Message: <blockquote data-quote="mb1848" data-source="post: 1691397" data-attributes="member: 31036">Ridgway in the title to the article where he described cryptoluecura did not sound too convinced it was really a new species.Description of a new Flycatcher and a supposed new Petrel from the Sandwich Islands.  A supposed new Petrel! He showed no queasiness in his description:“Hab.--Waimea Kaui, Sandwich Islands (V. Knudsen). (Types, Nos. 41949 and 41950, coll. U.S. Nat. Mus.)This fourth species of Cymocherea is very different from C. leucorrhoa (the only other having white on the tail coverts), in several very important particulars, as follows: (1) The upper tail-coverts are pure white terminated by a band of black .35-.50 of an inch wide; (2) the retrices (except the middle pair) are distinctly white at the base, though this white is concealed by the coverts; (3) the greater wing-coverts 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 Cymochorea, having very prominent nasal tubes, the outer toe longer than the middle, the tarsus about equal to the middle toe  (with claw), and the first primary shorter than the fourth as in a typical species of that genus. “<a href="http://www.biodiversitylibrary.org/item/53433#356" target="_blank">http://www.biodiversitylibrary.org/item/53433#356</a> .
