other material for verifying this statement than Major's fi- 

 gures, but as these in other instances are quite correct, I 

 have 110 doubt that they are in this case, too. The distance 

 from the postorbital process to crista lamhdoidea is in Major's 

 figure of P. kassarna not less than about 31 7o of the upper 

 mesial length of the skull, and this is a very remarkable 

 difference from P. choeropotamiis in which this percentage ap- 

 pears to vary from usually about 26 to a t most 28%. 

 An other characteristic by which the Abyssinian Bush Pig dif- 

 fers from the P. choeropoiafnus-growp and shows resemblance 

 to the western P. porcus-group is also mentioned by Major 

 and quite plainly seen on his figures. It consists in the shape 

 of the apophyses above the canines which are stout but low. 

 The general shape of the skull when seen from the side with 

 its proportions of length and height reminds also more about 

 P. porens than about P. choeropotamiis. It appears thus 

 to be right to consider P. hussarna (Heuglin) as a separate 

 species, which in some respects resembles its western and in 

 others its southern relatives. With regard to these mixed 

 characters it offers an analogy to the following species:

A male Bush Pig in British Museum Nat. Hist. (7. 12. 

 18. 1.) collected by R. J. Cunnustghame 20/2 1907 at the »Vic- 

 torian Nile, Uganda, altitude 4,000 feet» is a very remar- 

 kable specimen as it forms an intermediate link between the 

 Western P. porcus-grouip and the Southern — Eastern P. 

 choeropotamus- gr on-p uniting certain characteristics from both, 

 as the following description proves. The whole face and 

 snout in front of the eyes is white only with the sparsely 

 scattered sensory bristles black. A narrow black cheek band 

 is found above the not strongly developed bristles. Between 

 the eyes across the forehead there is a broad blackish band 

 shading out posteriorly in a brownish triangulär patch to- 

 wards the otherwise whitish crown of the head. The ears 

 are black but with a whitish upper margin of the most dis- 

 tal part, and with some of the hairs in the tuft white. The 

 dorsal crest is strongly developed with long whitish tips to 

 the long black bristles. The light tips produce the domina- 

 ting colour. The whole back ofj the animal and the sides
