FISH-SCALES FKOM ECCA SHALES, NEAR LADYSMITH. 231 



Intombi Camp may therefore represent a hitherto unknown 

 species of Acrolepis, but it is desirable to await the discovery 

 of more satisfactory specimens before assigning to the fish a 

 specific name. 



It may be added that with these fish-scales were found 

 fragments of a Labyrinthodont jaw and a piece of fossilised 

 wood; and on the latter a report has been prepared by Mr. 

 E. A. Newell Arber.
