Mr. Dennant 

 mentions an Otozamites as having been identified for him by 

 Mr. R. Etheridge from tufaceous rocks at Mount Koroite.
