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 tlie tip, and is distinctly and 

 sharply visible from above. In excubiioroides 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,' but 

 seems to differ in some appreciable points. 



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

 to the excubiioroides, yet appears to differ specifically both from this and elegans. Lanius 

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

 shrike, however.
