 and fibulare.

SeyiHouria hayloriensis Broili. 



Right tibia, fibula, tarsus, and pes, reconstructed from my skeleton, 

 the cross-hatched phalanges are not preserved. 



The left foot retains a complete 2nd toe and a third which has 

 obviously been complete but from which part of the first and 

 the whole of the second phalange are missing, the piece of 

 matrix containing them not having been collected. These toes 

 have respectively 3 and 4 phalanges, the terminal one being in 

 each case a little conical bone. 



The foregoing description when read in connection with those 

 given by previous authors renders Seytnouria nearly as well 

 known as any reptile recent or fossil, and should allow of a very 

 thorough study of its taxonomic relationships and of the bearing 

 of its structure on morphological problems. Broili in his original 

 discussion recognised the extraordinary Stegocephalian appear- 

 ance of its skull. Williston, from a study of the whole skeleton, 

 concluded " That the relationships of Seymouria are not very 

 intimate with any other reptiles known from the Permian ; at
