C. B. TICEHURST : DOWN-PLUMAGE. 191 



WREN Troglodytes parvulus K. L. Koch. 



Down. Colour. — Greyish black. 

 Character. — Scanty. 



Distribution. — Inner supra-orbital, occipital and spinal. 

 Coloration of Mouth. Inside, yellow ; no tongue spots ; 



externally, flanges lemon-yellow. 

 N.B. — Since this is the only species in which I have noted 

 the absence of the humeral tract, it is possible that it is 

 slightly developed but had become rubbed off in the 

 nest.

Distribution. — Inner supra-orbital, occipital, humeral, spinal,

externally, flanges very pale yellow.

humeral, spinal, ulnar, femoral and crural. 



N.B. — As I only had a spirit specimen to examine it is possible 



that the ventral tract, which in the Meadow-Pipit is only 



slightly developed, may have been overlooked.
