 no. 6, p. 11, 1910. 



Typical locality near Cape Lopez, western French Congo. 



Type probably in the Boston Museum, U.S.A. 



Larger than the preceding race, with the muzzle black ; 

 forehead mainly white, except for a triangular black area 

 between the ears ending in a point about three inches below 

 the line of the eyes ; skull -characters unknown. 



No specimen in collection. 



E. Potamoehcerus poreus congieus. 



Potamochcerus poreus congicus, Lonnberg, ArJciv Zool. vol. vii, 

 no. 6, p. 14, 1910. 



Typical locality Lower Congo. 



Type in Eoyal Swedish Museum of Natural History, 

 Stockholm. 



A provisional race, founded on the skull, which is much 

 larger than that of P. p. ulangensis, with the flat portion of 

 the parietal area narrow (31 5 mm.), and the facial tuber- 

 osities more developed than in any other race, the upper 

 ones projecting slightly above the nasal plane, and being 

 connected in old males by a bony arch on each side with 

 the lower pair ; nasal region wider than in P. p. pictus. 



Whether this type of skull is really distinct from that of 

 P. p. albifrons has still to be proved. 



No specimen in collection.

 1911 ; ScJioitteden, Rev. Zool. Africaine, vol. ii, p. 138, 1912. 



Typical locality Euwenzori district, Upper White Nile, 

 Uganda. 



Intermediate in general characters between P. chceropo- 

 tamiLS and P. poreus, and therefore suggestive that all the 

 forms of bush-pig are no more than local races of the Mala- 

 gasy P. larvatus. Schouteden considers this bush-pig to be
