HAWAIIAN BIRDS. 39 



much resembles in habits. It seems to inhabit the whole forest 

 region of Kauai." 



Description. — Adult. Head above olive, feathers edged with olive-green, 

 giving a spotted appearance; back, edges of wing and tail quills and of 

 wing coverts bright olive-green ; wing and tail quills ashy brown ; a bright 

 yellow superciliary line, and a black loral spot. Throat and breast deep 

 olive-yellow, merging into sulphur-yellow on abdomen; tibiae dull white. 

 Length about 7.50 inches. 



Adult female. Above greyish olive; rump and upper tail-coverts olive 

 green ; a dusky loral spot below olive-yellow ; sides and flanks olive-green. 



Hemignathus lanaiensis Rothschild. 



Several specimens of this species v/ere obtained on Lanai in 

 1892 by Mr. Rothschild's collectors, but it is doubtful if the 

 species is still in existence, as it was then very rare. 



Description. Adult male. Differs from H. obscurus, its nearest ally, 

 in its much longer and very stout bill, ashy-greyish tint of the crown, and 

 much duller olivaceus green of the back, neck, and rump. Breast dirty 

 yellow, gradually passing into dull olive on the flanks, instead of bright 

 yellowish olive as in H. obscurus. Under tail-coverts creamy white, in- 

 stead of olive-green. (Rothsch.) 



Hemignathus ellisianus (Gray). 



This form of the akialoa used to inhabit the forests of Oahu 

 where Mr. Wilson thinks it may still linger in small numbers. No 

 collector, however, has seen the bird for many years and its ex- 

 istence is open to much doubt. The single specimen in the Berlin 

 Museum is supposed to be the only specimen extant. 



Description. — Above greenish olive-brown, more greenish on the back 

 and rump and more greyish on the head and hind-neck; the dark bases 

 of the feathers on the head showing through. Lores deep brown. A dis- 

 tinct yellow superciliary stripe. Chin, throat, and middle of abdomen dull 

 brownish white (apparently somewhat faded). Upper breast olive-green- 

 ish; sides of breast and flanks dull olive-greenish. More olive-brown on 

 the flanks. Wings and tail deep brown, bordered with yellowish green. 

 Under wing-coverts dull white. The bill is brown, somewhat horn-brown, 

 but not blackish as in all the other species of Hemignathus. (Rothsch.).
