Weaver-bird, Ploceus rutledgii, is merely P. megarhynchus 

 Hume, in summer plumage. He also suspects that Munia 

 malaca interbreeds with M. atricapilla, and makes a sug- 

 gestion for a more natural division of the PloceidcBj from 

 the form of the culmen, into Ploceinaj and Sperraestinse, 

 He likewise records his experiments on sexual selection in 

 the Avadavat [Sporaginthus amandava).

 confluence of the Sija, in 63° 37' N. lat., and made a good 

 collection of birds, of which he gives an annotated list. 

 Phylloscopus borealis was found breeding, and at that time 

 had unfledged young. One of the most interesting Pas- 

 serines met with was Emberiza aureola, of which 21 examples 

 were obtained. It inhabits the meadows on the banks of 

 the Dwina, and has a short melodious song ; its nests and 

 eggs were taken.
