and Sta Marta specimens than between the latter and the type of 

 T. fasciato-ventris, and quite as much resemblance between either 

 of the former and two examples of the Veraguan and Costa Rican 

 form (TJiryothorus melanogaster Sharpe, Cat. B. Br. Mus., vi, p. 

 230, pi. 14, fig. 2), in the National Museum collection (Nos. 61966, 

 9 ad., Bugaba, Veragua ; E. Arce, and 42808, $ ad., San Mateo, 

 Costa Rica ; J. Cooper), the two latter agreeing with the Panama 

 and Sta Marta specimens in having the whole breast uniform 

 blackish and the upper parts a rich rusty brown or chestnut, instead 

 of a much lighter and more fulvous brown. T. melanogaster may, 

 however, be distinguished by the pale rusty brownish instead of white 

 bars on the under tail coverts, and much less distinct (sometimes 

 quite obsolete) bars on the sides, flanks, and abdomen. There can 

 be no question, however, that this form grades directly into the 

 Panama form, which in all probability is only a local race of T. 

 fasciato-ventris. If this view of their relationship be correct, the 

 three would stand respectively as T. fasciato-ventris Lafr., T. fas- 

 ciato-ventris albigularis (Scl.), and T. fasciato-ventris melanogas- 

 ter (Sharpe).

It is very doubtful whether these are really the types of this spe- 

 cies, since they do not agree in all respects with the description. 

 Of one thing, however, there can be no doubt, viz., that they are 

 identical with T. brunneicollis Scl. ! Compared with four exam- 

 ples of the latter from southern Mexico, they are found to agree 

 in the minutest particulars as regards form, size, and coloration, 

 in which respects they are entirely unlike any South American 

 species of the genus. Not only are the under tail-coverts, but also 

 the entire flanks, barred with dusky and whitish (only the tips of 

 the flank-feathers being of the latter color, the basal portion being 

 pale fulvous or buffy) ; the middle wing-coverts have minute ter- 

 minal white spots ; the head a broad and conspicuous buffy super- 

 ciliary stripe sharply contrasted with the brown pileum and post- 

 ocular stripe, and the anterior and lateral lower parts are deep 

 tawny-buff, becoming much paler on the belly. Their measure- 

 ments are as follows : Total length (mounted specimens) 4.00- 

 4.20, wing 2.00-2.12, tail 1.70-1.80, exposed culmen .48, bill from 

 nostril .35, tarsus .75.
