Immature and young specimens are intermediate in color. 



The bill of this species is much more compressed and slenderer than in C. americana. The 

 ■ wings are more pointed ; the claws larger. The white hands on the wing distinguish the two 

 in all stages.

Bill very short, conical, and acutely pointed, the outlines even concave ; the commissure straight ; the base of the upper 

 mandible and the nostrils concealed by slifl', appressed bristly feathers ; middle of the mandible having several ridges parallel with 

 the culmen. Inner lateral toe rather tlie longer, its claw reaching the middle of the middle claw ; the hind toe rather longer, 

 its claw longer than the digital portion. Wings very long, reaching the middle of the tail ; second quill a little longer than the 

 first and third. Tail deeply forked. 



The specimens before me do not indicate more than one species, A. linaria, although the A.
