the feathers next to the middle ones shaded with ashy ; head chest- 

 nut-brown, varied with paler tips to the feathers, producing a some- 

 what spotted appearance ; lores dull white, mottled with dusky

 which separates it from the crown ; ear-coverts dull white, streaked 

 with black, with which colour the feathers are edged ; cheeks white, 

 streaked with a few blackish edgings to the feathers ; under surface 

 of body white, the abdomen and flanks tinged with buff, the whole

 confused and rather blotched, those on the breast and abdomen 

 pear-shaped and very distinct, smaller on the abdomen ; under tail- 

 coverts white, with large black spots ; thighs brown, mottled with 

 dusky bases to the feathers ; under wing-coverts and axillaries 

 white, spotted with black ; quills ashy brown below, with large

 7'1 inches, culmen 1, wing 3'25, tail 3-2, tarsus 1-15.

Winter jdtimage. Not different in any particular degTce from the 

 summer plumage, beyond the fact that both sexes are perhaps a 

 little lighter coloured and have the spots on the under surface a 

 little smaller. 



jS'tstling male. Distinguished from the adult birds by the blackish 

 head. The general style of plumage is the same, but it is rather 

 more reddish and is more spotted, the back, instead of being streaked, 

 having triangular white spots on the feathers, which are also barred 

 with dusky blackish. The under surface of the body is like the 

 adult, but the blotchings on the throat and chest are broken up, so 

 that these parts appear more spotted. 



JS^v^tlhvj female. Similar to the nestling male, but a little more 

 reddish brown above, the head clearer brown than in the foregoing. 



Xantus's Cactus-Wren is confined to Lower California.
