1889.] MAMMALS OP KINA BALTJ. 231 



prominently white-rimmed ears, the dark patches behind the latter, 

 and in its less bushy tail. It is also woithy of note that although 

 S. tenuis, throughout its range, is singularly uniform in coloration, 

 yet, if anything, the Bonieaa specimens of it are darker in 

 colour, and are therefore still less like S. jentinki than are those 

 from the Malay Peninsula, a fact which shows that the two species 

 have no tendency to grade into one another. 



I have named this species in honour of my friend Dr. F. A. 

 Jentink, Director of the Leyden Museum, to whose labours we are 

 indebted for much of our knowledge of the mammals inhabiting the 

 East-Indian Archipelago. 



Mr. "Whitehead informs rae that 8. jentinki ranges on Mount 

 Kiua Balu from about 3000 to 8000 feet altitude.

This common species, the Plantain Squirrel of Pennant, is repre- 

 sented by two specimens of the blue-bellied type, without any trace 

 of red or yellow on their undersides. 



At the cost of another change of name, I am ;;lad to be able now 

 to supersede the barbarous term " S. hadjiny" which I was guilty 

 of resuscitating on account of its priority over the commonly used 

 " S. plantani." An examination of Boddaert's rare work proves, 

 however, that the Plantain Squirrel had already received a Latin name 

 there, and one also that is fortunately both classical and appropriate.

Native name " Mantok." 



Size very small, only slightly larger than that of S. exilis, Miill. 

 Ears narrow, pointed, their tips provided with beautiful black and 

 white pencils of hair, so long as to reach, when laid backwards, 

 almost to the withers ; the ears themselves edged with black, and 

 with a marked white spot on the head behind them. Colour other- 

 wise uniformly finely grizzled olive-grey all over, exactly as in 

 jS. exilis and S. concinnus. Claws both before and behind long, 

 very sharp and much curved, so as to enable the animal to hang on 

 to almost, or quite, vertical surfaces. Palms with five large pads. 

 Soles with four subequal digital pads, and a small circular posterior 

 pad ; back of sole hairy for about 9 or 10 milHm. 



Skull very peculiarly shaped, with a short and broad cranial, and 

 a disproportionally long and powerful facial portion, the distance 

 from the tip of the nasals to a point between the anterior edges of 

 the orbits 12'8 millim., as compared to 11 "3 in S. exilis, and 11
