7d MR. C. BODEN KLOSS ON 



Flower, and both appear to be examples of y. cincrcus stated by Mihie- 

 Edwards to extend from Siam to Cochiu-Cliina. The earliest form 

 described, X. coucaiuj (Boddaert), is said to have come from " Bengal", 

 (though from the name one would deduce a more south-eastern proven- 

 ance, as "konkang" is the -Malaj' name for the slosv lemur), but so 

 little is known of it that the subspecific distinctness from it of cinercu^, 

 now generally maintained, may eventuallj' be disproved. 



Wroughton (Journ. Bombay Nat. Hist. Soc, XXIll, p. 702) 

 has recently recorded a slow lemur from Mergui under Boddaert's name 

 and, though tiie locality is cjuite close to Koh Lak, there is apparently 

 a considerable difference in appearance between it and the more eastern 

 specimens. This lies principally in the warmer colour of the Tenas- 

 serim individual, in which also the dorsal stripe extends fi'om the base 

 of the tail to the crown where it splits and branches to the ears and 

 eyes. So far as I am aware, this last is a character of N. c. nudai/anus, 

 Anderson, of the Malay Peninsula, rather than of ^\ c. coucamj, in 

 which the face markings are said to Vje indistinct. It is verj' desirable 

 that further specimens from Indo-China .-hould be studied in order to 

 clear up the present uncertainty. 



The appearance and characters of the Koh Lak exam])le are as 

 follows: — head, nape and back between shoulders, fore-limbs ti'oni 

 below shoulders, greater part of iiiiitl-limbs, underside of bod3-, greyish- 

 white ; the hind limbs very siightlj- tinged with brownish. From the 

 crown to commencement of the rump extends a cinnamon-brown stripe, 

 broadest behind the shoulders where many liairs are black-tipped, 

 narrowest anteriorlj' where it is clearly defined and rather lighter in 

 colour, while posteriorly it is indistinct and gradually fades into the 

 colour of the rest of the body which is a sort of dull ochraceous-tawny, 

 for the most part strongly frosted with white. The eyes are surround- 

 ed by rings of mummy-brown, and the ears are tawny-ochraceous 

 situated in elongate patciies of tlie same coloui', but neither the eye 

 nor ear patches are in any way connected with each other or with the 

 dorsal stripe. The hairs of the pelage have grey bases throughout. 



On the skull the temporal ridges are separated by a sjiace of 

 about ■!■ mm. J)imensions : — greatest length, GO ; basal length, 

 oO ; zygomatic breadth, 41.7: width of braincase above zygomata,
