first three longest, (first rather shorter,) and abruptly longer than the fourth. The tail is 

 moderately forked. Tlie tarsi are quite short. 



This species is very seldom seen in collections, though prohahly not rare in Georgia and 

 Florida. It is said to have been shot in Massachusetts, though this seems hardly probable. 



List of specimens. 



HELMINTHOPHAGA, Cabanis. 



Helminlhophaga, Cabanis, iMus. Hein. 1850-1851, 20. Type Sylvia rvficnpilla. 



Ch. — Bill elongated, conical, very acute ; the outlines very nearly straight, sometimes slightly decurved ; no trace of notch 

 at the tip. Wings long and pointed ; the first quill nearly or quite the longest. Tail nearly even or slightly emarginato ; 

 short and rather slender. Tarsi longer than the middle toe. 



The species of this section are well characterized by the attenuation and acuteness of the bill, 

 and the absence of any notch. There are, however, considerable subordinate difierences in the 

 different species. In some the bill is larger and more acute than others ; in one species, the 

 H. peregrina, the wings are unusually lengthened, the tail being only about seven-twelfths as 

 long.

 found on page 251.
