point as far from the eye as this is from the tip of the lower mandible. The under parts are 
more bluish on the sides. There is a white patch on the inner web of the secondaries at the 
base, which extends nearer the margin along the inner towards the tip, and is distinctly and 
sharply visible from above. In excubitoroides this is seen on the under surface only ; in 
ludovicianus not at all. The most striking difference is in the much larger bill, which measures 
.75 of an inch in a straight line from base above to point, instead of .60. The nostril is .60 of 
an inch from the tip, not .46. This bird has been referred to L. elegans of Swainson, 1 but 
seems to differ in some appreciable points. 
The Lanius mexicanus of Brehm, (Cabanis' Journal, II, March, 1854, 145,) though similar 
to ihe^excubitoroides, yet appears to differ specifically both from this and elegans. Lanius 
nootlca (Grmelin, I, 309) has not been identified in later times. It evidently is not a true 
shrike, however.

'Lanius elegans, Sw. — White-winged Shrike. 
Lanius dedans, Sw. F. B. A. II, 1831, 122.— Nuttall, Man. I, 2d ed. 1840, 287— Gambel, Pr. A. N. So. I, 1843,

Clear bluish gray beneath unspotted white, with a frontlet of the same color with the head ; a broad white band across the 
wing ; a slender and very cuneiform tail, entirely bordered with white ; the second quiil feather longer than the sixth, the 
fourth the longest ; and tarsi exceeding the length of the bill, (measured from the angle of the mouth,)
