Birds of Gazaland, Southern Rhodesia. 307 
frequenting my gum-trees come readily to any food which 
may be thrown down. The call resembles the syllables 
“ku-kéro! ku-koro!?’ often repeated, the middle one long- 
drawn. The birds in my aviary frequently call at night. 
165. Turtur senucatensis. Laughing-Dove. 
A Dove which J shot in the open bush of the Umswi- 
rezi Valley on the lst of November was, I think, undoubtedly 
referable to this species. The skin was unfortunately lost. 
166. Cina carensts. Namaqua Dove. 
Rather locally distributed, appearing to prefer grass-jungle 
country : I found it common enough in the Shikamboge 
Valley in the winter of 1899, and it is plentiful on the 
Jihu-covered hills between Spungabera and the Inyamadazi, 
a few miles east of Chirinda. 
167. Haptoperia tarvata. Lemon-Dove. 
Extremely common in Chirinda, though more fre- 
quently heard than seen, for it 1s exceedingly shy and keeps 
closely to the undergrowth when startled from the ground 
where it has been feeding. Several stomachs examined 
contained the seeds of such trees as happened to be fruiting, 
and in one case tender green leaves—with, usually, a few 
small snails, the shells aiding, I imagine, in digestion, for 
grit must be somewhat hard to obtain in the loamy soil of a 
great portion of the forest. I have kept as many as thirty 
of these Doves in a large aviary at one time, and though 
they finally lose their excessive fear of a human being, 
they remain extremely nervous, a very slight alarm at night 
being sufficient to set the whole number in a senseless 
flutter. This disturbance, once started, is repeated at fre- 
quent intervals till morning, when two or three of the 
birds may be found on the ground in an exhausted condition, 
They are unusually gentle and sweet-tempered for Doves, 
and, were it not for this unfortunate neryousuess, would 
make excellent pets. 
I have noticed two distinct types—one duskier as regards 
both breast and forehead; the other and, I should say,
