and with the extraordinarily minute and careful observations 

 which must be necessary^ to present so intimate a picture of 

 the everyday life of these somewhat shy birds. 



The Garden Warbler is compared with the Blackcap^ to 

 which it is closely related in many respects, both in struc- 

 ture and habits. A good deal is said about the '^territory" 

 taken up by the males on their arrival in spring, where they 

 await the coming of the female, which is often a week or 

 ten days later. The male proclaims his appropriation of an 

 estate by incessant singing ; this goes on until the females 

 arrive and mating has taken place ; after this, Mr. Howard 

 remarks, there is a gradual decrease of song. 



The peculiar attitudes assumed during the period of sexual 

 activity are illustrated by three black-and-white plates of 

 the male and one of the female, and are described with 

 much detail. 



The present part also contains a coloured plate of the 

 Dartford Warbler and two photogravure plates of the Wood 

 Warbler.

The first half of this paper contains an account of Baron 

 Loudon's journey, extracted from his diary. Leaving Riga, 

 his home, on January 30, he reached the Black Sea on 

 February 4 and travelled on to Tiflis, where some little time 

 was spent. Thence he went to Talysch, the most south- 

 eastern corner of Russia, Ijing between the Caspian Sea 

 and the Persian frontier, where some time was spent in 

 collecting. Then crossing the Caspian, he travelled along 

 the Central Asian Railway to Samarkand and back to 

 Russia by the northern route via Orenburg, making many 

 side-visits at interesting places. 



With the assistance of his brother and cousin, and a 

 skinner, he was able to bring back some 2000 bird-skins as
