Eudiastus (E. lingulatus, Amegh.), described by Amegbino, 

 from the Santa Cruz beds in Patagonia, are not yet sufficient!)' 

 characterised. 



FAMILY CERCOPITHECID^ (Vol. I., p. 248). 

 GENUS PAPIO <^supra, p. 253). 

 Several species of this still living genus have been recovered 

 from strata of the Tertiary epoch : Papio sub-himalayanus 

 (Meyer), from the Sivalik hills, of Lower Pliocene age; P. 

 FALCONERi (Lydckkcr), from the Pleistocene bone-caves of 

 Madras, India, and in the superficial deposits of Algeria, 

 North Africa ; and P. atlanticus (Thomas). 



The Sivalik species was closely related to the existing 

 North-African Baboons.

 The characters which distinguish this genus are the in- 

 cisors, which are chisel-shaped above and scoop-shaped below ; 

 the large upper and lower canine teeth ; the upper pre-molars, 

 which approach in shape to the molars, with the outer cusps 

 higher than the inner, and the inner one strong; the upper molars 

 with two pairs of opposite conical cusps, separated by a longi- 

 tudinal furrow, and with a strong cingulum ; the posterior 

 upper molar smaller than the median ; the lower molars smaller 

 than the upper, with two pairs of cusps, and a fifth on their 

 hind border, which in the hindmost tooth is developed into 

 a strong talon. The face is short, and the chin rounded. 

 Oreopithecus bambolii, Gervais, is the best known species, and 

 was obtained from the Mid-Miocene lignites of Monte Bamboli,
