going outside, was just in time to get a flying shot at the 

 retreating bird — but missed it. Those who have had a 

 similar experience can imagine my feelings when that bird 

 disappeared. I knew, beyond any reasonable doubt, that it 

 was^. cedrorum, yet the lack of any positive evidence of 

 the fact, left me brooding over my disappointment for the 

 next two hours. The unexpected reappearance of the bird, 

 however, quickly dispelled the gloom. This time I took all 

 possible precaution, and succeeded in making this hand- 

 some addition to my collection of Guadalupe stragglers. 



DATA OF SPECIMEN COLLECTED. 



Remarks— No wax tips. 



23. Lanius ludovicianus excubitorides. 



White-rumped Shrike. — Two specimens of these butcher- 

 birds were seen on the central part of the island. Both 

 were heard singing in low, liquid tones, quite pleasing to the 

 ear. They were very shy, although to a less degree tlian 

 birds of the same species which were met with in 1885 on 

 Cerros Island, Lower California. 



Considering the abundance of larvae, coleopterous insects 

 and occasional grasshoppers, one would suppose that the 

 *'menu" of the Shrike left nothing for her to desire, but 

 on dissecting a specimen, I found amongst the caterpillars, 

 which the distended gizzard contained, a tiny golden foot of 

 Guadalupe's sweetest songster, the Dusky Kinglet. 



In color this bird is much lighter than the same species 

 from Oakland, Cal., and more closely resembles specimens- 

 from Tulare, Cal., and Tucson, A. T.
