This species, described by Sir Andrew Smitli (1. c.) is smaller 

 than its relative the M. africatia^ and dwells in similar lo- 

 calities. In Natal, Mr. Ayres found them abundant on Sea Cow 

 Lake, and if they approached any of the larger species they 

 were immediately chased away, and there was constant squab- 

 bling between them. One habit this bird possesses is pccidiar, 

 that of dipping the head up and down like some of tiie small 

 Plovers. Like AI. afrlcaiia^ Amlersson says, it docs not occur 

 in Great Namaqua-Land, is rare in Damara-Land, but common in 

 tlie Lake regions, antl on the Okovango, where it breeds. 



As this species has the head fully feathered it cannot very well 

 b- placed in the genus Afciopidins, with albimicha and africanns^ 

 which have the top of the head more or less bare of feathers, 

 and I have therefore proposed the term Aphahis (a<J)aXos) foi' 't. 

 with the following characters. Head completely feathered. No 

 wattles or fleshy crest upon the head. First and second prima- 

 ries longest, third, fourth and iifth equal. Closed wing reaches 

 to near the tip of tail. Tarsi strong and sliort. Bill straight, 

 slender, wedge-shaped at tip. 



Hydralector gallinaceus.
