“ The Gambian j)ouched-rat is about double the size of the 
common rat (J/wa decumanus). In its colouring and proportions 
it greatly resembles that animal ; the fur is rather harsher 3 and 
more scanty ; the general colour of the upper parts of the body 
is a trifle paler than in M. decumamis. The head is tolerably 
long, and pointed; the ears of moderate size and rounded form; 
the feet are of moderate size; the tail is nearly equal to the head 
and body in length, thick at the base, covered with harsh, small, 
adpressed hairs, but these arc not sufliciently numerous to hide 
the scales; about one-third of the tail, at the base, is of a deep 
brown colour; the hairs covering the remaining portion are pure 
white; and the skin itself has evidently been of a paler hue than 
on the basal part of the tail. The fur on the body is somewhat 
adpressed, and the hairs are glossy on the back; they are of an 
ashy grey colour at the base; the apical half of each is brownish 
yellow, but at the points many of them are brownish; many 
longer hairs, intermixed with the ordinary fur of the back, are 
almost entirely of a brownish-black colour. The whole of the 
under parts of tlie head and body, and inner sides of the limbs, 
are white ; the hairs on the belly are rather scanty, and of an 
uniform colour, to the root ; the fore feet are whitish, and the 
tarsi are white, but clouded with brown in the middle. The 
ears are hut sparingly clothed with short hairs, which on the 
inner side are whitish, and on the outer brown. 
It lives in holes in the ground. At Fernando Po its flesh is
