There are several specimens of this species, hut none were in 

 the Smithsonian collection at the time Prof. Baird had this 

 genus under examination to include in his " JRi vii wqf Ann ri- 

 can Birds." In this he states (page losj that it "belongs to 

 the same section as C. hrumieicajrillus, etc., with reddish-brown 

 head, and hack striped longitudinally with white." 



It differs from C. brunneicajrillus in its smaller size, and long- 

 er bill, the under mandible whitish ; the feathers of the head 

 are brownish-black, with light rusty-brown margins, the head 

 of Irvnneicapillus is of a uniform dark reddish-brown ; the up- 

 per plumage of guttatus is less rufous, with the white shaft 

 stripes broader and more conspicuous, the spots on the chin 

 and throat are small and sparse, in the other species this part 

 has a dense agglomeration of black spots ; the sides arc haired, 

 not spotted, and the abdomen is without the rufous coloring of 

 C. brunru ica/piUus.
