332 Mr. H. Druce on a neio Species o/'Papilio. 



General colour above dark broccoli-brown {Ridgioay\ this 

 colour runninG^ as usual on to the limbs, and extending on the 

 belly, as in //. orientalis, nearly or quite to the middle line, 

 the chin and throat, the axillae, and the inguinal region, 

 however, remaining orange or white. On the head the usual 

 white interorbital patch is reduced to two small spots, each 

 about one third of an inch square ; the postorbital marking 

 is a mere narrow line, sometimes almost obsolete ; while the 

 prominent nuchal line is reduced to a very narrow one, barely 

 reaching to the withers and more or less interrupted altogether 

 on the nape. Tail rather short, brown, its terminal half 

 mixed with longer whitish hairs, but less profusely so than 

 usual. 



Skull light and delicate, with a slender conical muzzle ; 

 zygomata diverging backwards, less boldly expanded ante- 

 riorly than usual. Infraorbital foramina of medium size. 



Teeth small, almost as small as in //. moschata, but of the 

 rounded shape characteristic of U. orientalis and its allies (see 

 measurements below). 



Dimensions of the type (a well-made skin, apparently a 

 male) : — 



Head and body 350 millim. ; tail 130 ; hind foot 46 ; 

 Jiairy part of sole 19. 



Skull : extreme length from gnathion to occiput 72 ; 

 greatest breadth 40*2; interorbital breadth 17'2; inter- 

 temporal breadth 15*7; breadth of brain-case 28'5; greatest 

 mastoid breadth 32 ; palate length from gnathion 33 ; palate 

 breadth between outer corners of Pii and — 18'4. 



Teeth : Eii, antero-posterior diameter 5*9, greatest oblique 

 diameter 6*0, distance from antero-external corner to back of 

 inner lobe 4*5 ; ??Li, greatest diameter 5"9; noTij length 6*0, 

 breadth 2-8. 



Ilab. Mount Kina Balu, N. Borneo, about 4000 feet. 



Type: B.M. 95.1.23.3. 



This species seems on the whole, as is natural, to be most 

 nearly allied to the Javan //. orientalis, Horsf., from which 

 it may be readily distinguished by its smaller size, smaller 

 teeth, and the reduction of the white head-markings.
