COLLURIO. 437 
Famity LANIID A. 
The diagnosis on page 322 will give a general idea of the characters 
of this family, as represented in the New World, especially as com- 
pared with its allies the Vireonidz and Ampelidx. The only genus 
found in America is that of typical “ Zanius,” and from which I have 
drawn the family characters, although as given above they are in 
general rather those of the Lanwine. 
Enneoctonus, of which Europe has several species, differs in much 
less rounded wing, the first quill about one-third the longest, the 
second about equal to the fourth; the tail shorter than the wing, 
and much less graduated; the bill more feeble. In the specimen 
before me of Hnneoctonus collurio there is no indication whatever 
of division of lateral plate of tarsus, and the nostrils are scarcely 
concealed.

Body robust. Wings rather shorter than the much graduated tail (the 
lateral feather about three-fourths the central). Primaries ten; the lst about 
half the 2d, which is 
longer than the 7th, the 
outermost slightly sinu- 
ated at end. Bill very 
powerful, deep and much 
compressed, both out- 
lines much curved and 
convex ; the upper man- 
dible decurving into a 
strong hook with a deep 
notch behind it, followed 
by a prominent tooth; tip 
of lower bill obsoletely 
similar. Nostrils almost 
circular, placed nearly 
opposite middle of com- fenea Collurto excubitoroides.
