AVIFAUNA OF LAY8AN, ETC. 



and the Molokai ones kalaana. When first trying to diagnose my wikoni from Maui, I 

 compared it with stejnegeri of Kauai, not having true chloris before me, but C. chloris is no 

 doubt the nearest ally. Mr. Wilson's views about the distinctness of these forms are 

 apparently somewhat unsettled, but finally he accepted Mr. Perkins's view that they were all 

 distinct. However, these forms cannot be distinguished at all. Mr. Wilson's differences do 

 not exist in my series, nor in those collected by Perkins and now in the British Museum. 



Mr. Wilson (P. Z. S. 1890) is certainly Avrong in calling the underparts of C. chloris 

 "whitish buff, tinged with yellow." He repeats this statement on p. 2 of his article on 

 C. chloris, while on p. 1 he had described it correctly as " golden yellow." Also the state- 

 ment that " O. ehloridoides " has a " light lemon-yellow " underside " shading into buff on 

 the flanks " is not correct, the flanks being more olive than " buff." My Molokai specimens 

 are just as bright as those from Maui and Lanai. 



This is not the only instance in which islands of the central group are inhabited by the 



same form. 



Mr. Wilson tells us that all the specimens he shot on Lanai were observed in some fine 

 guavas, quite 30 feet in height. On Molokai he saw them searching for their insect-food 

 among the low shrubs of " ohia " which cover the sunny slopes of the ravines. 



I need not say that this species is named in honour of Mr. Scott B. Wilson, who was 

 one of the first who brought specimens of it to Europe, and to whom Hawaiian ornithology 

 owes so much of its recent progress.
