Rocky ilountaius, collected by the late Mr. J. K. Lord, have fallen 

 under my notice. They are all very much alike in the character of 

 their markings ; but one is much more saudv-coloured than the 

 others, the spots on the upper surface, and also the bands on the 

 tail being distinctly sandy buff instead of whitish ; all have six 

 bands on the tail, including the one at tlio tip. The throat-band, in 

 two out of the three birds, is blackish brown, with fulvous cross bars 

 on the feathers. The measurements are as follows : —

California. One specimen before me from this countrj- seems to 

 be a younger bird ; it is of a dark earthy brown, covered with little 

 oval .spots of sandy buff', the crown-spots rather more longitudinal 

 than those of the back ; the bars on the tail are sandy-coloured also ; 

 so that I suspect the tail-bands grow whiter with age. Underneath 

 the same dark tint prevails; the throat-band and sides of chest 

 earthy brown, mottled with spots and bars of sandy buff or fidvous 

 white ; the bands on the breast and flanks very broad and rather 

 rufous, not perceptibly narrowing towards the flanks. Another 

 specimen, though not adult, is rather older than the one above 

 mentioned ; the head is slightly barred, and the spots on the upper 

 plumage whitish, as also the bars on the tail. A third specimen 

 does not seem to differ from the British-Columbian birds, but is very 

 bleached. The three above-mentioned specimens have the follo\ving 

 measurements : —

At the same time I must observe that the birds considered to be 

 immature by me cannot be very young, judging from Mr. Kidgway's 

 description of the latter plumage. 



Mexico. Specimens from this country a;re the same as the iS^orth- 

 American ones, and I cannot see any difference at all. In three 

 specimens procured from Mr. Boucard, two have rather broader bands 

 on the breast, being probably younger birds. They measure as fol- 

 lows : —
