theii" root there is a quantity of stiff hairs which extend over and 

 })artly conceal them. 



The tail is shorter than one half of the head and body together, 

 scaly, and covered with numerous hairs, which spread in all direc- 

 tions, so as in no manner to conceal the scales. Immediately 

 before the anal aperture, rather in its anterior, somewhat labiate 

 margin, there is, in both sexes, a small pore leading to a minute 

 bag or cavity, secreting an offensive matter. This glandular organ 

 I do not find recorded in the family, although it occurs in all the 

 other Pig- rats of these parts. 



The clitoris is not furnished with a furrow, but forms an en- 

 tirely closed tube having an opening at its apex*. I have only 

 found three pair of paps, each surrounded by a little naked 

 area, the hindermost between the thighs, about equidistant from 

 tlie sexual organs and the navel ; the two other pairs are situ- 

 ated rather on the sides of the body than below the belly ; one 

 of the pairs before the navel, the other distant about 40 milli- 

 metres from it. 



The skin is remarkably brittle and loose in texture. 



The colour of the upper part of the body is yellow-brown, 

 much shaded with black. All the hairs and spines are here 

 Ijluish gray at the base, becoming gradually darker towards the 

 a j)ex ; or they are marked with a broad, rust-coloured zone below 

 tlie black apex; but in such proportion that, while by far the 

 majority of the spines want this bright zone, the reverse obtains 

 in regard to the hairs. On the sides of the body, downwards, 

 the ferruginous yellow prevails, while the spines diminish in 

 number, and the black colour tends more and more to the 

 grayish, until it entirely disappears on the belly. Here the hairs 

 are of one uniform colour their whole length ; along the sides of 

 the belly there is a band of yellow-red ; the middle is pure 

 white, and the portion so marked, which widens both before, 

 towards the chest, and behind, towards the groins, is sharply 

 defined from the above-mentioned enclosing band, and without 

 the slightest transition of colour. The bands unite between the 

 fore-legs, excluding entirely all white colour on the breast ; the 

 lower part of the neck and throat is reddish, though this colour 

 becomes fainter anteriorly. On the outside the limbs have the 

 same colour as the sides of the body, becoming fainter towards 

 the feet, where there is a greater admixture of white hairs ; the 

 long bristles which extend over the claws are white. The inner 

 part of the extremities is almost naked, especially of the hind- 



* This peculiar structure belongs to all the other forms of the family 

 which I have been able to examine, but has not hitherto been noticed, as 

 far as I know.
