molars. The dental formula of Alo2Jecopsis atavus is thus the 

 very remarkable one : — i. f, c. J-, m. ■§- = -j-. As will be seen from 

 the figure I give, the clentary is very peculiarly shaped. Behind 

 the canine the upper border of the bone is deeply concave, so 

 that, even if there had been teeth, they could not have met molars 

 in the upper jaw unless they were exceptionally long. The back 

 part of the dientary is powerful, and there is a long but thick 

 coronoid process. The coronoid bone is well developed, not so 

 deep as and much thicker than the coronoid in Gorgonopsians 

 or Cynodonts. The back part of the jaw is not sufficiently Avell 

 preserved to admit of description, but it is relatively much shorter 

 than in Gorgonopsians and apparently more like that of Bauria. 



MOSCHORHINUS KITCHIXGI, gen. et sp. nov. 



This new genus and species is founded on a well-preserved 

 specimen discovered by Mr. James Kitching near New Bethesda 

 Road. It consists of the anterior two-thirds of the skull of 



Text-fio-ure 7.

a moderately large Therocephalian. The specimen is slightly 

 crushed, but the matrix is only slightly harder than the bone, 

 and it has been found possible to display almost every detail 

 of the structure of the palate. 



The skull is manifestly that of a broad-headed short-snouted 

 form, the front of the snout being usually blunt and wide. 



The premaxillaries are broad and powerful, and each carried 

 six well- developed incisors. As preserved, each bone has onlv 

 five teeth, but quite manifejstly the 3rd is lost from the right 

 side and the 6th from the left. The Avhole series measures 41 mm. 

 The first four incisors are much flattened and with the loiiff axis
