LOBIVANELLUS. 



The immature example was obtained in Central Africa by Dr. Bohm and Herr 

 Reichard in the district of Marungu on the south-west shores of Lake Tanganyika ; and the 

 adults were shot by Mr. Johnston on the marshes of the Rio del Rey, opposite the island 

 of Fernando Po in the Gulf of Guinea. 



The black head, dark legs, and the chestnut-red on the pectoral band are characteristic 

 of Vanellus gregarius, whilst the position of the pectoral band, the absence of the hind toe, 

 and the presence of a wattle are characteristic of Lobivanellus cinereus, and the black 

 primaries of both. It seems probable that Bohm's Wattled Lapwing is the descendant 

 of a party of the ancestors of the Wattled Lapwing which emigrated into West Africa in 

 the company of a party of Unwattled Lapwings before these two sections of the family had 

 become sufficiently differentiated to make interbreeding impossible, and that it is the result 

 of a blend between the two which has retained some of the characters of each.
