Theriodonts. 85 



Specimen 4. — This is a small fragment of the skull of a 

 Cynognathus, not improbably belonging to the same individual as 

 the above jaws. It shows the posterior part of the right jugal and 

 squamosal l)ones and the articular region of the right mandible. 



Portions of the dentary, angular, })robably surangular, and 

 the greater part of the articular are well preserved. The specimen 

 shows the posterior arch of the jaw in almost perfect preservation.

Specimen ;">. — This is the type specimen of (xomphognathus 

 Kannemeyeri described and figured b}' Seeley (Phil. Trans, vol. 

 l.St) B., 18'J.">, p. 4). It consists of the back half of the skull, broken 

 off through the orbits, the entire mandibles, and the upper four 

 cervical vertebra^. The figure which Seeley gives of the side view 

 is inaccurate and misleading, owing, among other things to the 

 fact that the whole of the angular bone has been apparently inad- 

 vertently omitted from the drawing. 



The lower jaw, besides the almost perfect dentary, shows the 

 gretiter part of the articular, the whole of the outer side of the 

 aiigulai-, and the greater part of the flat bone which lies on the 

 inner side of the dentary near the point of union of the anterior 

 ])art of the coronoid pi'ocess with the ramus, and which I believe 

 U) bt' the surangular, but which is regarded by Seeley as the 

 '•ct)ronoid." The splenial is not displayed. 



The occiput is well displayed, and has been figured bj' me 

 (Proc. /jot)l. Soc, 1903, vol. 1). The sutures unfortunately cannot 

 be made out with certainty. The specimen also shows the squa- 

 mosals, jugals, and postorbitals (postfrontals) very satisfactorily, 

 and in a less satisfactory condition the })arietals and part of the 

 frontals. The sphenoidal and articular regions are fairly well 

 displayed. 



The spi-cimeu shows most l)eautifu]ly (he structui-e of the 

 upper four cervical vertebrae including the proallas. These have
