latter is a very interesting animal, since, as its name indicates, it 

 serves to connect the south-eastern P. choeropotamus with the western 

 P. porcus. 



The face below the eyes and the muzzle are white, with the 

 sensory bristles and a narrow cheek-band above them black. A broad 

 blackish band, blending superiorly into a brownish patch towards the 

 otherwise whitish crown of the head, extends across the forehead 

 between the eyes. The black ears have whitish margins near the tips 

 and some white hairs in the terminal tufts. In the dorsal crest the black 

 bristles have long whitish tips which communicate the dominant colour 

 to the whole. The back and flanks are pale rufous, with a few black 

 bristles ; but, with the exception of the whitish chin, the under-parts 

 and limbs are black. The whole coat is long and bristly, as in 

 P. choeropotamus, and affinity with that type is indicated by the strong 

 development and mixed colour of the dorsal crest. On the other hand, 

 the general colour and colour -pattern are of the P. porcus type, 

 especially as represented by the white-snouted P. p. ubangensis. 



THE FOREST-HOG 



(Page 396) 



In the Proceedings of the Biological Society of Washington for 

 1910, vol. xxiii. p. 49, Mr. G. M. Allen shows that in colour and 

 general character the West African forest-hog is identical with the typical 

 Hylochoerus meinertzhageni. The Washington specimen shows no very 

 definite warts on the face with the exception of one below each ear ; 

 but this is doubtless a feature peculiar to the female. The forest-hog 

 of the Ituri is also regarded by. Mr. Allen as not more than a race of 

 the same animal. It is added that the term " giant pig," sometimes 

 applied to these black swine, is a misnomer, for in reality they are not 

 particularly large, although standing high. In the Florentine journal, 

 Pubblicazioni del R. Istituto di Studiisuperiori, Sezione di Scienze Fisichc 

 e Naturali for 1909, Dr. E. Balducci describes a forest-hog from the 

 upper Congo as a new species under the name of H. gigliolii. This, 

 however, is probably inseparable from the Ituri H. m. ituriensis (supra, 

 p. 398) with which the author of the paper appears to have been 

 unacquainted. 



The forest-hog figured on p. 397 of the text was shot by Captain 

 W. R. H. Dunn.
