24, 
the time we left, (nearly 1 p. m.) I feel confident that the whole 
colony must have assembled. 
Other smaller colonies were subsequently visited, but not one 
single egg rewarded our perseverance. ‘The Faqeers assured 
me, * that the young birds were from 2 to 3 months before they 
were able to leave the nest. 
The following are the dimensions of this es Length, 37 
to 40.—Expanse, 88 to 92. Wing, 23°50 to 22'5; the 3rd and 
4th, or 4th primaries are the longest; the lst is from 2°5 to 
235 shorter, and the 2nd 0°5 ‘to 1 shorter. Tail, of 14 
feathers, from 10 to 11; the longest tail feathers exceeding 
the shortest, by from 0°5 to 2. ‘Tarsus, from 3°5 to 4. 
Foot, greatest length, 7°75 to 85; ereatest width, 6°5 to 7 ; 
mid toe, 3°75 to 4:2, its claw, along curve, 1: 15 to 1:45; 
hind toe, 1°25 to 1:6, its claw, along curve, 1:25 to 1°75; 
inner toe, 1°55 to 1°9, its claw, along curve, 1:25 to 1°75. 
Bill, straight, from edge of cere to poit, 1°68 to 1°8; 
along curve, 2 to 2:25; from gape, 2°6 to 2°85; width 
at gape, 1:12 to 1:32; height at margin of cere, 0°8 to 
0°92; length of cere, 0°9 to 1°12. 
Lower tail coverts reach to within 3 of end of tail. The 
legs and feetare dusky cinereous. ‘I'he irides are brown. ‘The 
weight varies from 11 to 14 Ibs. 
In the perfect adult, brownish white hair-like feathers are 
thinly sprinkled over the head, nape, cheeks, and throat. 
The upper half of the back and sides of the neck, and whole of 
the front of the neck are excessively thinly studded with small 
star-like tufts of dewn. The lower half of the back, and sides, 
of the neck are perfectly bare. The crop patch is closely 
covered with silky, tight fitting, dark hair brown feathers. 
The whole of the rest of the lower surface is a pale whity 
brown, becoming almost a pure white towards the vent and 
lower tail coverts. The ruff is full, soft and pure white, of 
very downy feathers, the webs much disintegrated. The whole 
mantle is pale earthy brown, the centres of the lesser, and all 
but the tips and margins of the larger scapulars, being dark, 
hair brown. 
The lower back, rump and upper tail coverts white, tinged 
with pale earthy brown, many of the feathers, however, espe- 
cially of the longer tail coverts, being brown at the base, but 
so broadly tipped and margined with the paler colour, that little 
of the brown shows. The primaries and tail feathers are deep 
chocolate brown. ‘The secondaries and tertiaries hair brown, 
more or less suffused, on their outer webs, with pale, dingy 
earthy or fulyous brown.
