MAMMALS OF BORNEO. ? 7 



MUS MARGARETT^. 



Mils uiargarctkti^ Thomas, Ann. Mag. N.H., Sec. 6, vol. xi., 

 May, 1893 (see frontispiece). 



Size, form, and general appearance very much as in 

 Vandclcnria olcracca. Whiskers numerous and prominent, 

 black. Ears small, oval, practically naked. Colour deep 

 rufous chestnut, mixed on the back with the gre}' of the bases 

 of the hairs, but clearing on the sides, where it seems to form a 

 rufous lateral band. Chin, chest, and belly white. Hands and 

 feet also white, but the metapodials with darker median patches. 

 Thumbs prominent, opposable, with a large nail ; claws of 

 fingers short and curved. Hallux also opposable, its claw 

 reduced to a minute conical point, not surpassing in length the 

 pad below it ; other toes all with their claws very short and 

 curved, and surpassed in length by the prominent terminal 

 pads. Soles naked, with six large rounded pads. Tail very 

 long, slender, finely haired, almost naked ; scales very small, 

 averaging about seventeen to the centimetie, their colour a sort 

 of pale greenish grey, the same above as below. Mamm:e, 

 I — 2=6. Palate-ridges, 3 — 5. 



Skull with a very peculiar and note-w^orthy resemblance to 

 that of Chii'opodoinvs^ agreeing with that of C/i. gliroides so 

 closely that it is not until a close examination is made that the 

 differences become apparent. General proportions short and 

 broad, the brain-case especially broad and rounded. 



Dimensions of the type obtained by Mr. A. Everett from 

 the Penrisen Hills, Sarawak — Head and body, 76 millim. ; tail, 

 144; hind foot, 197 ; ear, above head 11, from notch 13 ; 

 length of head, 28. 



This very remarkable species Mr. Thomas sa3'S will no 

 doubt need in the future the erection of a special genus or sub- 

 genus for its reception, and will perhaps prove to be congeneric 

 with Miis chh'opHS^ lately described by him in Ann. Mus. 

 Genov. (2), x., p. 884 (i8qi), and p. q^,^ (i8q2), pi. xi., figs. 4 — 7, 

 which also has the molar teeth of Mus combined with an 

 opposable hallux and a general C/u'ropodonivs — or Vandclcnria 

 — like form. In his description of this pretty little tree mouse 

 Mr. Thomas says, " I have taken the liberty of naming this 

 beautiful little species, which looks as if it would make a most 

 enchanting pet, in honour of Her Highness the Ranee of 

 Sarawak, a lady whose interest in the zoology of that country 

 is scarcely inferior to that of her husband the Rajah.
