latter as H. chloridoides, and that from the former as II. kalaana. It then appeared 



to me that some ornithologists would consider the differences too slight to be accounted 



specific, and I accordingly refrained from doing more than indicating their existence. 



I have since found that Mr. Perkins, who obtained a good series of examples of each, 



has in his manuscript lists kept them apart (though I am not aware of his having 



published his views on the subject), and I therefore consider it advisable to follow his 



example, without pledging myself to the opinion that they are more than local forms. 



I here repeat the characters which I then thought would serve to distinguish them : — 



Oahu. — A trace only of a yellow mark from the bill to the eye. Upper parts 



of a dark greyish buff tinged with a faint shade of olive. Underparts whitish buff 



tinged with yellow. Bill and legs dark brown. — True H. chloris. 



Lanai. — A distinct yellow mark from the base of the bill to the eye. Upper parts 

 light greyish buff, distinctly tinged with olive. Beneath on the breast and throat 

 light lemon-yellow, shading into buff on the flanks. Bill and legs lighter brown. 

 The bill is more slender. — H. chloridoides. 



On the island of Lanai all the specimens which I obtained were shot in some fine 

 guavas, quite 30 feet in height, which fringed the edge of the streamlet of the deeply- 

 wooded Waiapaa ravine. The birds were so busily engaged in hunting for insects, 

 which abounded in the guavas, that I had an excellent opportunity of observing their 

 graceful movements ; here I saw the old birds feeding the young with small flies, larvae, 

 and other insects. 



Molokai.— A distinct yellow mark from the bill to the eye, as in the Lanai form. 

 Upper parts darker than in the Lanai form, but not so dark as in the type from 

 Oahu. Underparts yellow, but not so bright as in the Lanai form. Bill and legs 

 considerably stouter than in the preceding form. — //. kalaana. 



On Molokai I have often with delight watched this bird searching for its insect-food 

 among the low shrubs of ohia which cover the sunny slopes of the ravines on that 

 island, in my opinion the most lovely of the group, visited, however, but seldom by 

 travellers, on account of the Leper settlement being situated on its shores.
