So far back as 1885 I received from Malta a very fine 

 specimen of Falco barbarus, and I thought that I had re- 

 corded its occurrence. But Count Salvadori, who lately 

 examined the specimen, remarked that he had not seen any 

 record of it ; and finding that I have never mentioned the fact, 

 I take this opportunity of repairing the omission. The speci- 

 men was sent to me by Dr. David Bruce, who was then 

 quartered at Malta. He wrote to me statiug that he had 

 purchased it in the flesh in the Valetta market on the 

 32nd April, 1885, and not knowing what it was, sent it

 slightly marked with a few dark stripes. 



In 1885 the late E. F. von Homeyer described as a new 

 species (Zeitschr. f. d. gesammte Orn. 1885, p. 185, pi. x.) a 

 Flycatcher intermediate between Muscicapa atricapilla and 

 M. collar-is, under the name of Muscicapa semitorquata, and 

 stated that this form or species was the only one found in the 

 Caucasus, and that he had examined six specimens from 

 there, all of which agreed closely inter se. 



I find, on looking over my series, that I possess one speci- 

 men of this form, an adult male, from Ortakeuy in Turkey, 

 obtained by Robson on the 6th April, 1865, which agrees 

 exactly with von Homeyer's description and plate. It appears
