OP NEW OR LITTLE KNOWN BIRDS. 331 



yond, 85. This species seems to vary considerably in the tint of 

 the upper plumage. Of three specimens now before us, one has 

 the head, breast, rump, and four middle tail feathers, entirely 

 purple ; another has these parts slightly tinged with green ; 

 while the third has the breast, rump, &c. entirely dark green : 

 in all other respects they are the same : the white freckles on 

 the wing and scapular covers are fine and delicate, and the tail 

 resembles that of T. ZeMCtfrws (probably the Surucuraof Azara). 



150. Trogon leucurus. 



Head and breast violet blue : back green : body^ be- 

 neathj crimson, without a white pectoral bar : lateral 

 tail feathers white, with their base black. Female cine- 

 reous : lower part of the body rose colour. 



Inhabits Southern Brazil. Mus. Nost. 



Total length 1 1 inches ; bill, gape 1 ; wings 5 ; tail, be- 

 yond, 3^. The wing covers of the male are very minutely 

 reticulated with blackiupon a grey ground ; the rump, and four 

 middle tail feathers, strongly tinged with blue : the extent of 

 the white on the outer portion of the lateral tail feathers varies, 

 but it is always pure and unhanded. In the female, the white 

 lines on the wing covers are very regular and distinct, andj'g 

 of an inch apart : the grey of the breast extends half way down 

 the body. 



151. Trogon lepturus. 



Outermost tail feathers attenuated and pointed ; the 

 three exterior pair banded and tipt wnth white : head, 

 neck, and breast, blackish : back, rump, and tail covers, 

 gilded green : body, beneath, yellow. — Female, fulvous 

 brown : body, beneath, pale yellow. 



Inhabits Cayenne. Mus. Nost. 



Total length of the female lOi inches; bill, gape 1| ; wings 

 4i ; tail, beyond, 4; ditto, base 6. Of this singular species, 

 remarkable for the attenuated form of the outer tail feather, 

 and even of the next to it, I have only seen the female, which 

 is probably that figured on PI. Enl. 736. ; although the ground 

 colour of the wing covers, in my specimen, is nearly of the 

 same brown as the back. The male is described in Sonnini's 

 Buffon, xvii. 330., from which work I have framed its specific 

 character in regard to colour ; and it is figured on PI. Enl. 

 195., where the narrowed form of the lateral tail feathers is 

 tolerably well preserved.
