 is found on all the islands.

Although these birds are not rare I have only secured three. 

 They are so small and their color matches so well the green of the 

 foliage as to make it almost impossible to distinguish them. Their 

 faint little note, sounding like ss ss hissed in a subdued tone, 

 seems to come from almost anywhere and is a poor guide to their 

 location. They are found on the wooded mountain ridges and in 

 the caiions at an elevation of about iioo feet. An immature male 

 (No. 1335) was taken January 30 on Waiolani mountain at an ele- 

 vation of 1087 feet. This bird was busily engaged in looking for 

 small insects among the branches of a koa tree. Its stomach con- 

 tained five small larvae and the remains of two adult flies. On 

 February 21 I shot another (No. 1343) while feeding on small in- 

 secls which I saw it picking from the leaves and branches of an 

 ohia bush at an elevation of 1049 feet. This bird was accom- 

 panied by another which I thought to be its mate, for it soon re- 

 turned to the same bush and was taken (No. 1344). These two 

 specimens, a male and female, were in ver}' immature plumage 

 and their organs showed no signs of development ; so instead of 

 being mated they may have been merely members of the same brood. 



All of these specimens have the well curved horn- colored bill, 

 with light yellowish on the base of the lower mandible. The feet 

 and tarsus are dark with a raw umber tint. All have the greater 

 and middle wing-coverts tipped with whitish, surrounded with a 

 faint trace of olive green ; primaries and secondaries dark with 

 greenish edge to outer webs, which merges into light gray towards 

 the tips ; secondaries with more or less white on upper part of inner 

 web ; tail, dark with greenish outer edge to all the feathers except 

 the two outer feathers, which show a faint edging of grayish; 

 lores, grayish ; back, tinged with olive green. In No. 1335, evi- 

 dently an older bird, the coloring is brighter on the sides of head 

 above the ear-coverts ; there is also a bright yellow superciliary 

 stripe ; under parts, buffy white streaked with yellowish on throat 

 and breast; lower abdomen and under tail-coverts, white. Following 

 are the measurements of the three specimens: No. 1335.^ Length, 

 4.5; spread of wing, 7.75; wing, 2.56; culmen, .62; its depth at nos-
