devoid of marked physical features. About Semlin much of 

 it is rich agricultural land, further west it is chiefly clothed 

 with extensive forests of old timber, mostly oak, and with 

 numerous marshes of greater or less extent. A few species 

 are added which were observed on the Danube betAveen tlie 

 confluences of the Drave and Save, where the river forms the 

 N.E. boundary of the province. Further research, and 

 especially an investigation of the Fruska-Gora mountains, 

 lying to the north-west of the distiict indicated, and attaining 

 probably a height of between 2000 and 3000 feet, would 

 add many species to the list, for the influence of elevation on 

 the avifauna of countries possessing similar physical cha- 

 racters is well known. 



The list having been compiled between the 18th of May 

 and the 2nd of June, it is fair to presume that all the species 

 noted were breeding in Slavonia. 



TuRDUs Musicus, Linn. 



We never saw this species, nor did we hear its song ; but 

 its nest and eggs were found in several of the woods. 



TuRDUS MERULA, Liuu. 



Did not appear to be a common species. Single birds 

 were noted at Vukovar, Dobanovci, and Kupinovo. 



SaXICOLA (ENANTHE (LiuU.). 



Very local, and only noted on some poor land near Semlin, 

 Dobanovci, and Becmen. 



Fratincola rubetra (Linn.). 



Only seen in the marshy meadows near Pijavicar, and, as 

 stated, was of a lighter type than ordinary British speci- 

 mens, having the breast and abdomen dull white. 



Fratincola rubicola (Linn.). 



A solitary male seen and obtained in a vineyard at Doba- 

 novci. An interesting specimen, in which the head and back 

 are intensely black, with the faintest trace of the rufous 

 edging to the feathers, the bay of the underparts is con-
