1 92 1.] Genus Macrosphenus Cassin. 123 



M. flavicans ugandae van Someren. 



Tliis form was described from jNIabira (Bull. B. O, C. 

 XXXV. p. 126)j and is said to inhabit tlie Uganda forests. 

 It is darker than the typical form and is richer yellow on 

 the underside. 



The only other species in the jjeuus besides M. jiavicans 

 and its subspecies are : — 



Macrosphenus kretschmei-i Rchw. & Neumann (Orn. Mon. 

 1S95, p. 75 — Kiboscho), of which I have never seen a 

 specimen and wiiich is only known to occur in the Kili- 

 manjaro region; likewise Macrosj>henus griseiceps Grote 

 (Orn. Monatsber. 1911, p. 162 — Mikindani, late German 

 E. Africa), compared by the author with M. kretschmeri, 

 and M. alblgula Grote (Orn. Monatsber, 1919, p. 62 — 

 Mlalo, Usambara, Tanganyika Territory), I have not seen 

 specimens of either. 



Macrosphenus kempi (Sharpe) and Macrosphenus concolor 

 (Hartl.), concerning which two forms the following remarks 

 may be of interest : — 



In the first place I wish to transfer the bird hitherto 

 known as Aniaarocichla kempi Sharpe from the genvis in 

 which Sharpe placed it and put it in the genus, Macrosphenus^ 

 as it is evident that it has nothing Avliatever to do with 

 Aniaarocichla bocagei. * 



The bird figured as Amaurocichla kempi (Ibis, 1905, 

 plate V. faciiig p. 231), named and placed in the genus 

 Amaurocichla by Shstrpe (Bull. B. O, C. xv. p. 38, 1905), 

 cannot in my opinion be assigned to that genus, although 

 Sharpe was himself the author of the genus Amaurocichla. 

 The generic characters. are given by Sharpe in P, Z. S, 1892^ 

 p. 228, and are as follows : — " Similar to Crateroscelis, but 

 distinguished by the shape of the wing^ the first primary 

 being nearly as long as the second. Additional characters 

 are :^The bill is as long as the head, aiul rictal bristles are 

 absent, while the tail-feathers are somewhat acuminate.^' 

 The type of the genus is Amaurocichla bocagei. 



Now, the bird which has hitherto been known as Amauro- 

 cichla kempi ditl'ers markedly from Amaurocichla bocagei.
