NOVITATES ZOOLOCICAE XXII. 1915. 247 



24. Otis (Neotis) caffra denhami Children 



c? ? ad., province of Zaria, 29. x., (i. xi. 1912. 



This magnificent pair of Bustards is of great interest. The wings of the male 

 measure (with tape measure) 63, those of the female 54 cm. The birds appear to 

 be typical denhami, agreeing with the type, which was collected during Denhara 

 and Clapperton's famous expedition to the Western Sudan, probably near Lake 

 Chad, and with specimens from Kordofan. 0. caffra caffra seems to be very close, 

 but to differ by having a white patch on the nape, while in denhami the rust-red of 

 the hind-neck reaches right up to the grey and black colour of the crown. In size 

 the South African form is similar or exceeding denhami, the wing of a male from 

 the Transvaal measuring about (io cm. 



Between the so closely allied northern and southern races appears to live 

 another of smaller dimensions. We have a female from Benguella (Langassim on 

 the road to Lobango, 17. i. 1906, Dr. W. J. Ansorge coll.). The wings measure 

 only .about 4.i-5 cm. 



Mr. Ku<lolf Grauer shot two males in Central Africa, 1 Kyiowa in Karagwe 

 (Bukoba), German East Africa, 2. vi. 1907. The wing measures barely 61 cm. 

 Anotlier male, shot 120 km. west of Lake Tang.anyka, 20. vii. 1908, is in moult, and 

 the wing cannot be measured with good results, but it appears to be still shorter. 



25. Otis (Trachelotis) seuegalensis senegalensis Vieill. 



2(J(?, 1 ?,Zaria, 2.x. 1912. 



Tiiere can be no doubt that Otis ( Trachelofia) barrorii is a more richly and 

 darker coloured subspecies of 0. scnei/aknsis. The wings of the Hausaland skins 

 measure : t? 271, 276, ? 274 mm. (measured on ruler). 



About other subspecies see Neumann, Journ.f. Orn. 1907. p. 307, who treats 

 as forms of O. senegalensis : 0. s. senegalensis, 0. s. somaliensis, 0. s. canicollis 

 and 0. s. barrorii. 



Riippell {Mas. Scnchenbcrg. ii. p. 230, pi. 15) and other ornithologists have 

 employed the name rhaad for this species. Gmelin and Latham based their rhaad, 

 entirely on the Rhaad of Shaw, Trav.and Observ.in Barhanj and Levant. The bird 

 figured by Shaw appears to me to be an Otis tetra,x, and his description refers to 

 the latter and another larger species, either the Great Bustard or Otis arahs, while 

 0. .senegalensis does not occur in Algeria. Latham said that Shaw's Rhaad in- 

 habited Arabia, but he described it from Algeria. 



26. Otis (Lissotis) melanogaster Riipp. 



c? ? , Zaria, without date. 



These specimens appear to be very small, compared with South African 

 specimens. A female, collected by Riggenbach in Northern Senegambia, is also 

 rather small. Probably there exists a smaller race in N.W. Africa.
