The following series of new reptiles forms an important addition 

 to our knowledge of the Karroo faunas. The majority have 

 been found by the E.ev. J. H. Whaits, of Beaufort West. Of 

 the others one was found by Mr. Alfred Brown, of Aliwal Noi-th, 

 one by Mr. H. J. Hembury, and a few by myself. 



Suborder Dinocephalia. 



Taurops macrodon, gen. et sp. n. (PI. XC. fig. 1.) 



The snout of this large Dinocephalian was obtained at Bos- 

 manshoek at the foot of the Komsberg. Though so little has 

 been obtained we have enough to give the distinguishing characters 

 of this new type. In size it almost equals Tapinocephalus 

 atherstonei , but the snout though narrower is considerably deeper, 

 and it differs in the great degree of develojjment of the teeth, 

 especially of the incisors. Where the snout is broken across, 

 about the transverse plane of the back of the anterior nares, the 

 width is 190 mm. and the height about 100 mm. The anterior 

 nares are unusually small and situated about 90 mm. from the front 

 of the snout. The distance between the two nosti-ils is about 

 45 mm. The condition of the bone renders it almost impossible 

 to make out the sutures, the only one that is distinct being that 

 between the two premaxillaries.
