1076 Dll. R. BROOM OX NEW PERMIAX 



Taogxathus megalodox, gen. et sp. n. (PI. LXTI. figs. 2-4.) 



This new genus and species is founded on an imperfect and 

 much crushed snout found by myself on the farm Kuilspoort, 

 Beaufort West distiict. Though little more than tlie orbital 

 i-eo-ion is preserved, this specimen is manifestly very unlike any 

 type previously known. 



The frontal region is flat and moderate'y broad, the interorbital 

 measurement being 16 mm. The orbit measures about 20 mm. 

 in length. 



The greater part of the dentaries is preserved but the anterior 

 part of the beak is missing. The jaw differs from that of all 

 previously known Anomodonts in the much longer portion covered 

 by horn, and also in that the anterior part of the lower yiw 

 instead of being narrower than deep, is here about twice as broad 



as deep. 



The teeth are remarkable in that while there is a tusk it 

 was pi-obably relatively short, and in the lower jaw there are two 

 large teeth each about half the size of the tusk. N"ot im- 

 probably there were two molars in the maxillary and two in the 

 mandible. 



The nearest ally of Taognathus at present known is Prodicynodov, 

 but the affinity is not at all close. 



OUDEXODOX BOLORHIXUS, Sp. n. (PI. LXIII. fig. 10.) 



This new species of Oudenodnn, was discovered by myself at 

 Kuilspoort, Beaufort West district. Unfortunately, the type 

 consists of only the preorbital portion of the skull, and this is 

 somewhat crushed and weathered. 



The most striking characteristics of the species are (1) the 

 extreme shortness of the snout which brings the front of the 

 palate nearly under the orbit, and (2) the thickening of the nasal 

 bones to form a rounded boss which overhangs the nostrils. 



The orbit is large and measures about 35 mm. in diameter. 

 The borders are thickened and rounded. 



The maxillary bone is short but powerful ; the caniniform 

 process being very massive. The upper part of the bone forms 

 part of the thickened lower margin of the orbit and nearly 

 separates the jngal from the lachrymal. 



The premaxilla.iy bone is also short and strong, and was 

 probably as represented in the restoration. 



The nasals are short but greatly thickened, forming a large 

 median boss the sides of which overhang the nostrils. 



The frontal bones are short and comparatively narrow, the 

 intei'orbital region measuring about 36 mm. 



The onlv species of Oudenodon which seems to come near the 

 present one is Othdenodon sb'igiceps Owen, but this latter difters, 

 apart from difl^erences that may be due to crushing, in the much 

 greater size of the nostril and in the much more backward position 

 of the caniniform process.
