Specimen (5. Consists of a series of 10 dorso-lumbar vertebrae 

 of the same individual as the skull (spec. 5). The j-ibs resemble 

 very closely those of Cynognathus crateronotus, but have the 

 broad flattened ribs relatively shorter. The vertel)rae are probably 

 the 10 immediately in front of the sacrum.

TRIRACHODON KANNBMEYERI, Seeley. 



Specimen 7. This is the type specimen of Trirachodon Kan- 

 nemeyeri described and figui-ed by Seeley (Phil. Trans., vol. ISGB, 

 1895). It is an almost perfect skull with the jaws in position, and 

 with the remains of the atlas and axis vertebrae. All the sutures 

 on the external surface of the skull are very distinct, but the 

 occiput is much crushed and impeifectly displayed. Both den- 

 taries are almost perfect, and on the inner side of the right is seen 

 a part of the delicate splenial. Both articulars and angulars are 

 also well shown. The quadrates are very small and svi})ported by 

 downward processes of the squamosal. From the inner corner of 

 this downward process there passes inwards a very delicate bony 

 bar. This is manifestly the homologue of the bone in Cynog- 

 nathus, which I believe to be the tympanic. 



The axis, atlas, and proatlas I have figured and descril)ed else- 

 where (Proc. Zool. Soc. 1903, vol. 1). 



Pres. by Dr. R. Kannemeyer. Near Burghersdorp). 



Specimen 8. The greater part of a skull with the lower jaws 

 attached. The snout has been broken off in front of the canints, 

 and the back part broken off through the parietal and sphenoidal 

 regions. Though this specimen difl'ers very greatly from the type 

 I have no hesitation in referring if to the same species — the 

 differences being due to the fact that the type is immature and 

 crushed, and this specimen m.ature and uncrushed.
