Mr, G. N. Lawrence on the Genus Gymnoglaux. 185 



newtoni, and which has been considered of late to be G. nu- 

 dipes, Daud,, I find them strikingly unlike, differing in ap- 

 pearance even more than the latter does from the Cuban 

 species. Consequently the name G. neivtoni must be restored 

 for the bird from St. Croix and St. Thomas. 



There being, in my opinion, three well-marked species of 

 the genus Gymnoglaux, and having specimens of each, I think 

 it may be of interest to have their characteristics defined.

 Male. Upper plumage clear dark rufous, with a few small 



obscure pale markings on the upper part of the back ; the 

 scapulars are crossed with whitish bars, which are tinged 

 with rufous and edged with black ; front of a lighter rufous, 

 crossed with waving lines of brown ; lores and superciliaries 

 of a pale rufous white ; ruff" dark brown at the bases of the 

 feathers, their ends white ; middle tail-feathers and outer 

 webs of the others rufous brown, mottled with nearly obso- 

 lete darker markings ; the outer webs of the outer feathers 

 have a few irregular bars of pale rufous, the inner webs are 

 dark brown ; middle and larger wing-coverts blackish brown, 

 ending with rufous, and having subterminal white spots on 

 their outer webs ; the quills on their outer webs are dull 

 rufous brown, indented with white spots, the inner webs are 

 dark hair-brown ; the under plumage is whitish, closely 

 marked on each feather with shaft-stripes of dark brown, and 

 crossed on both webs with narrow waving lines of paler rufous 

 brown ; thighs and feathers of the tarsi for half their length 

 light rufous, distinctly barred with blackish brown ; bill

Male? The plumage above (of my specimen from St. 

 Thomas) is of a dull rufous, with narrow, irregular, rather 

 indistinct markings of brown, and broader ones of pale rufous.
