These specimens and the dates for their collecting illu- 

 strate the wellknown, but nevertheless interesting, fact that 

 a number of very similar Turtle-doves with apparently similar 

 habits can live together in the same locality in tropical Africa.

The very interesting striped pattern of the head and 

 neck of the downy chicken has been mentioned by Reiche- 

 now (Vögel Afrikas I p. 438). It is very regular and exactly 

 alike in these two specimens. A mesial black band begins 

 at the base of the culmen, broadens gradually from the in- 

 terorbital region to the centre of the occiput, and narrows 

 then again towards the hind neck. From the postnasal re- 

 gion two more black stripes run backwards above the eye. 

 the outer one of these is double above the eye and ends in 

 The auricular region; the inner one extends down the sides 

 of the hind neck. From the corner of the mouth two black 

 stripes run backwards, the lower is shorter, the upper, which 

 also sends a side branch obliquely upwards and forwards 

 to the posterior corner of the eye, extends far down the 

 sides of the neck. The interspaces between the mesial and 

 the upper supraocular stripes are rich buff, but the lateral 

 interspaces are much paler, gradually becoming buffish white. 

 Along the middle of the back runs a broad blackish band 

 mixed with rufous, especially on the lower back. This is 



* The presence of similar white, triangulär, apical spöts in certain races 

 of the domesticated pigeon proves the general distribution within the genus 

 Columba of this pattern-
