FROM THE KARROO BEDS OF SOUTH AFRICA.

bone is present or not the evidence does not show. There is 

 certainly no preparietal boss such as occurs in the species of 

 Eocy clops. 



The orbits look almost directly upwards. 

 The postorbital arches are long and well developed. 

 The squamosals must have been extremely broad, judging from 

 the portions preserved. 



The following are the principal measurements of the type : — 

 Greatest antero-posterior length... about 460 mm. 



Greatest width ,, 420 „ 



Distance between tusks 80 ,, 



Interorbital width ICO ,, 



Intertemporal width 45 ,, 



Basal length about 410 ,, 



I have much pleasure in naming this new type after Prof. H. F. 

 Osborn.

Top of parietal region of skull of Dicynodon watsoni Broom. 



The degree to which the postorbitals overlap the parietals is unknown, ])ut most 



probably it is not greater than is indicated in the figure. 



DiCYNODON WATSONI, sp. n. (Text-fig. 32.) 



This new species is founded on a very fragmentary skull, of 

 which little more than the frontal and parietal regions are \)yq- 

 served, found on the mountain to the east of New Bethesda, 

 about 800 feet above the horizon of the village and probably in 

 the Lystrosaurus zone. It is a near ally of D. oshorni though 

 quite a distinct species, and important in giving details of the 

 structure of the preparietal region.
