41 Differing but slightly from typical C. chloris and Mr. Wilson's proposed Lanai species C. chloridoides. Seledled specimens from a short 

 series of spring birds (May to June) show the following fairly constant differences. Males: Under parts of *a/aa7?a more olive and golden 

 than in cklortdoides, -which in turn is less lemon yellow than in typical chloris; color of feet and beak similar ; Aa/aawa duller olive yellow 

 above than chloris, which is duller than chloridoides which is decidedly yellowish olive on the rump ; lores of kalaana blackest, chloridoides 

 "next, while chloris is decidedly greyish sooty ; super-loral stripe most extensive in kalaana, brightest in chloris, and least contrasted with the 

 adjacent parts in chloridoides. With the females kalaana is lightest olive grey above, quite light over the upper mantle and differing from 

 chloris, which is deeper, and from chloridoides in being less olive grey ; rump and tail coverts of kalaana grey with but slight olive cast ; chloris 

 is tawny olive, while chloridoides is olive green ; lores of kalaa7ia smoky grey, not differing from chloris, but lighter than chloridoides where 

 t hey are sooty ; super-loral stripes in kalaana yellower and more noticeable than in chloris, and less so than in chloridoides which is quite a de- 

 cided yellow ; below, kalaana greyish olive white with yellow wash ; chloris with more grey and less yellow ; chloridoides yellowish olive. 

 Hence, male kalaana has the under parts more olive and golden, duller olive yellow above ; lores blackest; super-loral stripe more extended; 

 otherwise similar to r/i/oW.s. Female: Lighter olive grey above, quite light over the mantle; rump similar to upper mantle; lores smoky 

 grey; super-loral stripe more noticeable than in chloris ; below, greyish olive washed with yellow ; differing least from chloris. Both kalaana 

 and chloridoides seem to be species of only sub-specific value.
