50 Allen — The West African Forest Pig. 



black bristles which reach a length of 50 mm. at the apex; the posterior 

 surface has a very few scattered tine black bristles, bnt is otherwise prac- 

 tically bare. Tlie body is covered with coarse black bristles which are 

 longest on tlie neck and the dorsal ridge. The longest neck hairs meas- 

 ured 1(34 mm., those on the middle area of the ])ack, 132 mm. The fore 

 and hind legs are furnished with shorter bristles, from 10 to 20 mm. long. 

 On the ventral surface of the body, scattered among the sparse black 

 bristles are others of a pale cinnamon color or " yellowish white." Simi- 

 lar light-colored hairs are present on the inner side of the fore legs and 

 thighs, and on the anterior edge and proximal two-thirds of the inner por- 

 tion of the ears. At the corner of the moutli on each side is a patch of 

 these light bristles for a length of about 65 mm., and a conspicuous tuft of 

 the same along the posterior angle of the mandil)le, (>xtending vertically 

 some 45 mm., with a width of about 10 mm. Tlie hoofs are smooth and 

 blackish. 



The skin is dark gray and rough, but there are no very definite warts on 

 the face, except that below the ear, along the posterior angle of the 

 mandible, is a thickened crescentic area on which grows the tuft of light 

 bristles, in much the same position as a similar tuft in the ^Vart Hog 

 {Phacochoerus}. The tail is laterally compressed and l)ears a few small 

 scattered black hairs, except along its dorsal and ventral edges, which 

 for their terminal 55 nnn. have a stiff crest of close-set black bristles the 

 longest of which, at the tip of the tail, attain a length of some 30 mm. 



Measurements of the skin. — The skin, preserved in brine, when straight- 

 ened out, was found to measure approximately 1,500 mm. in total length, 

 of which the tail is about 250 nnn. The following additional measure- 

 ments were made: Greatest transverse diameter of snout irhinarium), 

 105 mm. ; greatest vertical diameter, 57 ; distance between nasal apertures, 

 42; ear from meatus, 119; greatest breadth of ear, 91 ; median lengtli of 

 hoof of fore foot, 41; of dew claw, 41.5; median length of hoof of hind 

 foot, 39; of dew claw, 35. 



Skull. — The skull appears to l)e that of a nearly full-grown animal, 

 doubtless a female, and is even smaller than the type specimen as indi- 

 cated by the measurements. Tlie last molars are just erupted and unworn. 

 They are not so narrowed jiosteriorly as those figured by Thomas, but are 

 bluntly rounded. I'ollowing are the measurements of this skull, with the 

 (M)rresponding dimensions of the type in parentheses: Median occi]iito- 

 nasal length, 325 mm.; basal length, 279 (325zb); ))alatal k'Ugtli, 1!«) 

 (232); greatest lengtli of nasals, 1S2 (191 ); greatest width of combined 

 nasals posteriorly, 4S (42) ; greatest width between postorbital processes, 

 10(5; least interorbital width, 78 (88); least width between orl)it and 

 canines, 53; widtii at vertex, 90; orbit to tip of nasals, 213; height of 

 muzzle in front of premolars, (>5 (57); least breadtli of maxillary zygo- 

 matic processes below orbit, 39 (42); least vertical breadth of zygomata 

 behind true orbit, 34.5 (36); palatal width between posterior ends of ni\ 

 52; mandible from condyle to tip of i', 277; depth of jaw at diastema, 

 42; width across sockets of canines, 97 (98): breadth between tijis of 

 canines, 163 (181); greatest diaineter of canines, 25 (24); upper molar
