Eah. — Waiinea Kaui, Sandwicli Islands {Y. Knudsen). (Types, Nos. 

 41949 and 41950, coll. U. S. J^at. Mus.) 



This fourth species of Cymochorea is very different from C. leucorrhoa 

 (the only other having white on the tail -coverts), in several very im- 

 portant particulars, as follows: (1) The upper tail-coverts are pure 

 white, terminated by a baud of black .35-.o0 of an inch wide; (2) the 

 rectrices (excejjt the middle pair) are distinctly white at the base, 

 though this white is concealed by the coverts ; (3) the greater wing- 

 «overts and outer webs of the tertials are much darker, offering less 

 decided contrast with the general color of the wings; (4) the tail is 

 much less deeply forked, the depth of the fork not exceeding .30 of an 

 inch, whereas in C. leucorrhoa it amounts to about .75 of an inch. In 

 other respects the two species are much alike. 



This bird is a true Ci/mochorea, having very prominent nasal tubes, 

 the outer toe longer than the middle, the tarsus about equal to the mid- 

 dle toe (with claw), and the first primary shorter than the fourth as in 

 the tyi)ical species of that genus.
