Fossil Fishes of the Upper Karroo Beds of South Africa. 269 



Besides the forms I have described, there are evidences of a 

 considerable number of others, but the remains are too unsatis- 

 factory for description. 



I must express my indebtedness to Mr. E. S. C. Dyke for taking 

 excellent photographs of the more important specimens.
