terially, except in having the spots less distinct bent^ffii ; the white strsalts 

 less c«ii.spiuuous above; the white of the vings soil-j.' with rufous. Speci- 

 nieiH vary considerably in the proportional as well4|P^ absolute thickness 

 and length of the bill ; thus, No. 32,1()7 measures .bO from nostril to end 

 of bill, instead of .60, as given below for No. 12,9 5. 



12.9u'5. Total lengih, 7.50; wing, 3.30 ; tail, 3.40, its graduation .45 ; ex- 

 poseu portion of 1st primary, 1.42, of 2d, 2. If), of longest, or 4tii (measured 

 from exjiosed ba.se of Ist primary), 2.45; length of bill from forehead, .90, 

 from nostril, .60; along gape, 1.07; tarsus, 1.02; middle toe and claw, .90: 

 claw alone, .25 ; hind toe and clan, .76; olaw alone, .35. 



This species is most nearly allied to C. brunneicapillus ; the most 

 apparent difference at first sight being in the greater concentration 

 of black on the throat and jugulum in brunneicapillus, and the much 

 smaller size of the remaining spots on the under parts, with the de- 

 cided light cinnamon of the posterior portion of the body. The outer 

 and central tail feathers alone are marked as in G. ajffinis, the inter- 

 mediate ones being entirely black, with the exception of a white 

 Bubterrainal band. 



This is one of the most characteristic birds constituting the 

 isolated Fauna of Cape St. Lucas. Like nearly all the species 

 peculiar to this remarkable locality, it is exceedingly abundant, 

 breeding in immense numbers. It has not yet been detected else- 

 where, though it may possibly be found on the lower Colorado.
