86 Mr. B. Alexander —An Ornithological 
with occasional snatches of song, but never allowing him to 
come to close quarters. At another time it will glide 
surreptitiously from a thick retreat to the next impenetrable 
spot, to dart away, if suddenly startled, with a twisting 
flight, its bright-coloured breast catching for an instant the 
sunlight. 
Regarding its distribution along the river, we observed 
the first individual at Chicowa, and from thence, as we 
journeyed on, it became more plentiful, especially in the 
neighbourhood of Zumbo. 
The female has no song, but utters now and again a soft 
whistle. In point of size she is considerably smaller than 
the male. 
Three of our specimens have the following measurements : 
Adult $. Total length (measured in flesh) 7'8 inches, 
wing 3'9, tail 3*8, culmen 0 65. 
Adult S • Total length (measured in flesh) 7’64 inches, 
wing 3*8, tail 3 65, culmen 0 06. 
Adult ? . Total length (measured in flesh) 7 inches, 
wing 3*3, tail 3*4, culmen 0‘54. 
106. Daulias Philomela (Bechst.). 
We first observed the Thrush-Nightingale at Zumbo on 
Dec. 17, and, though not common, we met with it now and 
again in the reed-beds and swampy places on our way up 
to the Kafue river. We remember having heard on one 
occasion (Dec. 22) the bird sing, and the notes appeared to 
us quite as rich and mellow as those of our Nightingale. 
Adult S • Total length (measured in flesh) 5-9 inches, 
wing 32. Iris brown ; bill brown ; base of lower mandible 
light horn-colour ; legs and feet brown. 
Adult $ . Total length (measured in flesh) 6 inches, 
wing 35, soft parts as in male. 
107. Turdus libonyanus (Smith). 
Adult S (near Senna, July 30, 1898). Total length 
(measured in flesh) 9*4 inches, wing 4*3, culmen 0 7. Iris 
black ; bill light orange; legs and feet light orange-yellow. 
Adult $ (Chisliomba, Oct. 21, 1898). Total length
