has a vertical median stripe; the other section, represented by the South American 
C. manimbe, 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 C. passerinus 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. manimbe, 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 Republic. 
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.
