^•j-MuSCISAXICOLA MACULIROSTRIS. 
On the 2nd December I met with two pairs near the river 
Sengelen. They do not appear to be eommon, and frequent 
rough rocky ground^ perching on large stones^ from which they 
sally in pursuit of insects. The male and female are alike. 
The nest is of grass lined with feathers and wool^ and placed 
on the ground under a large stone. 
Iris wood-brown j upper mandible blacky basal half of lower 
mandible yellow_, the rest black j legs and feet black. 
CeNTRITES NIGER. 
Partially resident; but the great majority migrate north¬ 
ward at the approach of winter. Males of this species were 
eommon at Chupat throughout September and during the 
first few days of October. On the 5th of the latter month I 
observed the first females, which gradually increased in num¬ 
bers. I found both sexes abundant near Lake Colguape, in 
the valley of the Sengel, and in sheltered places on the hills. 
When I returned to Chupat in December many had gone. 
Iris wood-brown; legs, feet, and claws black.
