 urhital region, a mon- jn-ar-shainvl luainease, a shallower rostrum and 

 a relatively narrower maii(iil)le. 



The principal differences lietween the two forms lies in tlie uluij"' 

 of the teeth, which in the Nej.,'ri Semhilan aninial are very l»rojid and 

 square, aj^reeinij with those of the tyi«' of C. u HIum - and differin^j not-

 sluqje of the teeth, are the features on which the sii1»j,'»'niis in en-t-ttil,
