Observations ornithologiques par le Lieutenant-Colonel Roh. C. 

 Tytler de I'armee indienne, traduites par M. J. Veri-eaiuc. 

 Rev. Zool. 1870, p. 193. 



A French translation of some notes communicated by Col. 

 Tytler in letters to M. Verreaux relating to Indian species of 

 Corvus. A supposed new species, founded on specimens obtained 

 near Umballa*, is termed Curvus affinis, allied to C. corone of 

 Europe (p. 194). The same species, apparently, is subsequently 

 (p. 198) designated C. punjahensis (qu. punjabensis) ', and the 

 Raven of the Andamans is named C. andamanensis.

The first two parts of this article, which will be of great in- 

 terest if properly worked out, are taken up by general intro- 

 ductory remarks on the classification of birds, &c. The author 

 is assisted in his work by " D. Antonio Penifiel and D. Jesus 

 Sanchez, Pi'eparadores del Museo Nacional." We are glad to 

 hear of the existence of such an establishment in the Mexican 

 capital.

 viz. Ai'aclmechthra with 13 species, jEthopyga with 14, Nec- 

 tarophila with 5, Chakostetha with 6, Anthreptes with 1, and 

 Chalcoparia with 1. The synonymy and geographical distribu- 

 tion of every species is treated of very fully and with great care. 

 A list of several names applied by various writers apparently to
