Cynidiognathus (?) broomi, n. sp. 
1911. Broom, Cynognathus berryi, Proc. Zool. Soc, pi. xlvi, figs. 1, 2. 
The occiput and outer view of the bones of the brain-case of an incomplete 
skull in the South African Museum collection (Cat. No. 1056) were figured 
by Broom as Cynognathus berryi. Eecent examination of the specimen has 
shown that it possesses 10 molars, and cannot therefore belong to the genus 
Cynognathus. In view of the general agreement between the two forms, 
as far as their features can be compared, I have tentatively placed it in the 
newly-erected genus. 
Comparison with Broom's figures shows that the division between the 
two condyles is not quite strong enough in the drawing he gave. Further, 
it seems doubtful whether the epipterygoid passed back to meet the quadrate 
as described by Broom. As actually preserved, the suture between the 
pro-otic and epipterygoid is rather more vertical below the big foramen than 
in his figure and the broken lower edge of the plate shows an interdigitation 
between the two bones. Unfortunately, the lower outer corner of the 
palate figured by Broom no longer appears on the specimen, so that it is 
impossible to settle the point definitely. 
No suture can be seen between the exoccipital and paroccipital ; the 
features of the region are mainly as in Watson's description of Diademodon. 
The post-temporal fossa is above the level of the foramen magnum. The 
fenestra ovalis lies lower than in Diademodon. 
The basisphenoid and basioccipital in ventral view are somewhat 
hollowed out, not flat, and in the posterior part there is a well-marked, 
narrow, shallow, median keel flanked by two narrow elongated grooves 
which pass forward well beyond the level of the tubera basisphenoidalia. 
There is a pronounced occipital boss on the upper border of the foramen 
magnum. 
The series of 10 molars occupy a length of 85 mm. The first is immedi- 
ately behind the canine. In Cynognathus and Lycochampsa there is diastema 
between the canine and the first molar, which is relatively largerin the latter. 
The frontal is more lozenge-shaped than in Cynognathus crateronotus, 
reaching to within 4 or 5 mm. of the orbital border. 
The probable length of the skull is 260-270 mm. ; the interorbital 
width is 52 mm., and the width at the canines 58 mm.

Broom has described all the visible features of the top of the weathered 
skull and of the postcranial skeleton. Since the type came into the posses-
