point as far from the eye as this is from the tip of the lower mandible. The under part 

 more bluish on the sides. There is a white patch on the inner web of the secondaries a 

 base, which extends nearer the margin along the inner towards the tip, and is distinctlj 

 sharply Tisible from above. In excubitoroides this is seen on the under surface only 

 ludovidanus not at all. The most striking difference is in the much larger bill, which meai 

 .75 of an inch in a straight line from base above to point, instead of .60. The nostril is . 

 an inch from the tip, not .46. This bird has been referred to L. elegans of Swainson, 

 seems to differ in some appreciable points. 



The Lanius mexicanus of Brehm, (Cabanis' Journal, II, March, 1854, 145,) though sii 

 to ihe'^' excubitoroides, yet appears to differ specifically both from this and elegans. Lt 

 nootha (Gmelin, I, 309) has not been identified in later times. It evidently is not a 

 shrike, however.
