Prof. Brandt on Siberian Birds described by Latham. 113 



As Mr. Macgillivray's observations on some specimens of Farcimia 

 which occurred to him at Aberdeen would appear to throw some 

 doubts upon the genuineness of this species, I have been induced to 

 re-examine carefully my specimens of Farcimia, and the result has 

 been, that in no case have I found other than rhomboidal cells on 

 those of Farcimia salicornia, or spathulate, or modified spathulate, on 

 those of F. sinuosa, or as I have now named it, F. spathulosa, a term 

 which expresses a more positive character of the species than the 

 other. The modified spathulate cells do indeed approach somewhat 

 to a rhombic form, but are not perfectly so, and these I have only 

 noticed in three or four of the basal, imperfectly developed internodes 

 of a single specimen. My opinion, therefore, of the validity of this 

 species remains unshaken ; indeed, the great difference in the size of 

 the internodes affords a character sufficiently distinctive, when there 

 are no other differences between the species. 



XIX. — On certain species of Siberian Birds described by 

 Latham, but which have hitherto been insufficiently deter- 

 mined. By Prof. J. F. Brandt of St. Petersburg. (Com- 

 municated by H. E. Strickland, Esq., M.A.) 

 [Being very desirous that some light should, if possible, 

 be thrown on the numerous nominal species of Siberian birds 

 recorded in the works of Latham, I prepared a list of all the 

 so-called species from Asiatic Russia, which appeared to be 

 unknown to the modern ornithologists of Britain. This list 

 I forwarded to Professor Brandt of St. Petersburg, the learned 

 author of c Descriptions et Icones Animalium Rossicorum,' 

 and of numerous other zoological memoirs, who has obligingly 

 transmitted to me the letter which is here translated.— H. E. 

 Strickland.] 

 Sir, 

 You have had the goodness to send me a list of those spe- 

 cies of birds in the c Index Ornithologicus ' of Latham which 

 appear obscure to modern ornithologists. Accept my sincere 

 thanks, together with a short notice of some of these species 

 which I have been enabled to decypher, or which have been 

 already correctly placed by other naturalists. 



I have the honour, &c.
