worth of recording as well as the great variabilitv of the skiills. 



In quite voung spécimens of P. p. ubaiigen.'sis the snout is 

 not vet whitish, but has the rufous colour of the bodv. The black 

 frontal patch is also not developed in the beginning, 



In the earliest stages (also represented in the Congo Museiun 

 the voung pigs of this race are verv beautifully striped longitudi- 

 nal! y in the sanie manner as I hâve described and figured ') 

 for a voung Potamocluvriis pig from Rutshuru, although still 

 more sharplv defined.

As far as is known to me, there has hitherto not been brought 

 to Europe anv spécimens of Bushpigs from the great Congo basin 

 between Congo and Kasai rivers, and to mv knowledge it has not 

 even been stated udiether the Bushpigs of this région belonged to 

 the /'orcz/^-group, although this was most probable, or not. 



There are, however, now in the Congo Muséum two skuUs of 

 Bushpigs which ha^ e been brought home bv D' Maes from the 

 district of Lake Leopold II. One of them is voung, but the other 

 is Qf an old boar with worn teeth. The latter has the pariétal 

 région verv broad compared with those of boars of P. p. uban- 

 gciisis. For comparison I hâve on the accompanying table ot 

 measurements recorded the cranial dimensions of this boar (Pot. 

 porcus albinuchalis n. ssp.), together with those of the oldest 

 and the largest of the skulls which I regard to belong to P. p. 

 nbdiigeiisis.
