cliin and throat indistiuctly streaked with dingy whitish and dusky, 

 while the jugukim and entire sides are dark slate, very much darker 

 than in the other specimens, only the centre of the abdomen being 

 whitish. Some of the feathers of the breast show indistinct whitish 

 shaft-streaks, while the entire under surface is pervaded by a greater 

 or less amount of fuliginous wash. The entire ui)per parts are a per- 

 fectly uniform black, the other specimens having a decidedly slate-col- 

 ored cast. The bill and feet of this specimen still retain their brilliant 

 hue, the entire mandible and edges of the maxilla being an intense 

 orange-red, while the legs and feet are a deej) orange-yellow color. The 

 collector's notes upou the label are as follows : " Iris white ; bill orange- 

 red, with upper mandible black ; tarsi and feet orange-yellow". 



This specimen was obtained at Cuscua, La Palma, September 25, 

 1881, by Mr. Juan Cooper. 



2, Thryothorus hyperythrus Salv. & Godm. (Biolog. Centr.-Am, Aves, i, p. 91). 



A single specimen from Carrillos, Alnjuela (October, 1879; Juan 

 Cooper), agrees exactly with examples from Veragua and Panama. 



3. Troglodytes (?) ochraceus, sp. nov. 



Sp. ch. — Above bright tawny-brown, duller posteriorly, the forehead 

 and lores more ochraceous ; a very conspicuous superciliary stripe of 

 bright ochraceous, most distinct posteriorly by reason of its strong 

 contrast with a broad post-ocular stripe of dusky brown. Entire side 

 of head (except as described), with whole lower parts, bright tawny- 

 ochraceous, paler, but by no means inclining to white, on the throat 

 and abdomen (the last deep buff). Eemiges and wing-coverts nar- 

 rowly barred or vermiculated with dusky, their inner webs uniformly 

 of this color; tail dull brown, narrowly and irregnlary barred, or ver- 

 miculated, with dusky. Crissum bright ochraceous-buff with a few 

 rather indistinct bars of dusky. Lining of wing plain pale ochraceous; 

 inner webs of remiges edged with grayish white. Wing, 1.80; tail, 

 1.25; culmen, .65; tarsus, .70; middle toe, .50. 3d, 4th, and 5th quills 

 equal and longest ; 2d equal to 7th ; 1st much shorter than the second- 

 aries (.60 shorter than longest primary). Tail graduated, lateral feather 

 .25 or .30 shorter than middle pair ; rectrices very narrow. Culmen 

 regularly and very decidedly curved from the base.

This diminutive and very pretty Wren is very diiferent both in 

 proportions and coloration from any other species with which I am 

 acquainted. In size it is about equal to Anorthura troglodytes^ but it is 

 otherwise not to be compared with that species, the bill being more 

 curved than in any other member of the group that I have seen (except, 

 perhaps, Z7ropsi7a leiicogastro, of which the only specimen of which, that 

 I have been able to examine, has the bill broken). It is with consider-
