66Q Mr. M. J. Nicoll on the Birds collected and 



inner half of the inner web (excluding the end) white. On 

 the fourth primary the white is extended on the outer web, 

 only in its preapical part, about 10 mm. long ; thus on the 

 extended wing taken as a whole it looks like a dark zigzag 

 band on a white ground. The ends of the primary-coverts 

 and remiges are ochreous in younger birds. Tail white, with 

 a narrow ochreous tip and a blackish brown apical band, the 

 ends of three central rectrices (or four in the younger bird) 

 being dark for a length of from 20 (on the outer pair) to 

 40 mm. (on the central pair). 



In the Ssredny-Kolymsk specimen, the youngest of all, 

 the three outer primaries are still quite undeveloped and the 

 tail-feathers are of equal length. 



In all the specimens the shafts of the rectrices are blackish 

 in the dark part, and white in the white part of the feathers. 



Old birds require no further description. I need only say 

 that even now, a year after they were Killed and skinned, 

 they (at least older males) cannot be described as having 

 the head and neck, with under-parts, rump, and tail white 

 suffused with pink, as the pink colouring is so intense, 

 though it has a somewhat salmon-coloured tinge' 56 '. The 

 bases of the pearly-grey feathers of the back and scapulars 

 are also roseate. The fat of this bird is nearly as orange 

 as that of Hamatopus ostralegus.

In the autumn of 1905 Lord Crawford once more most 

 kindly invited me to accompany him as naturalist during
