upon the crown ; the tail markings quite different, having the 

 black subterminal band conspicuously less broad/' Now this 

 is in no way applicable to our present species, which, taking 

 the relative sizes of the two into consideration, has quite as 

 fully a developed crest, quite as much black on the crown, and 

 very nearly, if not quite as bi*oad, a subterminal tail band. 

 This species cannot possibly therefore be S. spilogaster, and 

 must stand under Jerdon's name. S. albidus, Cuvier, which has 

 been suggested as applicable to this species, pretty clearly 

 applies to the northern form, S. cheelu. — Hume, " Nests and

Immature specimens of this species are most commonly 

 obtained in India ; the following are dimensions and description

Male. — Length, 33*8 ; expanse, 86*25 ; wing, 24*8 ; tail from 

 vent, 12*5; tarsus, 352 ; bill from gape, 2'6. 



Female. — Length, 34*0 ; expanse, 88-0 ; wing, 26'0 ; tail from 

 vent, 13'0 ; tarsus, 4'2 ; bill from gape, 3"05. 



The fourth primary is the longest ; the third is sub-equal ; 

 the second is 1*4 shorter ; the first 4*5, and the fifth, 0"6 shorter. 

 Exterior tail feathers — male, 1'4, female 2'2, shorter than the 

 central ones.

 portion of the cere yellowish brown ; bill blackish horny ; 

 the head, nape, cheeks, ear-coverts and sides of the neck hair

 basal half, in some for fully the basal two-thirds, but very 

 little of the white showing through, the feathers being densely 

 set ; all the feathers of these parts long and linear, those of the 

 occiput especially ; the back of the neck, the whole of the

 domen a warm buffy fawn colour, changing to white at their 

 bases, and more or less broadly tipped with hair brown ; the 

 longer scapulars and the upper tail-coverts, which latter are very
