Recently published Ornithological Works. 463 



examples were obtained. Four of these are new species or 

 subspecies, namely : — Sturnus caucasicus, Phyllopneuste lo- 

 renzii, Mecistura irbii var. caucasica, and Ruticilla erythro- 

 gastra var. severzovi. Seven species are additional to tlie 

 Caucasian list, namely : — Nyctale tengmalmi, Phylloscopus 

 nitidus, Sitta krueperi, Lusciola infuscata, Cuculus indicus, 

 Sturnus purpuras cens, and Locustella ncevia. The following 

 species are figured : — Ruticilla ochrurus, Sturnus caucasicus, 

 Carpodacus rubicUlus, Phylloscopus nitidus, Phyllopneuste lo- 

 renzii, and Tetrao mlokosieviczi, male, female, and young of 

 both sexes. Very interesting details are given respecting the 

 last-named species, and its trachea is figured, showing a re- 

 markable diversity from that of T. tetrix. Altogether this is a 

 very good piece of work, containing a mass of original personal 

 observations of great importance to students of Paleearctic 

 ornithology.
