(No. 34,238, 9-) Top of head, back, and scapulars steel blue, with a 

 ereenish gloss, more violet in some specimens. Forehead from the eyes (not 

 strictly defined), nuchal bands and rump (but not tail coverts), dark chestnut 

 brown ; chin, throat, sides of breast and crissum, especially near anus, lighter 

 chestnut brown ; the sides of body and inside of wings smoky brown, tinged 

 with the color just mentioned ; median region of the body white. No blackish 

 on the breast or on forehead. Wings and tail with their upjDer coverts lustrous 

 brown. A dusky spot in the loral region. 



(No. 34,238, 9.) Total length, 5.00; wing, 4.20; tail, 2.10; perjiendicular 

 depth of fork, .15 ; diflference between 1st and 9th quills, 2.00 ; length of bill

The feathers of the back have a white patch ou each side the shaft, 

 about the middle, causing white streaks when visible among the 

 feathers. The forehead and rump are quite dark chestnut; the 

 chin and throat, with crissum just behind anus, come next in shade, 

 this color fading still more on jugulum and sides (the jugulum some- 

 times darker than chin), and scarcely appreciable posteriorly on the 

 side of the abdomen. The longer feathers of crissum are dark brown, 

 with reddish-white edges, much paler than near the vent. The white 

 of the belly is sometimes glossed faintly with chestnut, especially 

 along the shafts of the feathers. The axillars and lining of wings, 

 with tibia, are of a smoky gray, with a rufous tinge. The chestnut 

 nape is narrow, and sometimes quite obsolete ; the color of the neck 

 behind it is dull and lustreless. The dark chestnut of the rump 

 extends round on the sides as well as above, continuous with the 

 paler tinge of the anterior portion of the crissum. The inner web 

 of the lateral tail feather is edged with whitish near the end. 



There is no black band along base of upper mandible, as in Iiini- 

 frons. The chestnut feathers of the front exhibit a tendency to 

 dusky centres, except near the bill, a feature not noticed in other 

 species. 



This bird is much smaller than the North American Zu»(/>o?is, 

 and differs in the rufous chestnut (not whitish) front, the absence 

 of black patch on throat, much lighter rufous of the throat (paler
