78 THE RUFOUS-THROATED HILL PARTRIDGE. 



universally want* the black line (so strongly marked in the 

 Himalayan birds) dividing the rufous at the base of the throat 

 from the grey of the breast. 



I shall, therefore, give the dimensions of the two races 

 separately : — 



Himalayan Birds (nine specimens measured) : — 



Males. — Length, io'O to iro; expanse, i6*o to 17*5 ; wing 

 5 # i2 to 5*37 ; tail from vent, to to 2*25 ; tarsus, ro to 1*55 ; 

 bill from gape, 0*87 to 0*93 ; weight, 7 to 10*5 ozs. 



Females. — Length, 9*0 to 10*5; expanse, 1 55 to 17*0; wing, 

 4-9 to 5*2 ; tail from vent, 20 to 2*2 ; tarsus, 1-35 to 1*45 ; bill 

 from gape, 0*82 to 0*90 ; weight, 7 to 10 ozs. 



Legs and feet red, at times intense red ; bill black ; irides 

 brown ; orbital skin and gape fleshy pink to bright red. 



Tenasserim Birds (twenty-five specimens measured) : — 



Males. — Length, 1075 to 11*25; expanse, 18*4 to 19*5; tail 

 from vent, 2*25 to 275 ; wing, 5*65 to &o ; tarsus, 1'6 to i*8 ; 

 bill from gape, C95 to ri ; weight, io*o to 12*0 ozs. 



Females. — Length, icro to 10*5 ; expanse, 1&6 to 18*5 ; tail 

 from vent, 2'0 to 2*3 ; wing, 5-3 to 5*6 ; tarsus, 1*52 to 175 ; 

 bill from gape, 0*9 to ro ; weight, 8'o to io*o ozs. 



Legs and feet pale pinky red ; bill horny black ; irides deep 

 brown ; orbital skin bright red. 



All these measurements, &c, were recorded from freshly 

 killed birds. There appears to be no difference in the plumage 

 of the two sexes in either race. 



The PLATE is fairly satisfactory, but the legs and feet of the 

 birds in the foreground are not sufficiently red for Himalayan 

 birds. The bird peering through the grass represents the Ten- 

 asserim race, wanting the black throat line. 



* In this respect agreeing with the Aracan Hill Partridge (A. intermedins), which, 

 indeed, it closely resembles ; but the Aracan bird is decidedly smaller, has one nearly 

 unbroken black patch covering more or less of the throat (instead of a number 

 of small round black spots), and is, on the breast and generally, rather paler 

 coloured. The Tenasserim form is quite as distinct as that from Aracan. Those 

 who consider it specifically distinct must call it A. ticke/li, after its discoverer. 

 I personally should be inclined to suppress intermedins.
