ay DR. C. G. SELIGMANN AND MR. S. G. SHATTOCK ON THE 
August 11th, 1907.—Gloss on head limited; small uvegular 
areas of it on sides of face and neck; white ring faintly repre- 
sented at sides, absent in front and at back. The eclipse 
plumage is spreading rapidly upon the breast; this does not, 
however, present a typical appearance, although most of the 
feathers are brown with black centres, and the new ones coming 
through the down of the breast are of the eclipse type. There is 
no new flush upon the abdomen, though there are many brown 
feathers upon the flanks, where vermiculated feathers still 
prevail; it is not clear whether these brown feathers are new 
or not. In both wings the primaries, secondaries, and tertiaries 
are being rapidly moulted. Curly feathers are present in the 
tail. 
August 18th, 1907.—No flight-feathers remain in either wing. 
August 24th, 1907.—The eclipse on the body is not obviously 
proceeding. The curly feathers are still retained in the tail. 
September 1st, 1907.—There is still a good deal of gloss on the 
vertex and the nape; the white ring is slightly indicated at the 
sides of the neck, not at the back or front. The breast is in 
almost full eclipse; the change is certainly largely due to the 
appearance of new feathers, but in part seems to be due to pig- 
mentary change in the old. The feathers of the abdomen are, 
some eclipse, some vermiculated; there are feathers of both kinds, 
including a plentiful flush of young vermiculated feathers, on the 
flanks. ‘There are no curl feathers in the tail, though these were 
present five days ago. The two central feathers are dark and 
glossy, and are beginning to ridge; the other tail-feathers are 
glossy, as they always have been. 
September 12th, 1907.—The general aspect of the bird is inter- 
mediate; the majority of the breast-feathers that are fully 
grown are eclipse; there is, however, an abundant flush of young 
winter feathers coming through, although these do not yet affect 
the colour of the plumage. The vertex and the nape are glossy, 
but the cheeks present only a very few flecks of gloss; there is 
no trace of the white ring on the neck. Most of the feathers on 
the abdomen and posterior part of the breast are vermiculated ; 
practically these are all old, but among them there is an abundant 
flush of young vermiculated feathers coming through : the eclipse 
feathers are few in number. On the flanks the feathers are 
almost entirely vermiculated, but many of them are tipped with 
brown, including a number of old (eclipse) feathers ; new vermicu- 
lated feathers are coming through the down. The tail-coverts 
and back are glossy, with abundant new tail-coverts coming 
through. There are no curly feathers in the tail, but the central 
feathers are ridging and becoming glossy. 
September 21st, 1907.—The general appearance is that of a 
bird in winter plumage, with the exception of the head and 
breast, for the majority of the breast-feathers are of eclipse type, 
in spite of a flush of winter feathers coming through and a con- 
siderable number of winter feathers which have already expanded,
