48 HAWAIIAN BIRDS. 



leaves a minute space at the lower margin open ; the second prim- 

 ary is about one-tenth of an inch shorter than the third ; the third, 

 fourth, and fifth are nearly equal, but the fourth is a trifle longer. 

 The coloration is that of Chlorodrepanis virens. The bird thus 

 occupies a somewhat intermediate position between Oreomyza and 

 Chlorodrepanis, and it might be a hybrid between Oromyza mana 

 and Chlorodrepanis virens; but, as Oreomyza parva of Kauai oc- 

 cupies a similarly intermediate position between the genera Ore- 

 omyza and Chlorodrepanis, I think it is quite possible that it is a 

 good species, and I have much pleasure in naming it after Mr. 

 Perkins, who has done such very good work on the Hawaiian 

 Islands in furthering our knowledge of their biology." 



"Adult male. Above light olive-green (Ridgway, Nom. Col- 

 ours, pi. X., No. i8). brighter on the rump. Quills black, edged 

 with oil-green; tail-feathers dark brown, edged with oil-green. 

 Below olive-yellow; vent greenish white. Thighs dirty white. 

 Under wing-coverts white, with a yellow tinge ; lores black. Iris 

 dark brown. Legs and feet greyish brown. Soles of feet yel- 

 lowish flesh-colour. Upper mandible dark brown, with paler 

 base; lower mandible grey. Total length about 5.5 inches, wing 

 2.6, tail 1.7, tarsus 0.85, culmen 0.63. 



One male, Puulehua, [Kona] Hawaii, September 25, 1891. 



Resting as it does upon a single specimen, the status of this 

 recently described species can hardly be considered as settled until 

 after further investigation. Its description indicates that it is 

 very closely related to the Chlorodrepanis virens; or, as suggested 

 by Mr. Rothschild, it may be a hybrid. 



Oreomyza bairdi Stejneger. Akikiki. 



This is the Kauai representative of the genus. It is a larger, 

 more robust bird than the one just mentioned and is differently 

 colored, but in general habits the two species appear to resemble 

 each other closely. 



Description. — Adult. Above hair brown, tinged with pale green on rdmp 

 and on margins of wing and tail feathers. Below olive-buflf, nearly white 

 on chin and throat, and tinged with pale yellow on the breast and abdo- 

 men. Lores whitish. Length about 4.45.
