has a vertical median stripe ; the other section, represented by the South American 

 C. maninibe, has the tail-feathers normal and rounded at their ends ; the crown has no 

 median stripe. Both forms are represented in our region, but only C. passerinus and 

 its allies C. lecontii and C. henslowi are found in North America ; but these have a wide 

 range in the States, and G. passeriniis is found in several of the larger "West Indian 

 Islands. Of the southern section, C. petenicus is its only representative in Central 

 America ; but in the southern continent C. manimhe, in one or other of its somewhat 

 varied races, and C. peruanus are found throughout the whole of Tropical America, as 

 far as the Argentine Eepublic. 



The bill of C. passerinus is stout, the culmen curved and somewhat elevated towards 

 the forehead ; the nostrils are in a somewhat deep fossa, the upper part of which is 

 occupied by a membrane ; the tomia is rather concave, and beneath the nostrils the 

 bill is somewhat tumid ; the wings are short and much rounded, the second and third 

 quills being slightly longer than the first, fourth, and fifth ; the inner secondaries fall 

 short of the longest primaries only by one eighth of an inch ; the tail is rounded and 

 the feathers are narrow and pointed, but lax and not stiffened as in Ammodromus. The 

 general plumage is mottled above and plain beneath, but in the young the chest has 

 some faint streaks. The tail of C. petenicus consists of broader feathers with rounded 

 ends. The plumage is less varied above, and there is no vertical streak.
