4. Glaucidium californicum, Sclater, P. Z. S. 1857, p. 4 : 

 Glaucidium infuscatum, Cassin, Birds Cal., Oreg., &c. p. 189 (nee 

 Temminck). 



This little Owl is quite distinct from the S. American passeri- 

 noides, as stated by Mr. Cassin himself, and from every other 

 Mexican or S. American species with which I am acquainted. Mr. 

 Cassin has called it infuscatum, imagining it to be the true Strix 

 infuscata of Temminck ; but I have no doubt that that name is cor- 

 rectly applicable to the S. American passerinoides. It occurs only 

 in the first part of Temminck' s 'Manuel d'Ornithologie ' (p. 97), 

 where the author says he intends to describe a Brazilian species 

 nearly allied to the European G. passerinum, under the title Strix 

 infuscata. It is quite evident that he afterwards changed his mind 

 on this point, and called the same bird passerinoides when he came 

 to figure it in the ' Planches Coloriees.' Under these circumstances, 

 therefore, it is not correct to apply the term infuscatum to the Cali- 

 fornian species.

7. Lanius excubito rides, Sw. Northern Zool. p. 123. pi. 34. 



This appears to be the western representative of L. ludovicianus. 

 It has been often united with that species by modern writers, but, 

 I believe, erroneously, being easily distinguishable by its whitish 

 rump. In Texas both the two species seem to be equally abundant.

 Expedition, p. 76. 



8. TURDUS MIGRATORIUS (L.). 



9. Toxostoma redivivum, Gamb. Journ. Ac. Sc. Phil. i. p. 42. 



There are, I believe, four species of this curious form now known 

 to occur within the limits of the United States, (1) the present T. 

 redivivum (Cass. B. Cal. pi. 42) from California ; (2) T. lecontii 

 (Lawrence, Ann. Lye. N. Y.) from the Rio Hila ; (3) T. curvirostre 

 (Sw.) (Pomatorhinus turdinus, Temm., T. vetula, Wagl.) from 

 Mexico and Texas ; (4) an undescribed species in the collection of the 

 Smithsonian Institution at Washington, discovered during one of the 

 recent expeditions in New Mexico.
