280 ORNITHOLOGY OF THE SCOTTISH NATIONAL ANTARCTIC EXPEDITION. 



The few species in the following list the identification of which I consider doubtful 

 are not numbered. 



I have to thank Mr W. P. Pycraft for having most obligingly examined certain 

 material submitted to him, and for giving me his valuable opinion thereon. 



I shall have occasion to make several references to the following works, in addition 

 to other literature :

 Captain DUGALD CAKMICHAKL, F.L.S. Trans. Linn. Soc., xii. pp. 483-513 (1817).

1. Nesospiza goughensis. 



Nesospiza goughensis Eagle Clarke, Bull. Brit. Orn. Club, xv. p. 18. 



This species possesses the essential characters of the genus Nesospiza as propounded 

 by Cabanis ( Journ. fur Orn., 1873, p. 154). It is a larger bird than the type (N. 

 acunkse) ; it has a longer and more slender bill, in which the culmen is more arched and 

 the keel of the mandible straighter ; and the third primary is slightly the longest. 



Adult Male. General colour bright olive-green, slightly washed with silvery grey ; 

 centre of abdomen, under tail-coverts, a stripe from the forehead over and behind the 

 eye, and a malar stripe olive-yellow ; chin, throat, and lores black ; primaries and 

 secondaries slate-grey, with silvery-grey tips and bright olive-green margins, and their 

 under surfaces broadly margined with silvery grey on the inner webs ; under wing- 

 coverts grey washed with yellowish green ; central pair of rectrices olive-green, the 

 rest grey edged and slightly washed with green. Bill and feet, in life, clove-brown. 

 Wing 4'15 inches, tail 3'68, tarsus T18, culmen 71. 



This is probably the summer plumage. 



Adult Female. Resembles the male, but is not so brightly coloured, being dull 

 green. Chin, throat, and lores dusky, and, with the buff stripes over the eye and on 

 the malar region, inconspicuous ; feathers of the back and outer margins of secondaries 

 slightly fringed with reddish brown ; secondaries and tertials tipped with greyish buff ; 

 flanks faintly washed with brown; middle of abdomen and under tail-coverts buff; 

 central rectrices dull green, the next edged with buff and the outermost with green. 

 Wing 4'0 inches, tail 3'5, tarsus 1'15, culmen '68. 



? Adult in Winter Plumage. Pileum and hind-neck olive-grey ; back tawny 

 olive, broadly striped with black on the interscapulary region ; upper surface, wing- 

 coverts, and tail washed with sage-green ; primaries narrowly edged outwardly with 

 brown ; secondaries broadly margined with sage-green and tawny olive ; under parts 

 greyish green, washed with tawny olive on the breast and flanks and "passing into buff 

 on the lower abdomen and tail-coverts.
