1. On some Fishes from the Lower and Middle Karroo Beds. By 



E. BROOM, M.D., D.Sc. 



WITH the exception of a couple of species of Atherstonia, described 

 by Smith Woodward, almost nothing has been known of the fishes 

 of the Lower and Middle Karroo. The fishes of the Burghersdorp 

 beds and of the Cave sandstone have been dealt with by Smith 

 Woodward and by myself, and a good many forms are now known. 

 The fishes of the older rocks, though less varied than those of the 

 upper, are nevertheless interesting. The types of the following 

 specimens are in the collection of the South African Museum. 



PAL^ONISCIDAE. 



PAL^ONISCUS CAPENSIS, sp. nov. 



This new species is founded on three specimens from the Hantam 

 Mountains, 12 miles west of Calvinia, and from beds which are 

 probably Upper Dwyka, and thus of Lower Permian age. The 

 specimens unfortunately are all of the posterior part of the fishes- 

 one shows almost all except the head, but the other two only the 

 tail halves. The preservation of the specimens is marvellously 

 perfect. 



The total length of the specimen was probably 300 mm., and the 

 greatest depth of the body about 75 mm.
