 tributes an interesting notice of the life and labours of the 

 much regretted Professor S. F. Baird. Some other papers 

 we leave unnoticed, as more especially interesting to Ame- 

 rican ornithologists ; but it is satisfactory to see that our 

 countryman and fellow-member of the B. O. U., Mr. John 

 Swinburne, is pi'obably the first ornithologist who has dis- 

 covered the nest and eggs of the Evening Grosbeak {Cocco- 

 thraustes vespertinus) in the Wliite Mountains of Arizona. 

 A female example of Falco tinnuncidus was shot near Nan- 

 tucket, Massachusetts, on Sept. 29, 1887, and examined 

 in the flesh by Mr. C. B. Cory; the first record of the 

 occurrence of our Kestrel in the United States. 



38. Buchner on the Birds of the St. Petersburg District. 



[Die Vogel des St. Petersbiirger Gouveruements. Von Eiig. Blicbuer. 

 Beitr. z. Kenntii. d. Riiss. Reiches, Folg. 3, Band ii.] 



In 1881 Messrs. Biichner and Pleske published a sketch 

 of the ornithology of the St. Petersburg Government, with 

 notes on 211 species of birds. Since that date so much new 

 information has been obtained that, without swelling the list 

 by the insertion of any species of doubtful occurrence within 

 the prescribed limits, the number now found therein has been 

 increased to 251. An Appendix contains a list of the species 

 which have been erroneously attributed to the district, accom- 

 panied by some remarks upon the introducers. A feature of 

 this excellent treatise is the evident care with which the 

 geographical distribution has been worked out. Those orni- 

 thologists who base the segregation of the White-spotted 

 and the Red-spotted Bluethroats upon the supposed complete 

 distinctness of their breeding-area, may be surprised to learn 

 that the White-spotted form does not stop short at the Vistula^
