Adult male. In general aspect and colour similar to the male of Chlorodrepanis chloris (Cab.), 

 from Oahu, but the breast and abdomen are equally tinged with olive- green, and the 

 throat and sides of the head are of the same tint. As a rule, the bill is larger than that 

 of C. chloris. It is easily distinguished from C. virens (Gm.) of Hawaii by the larger 

 bill, while the underside, although being less bright than in C. chloris, is more yellow. 

 Iris dark brown or hazel ; maxilla deep brown, with lighter base and edges ; mandible 

 brown, greyish towards the base. Wing 2*45 to 2*55 inches, tail 1*65 to 1'78, culmen 

 0*65 to 07, tarsus 0*8. 



Adult female. Above greyish olive-green ; below pale yellowish, washed with greyish olive 

 along the sides of the body, more yelloAv on the breast. "Wing-coverts with two rows of 

 light yellowish terminal spots. Smaller than the male; wing 2*2 to 2 4 inches. 



Immature males are like the females, but they become more yellow as they advance in age. 



Young birds have very conspicuous pale yellow cross-bars on the wings. 



The differences between the adult males of C. wilsoni and C. chloris are stated in the u key." 

 The females of C. chloris are more greyish above, those of C. loilsoni more greenish. 

 Young birds of the two species are sometimes hardly or not distinguishable. 



The types of C. loilsoni were shot by Palmer on the 14th July on Maui. 



I have now before me many specimens from Maui, Molokai, and Lanai. Mr. Wilson formerly 

 united the birds from these islands with C. chloris of Oahu, but now he has given names to 

 all of them, accepting my name wilsoni for the Maui form, calling the Lanai birds chloridoides,
