8. On a Skull of the Genus Kannemeyeria. 



(Text-figs. 12-14.) 



The genus Kannemeyeria was founded by Seeley in 1908 (Eep. 

 Brit. Ass., 1908, p. 713) on a skull of a large Anornodont found 

 by Dr. Kannemeyer near Burghersdorp, which is according to 

 Watson (Ann. Mag. Nat. Hist., 1912, x., p. 575) an imperfect skull 

 of Dicynodon simocephalus, Weithofer. Weithofer described his 

 species in 1888 (Ann. K.K. Natur. Hof Mus., Wien, Bd. iii.) and 

 figured the type, an imperfect skull. Broom (Bull. Amer. Mus., 

 1913) refers to this species as Kannemeyeria simocephalus. 



The genus is characterized by having a broad frontal region, a 

 narrow and high parietal crest, a parietal region inclined at an 

 oblique angle to the frontal plane, the pineal foramen at the front of 

 the parietal crest situated in a well-marked depression, an absence 

 of the postfrontal and probably of the preparietal bones. 



The hitherto described species are two : 



Kannemeyeria simocephalus (Weithofer), (loc. cit.], 



Kannemeyeria latifrons (Broom), 



and to these I now add a third, founded upon a well-preserved and 

 complete skull together with most of the lower jaw and the first 

 20 vertebrae found by Mr. E. W. Pocock at Winnaarsbaaken, 

 Burghersdorp, in 1914 (S.A.M. Cat. No. 3017), to which I propose 

 to give the name Kannemeyeria erithrea, sp. nov. 



Skull. The general shape of the skull can best be understood 

 from the figures. The orbits look almost entirely outwards. The 

 temporal fossae are large. The nostrils are near the front of the 

 skull. The snout is rugose as are the supraorbital borders and 

 the nasal overhang and is provided with a pronounced median 

 ridge which extends back to the plane of the front of the orbit. 

 From the posterior point to the plane of the back of the nostril this 

 ridge has a median groove, so that it has the appearance of being 

 double. 



The nostril is large, reniform in shape, and near the front of the 

 snout. It has a large, overhanging bony roof. The anterior border
