" Large colony " is written on every label. 



No doubt this is the common field-rat of the country, and is 

 found on all soils and at any altitude. 



Some specimens are labelled native name "Ait," some " Tet," so 

 it is therefore probable that these names are simply the rendering 

 of our " Bat " and " Mouse.'' 



10. Dexdeomys lovati, sp. n. (Plate X.) 



The fur in its general appearance and texture resembles that of 

 Malacothrix typicus, but the ears are much shorter and the tail is 

 longer ; the whole upper surface longitudinally striped with black 

 and fawu. The tail is not so long as in any known species of 

 Dendromys, and is besides thickly covered with short adpressed 

 hair ; the fore and hind feet resemble those of Dendromys excepting 

 that the long fifth toes in the hind feet have no nails. 



The pattern of the markings are strikingly Tamias-like — abroad 

 black dorsal stripe, having a grizzled central line in its middle 

 portion, is flanked by two pale buff stripes, these again bordered 

 with black stripes. A dark stripe runs up the centre of the face 

 from the nose to the crown; darkish stripes also pass through the 

 eyes to the ears, leaving the sides of the forehead and cheeks buff'. 

 The part of the ear which naturally folds over in front has a black 

 spot as in Malacothrix ; the edges of the ears are rusty, and the 

 fur round them is also rusty buff. 



The whole of the underparts are dirty white ; the bases of the 

 fur in all parts of the body are dark slate-grey. 



The tail is two-coloured, rusty above and silvery whitish beneath ; 

 the fore and hind feet are thinly covered with very short pale 

 buff hairs. 



The fore feet have three long toes with claws, the first and 

 fifth toes being quite vestigial. The hind feet have three long 

 toes with claws; the outer or fifth toe is long, thumb-like, aud 

 partly opposable, but, so far as the single example shows, differs 

 from that of the known forms of Dndromys in being quite 

 destitute of a claw.
