It must be evident to anyone who has read Smith's original description of Halcyon 

 swainsoni (cf. S. Afr. Quart. J. 1834, p. 143) that Dr. Reichenow is wrong in uniting 

 that bird with //. pallidiventris Cab. Smith writes that the " back, middle of the 

 wing, and tail are blue with a green gloss" in //. swainsoni, whereas in the present 

 form they are deep hyacinth-blue or purplish-blue. //. swainsoni is said to have been 

 procured in the interior of South Africa, a somewhat vague locality.

[The Senegal Kingfisher was plentiful in the acacia-forest on the plains around the 

 south end of Ruwenzori and was seen at Fort Beni on the edge of the Eturi Forest. 

 It was never found near water, but seemed to frequent only the rather dry country 

 covered with acacia-trees. It has a curious loud trilling note, difficult to describe. —
