1921.] Genus Macrosplienus Cassin. 
flavicans ugandae van Someren. 
This form was described from Mabira (Bull. B. O. C. 
xxxv. p. 126), and is said to inhabit the Uganda forests. 
It is darker than the typical form and is richer yellow on 
the underside. 
The only other species in the genus besides M. flavicans 
and its subspecies are :— 
Macrosplienus kretschmeri Rchw. & Neumann (Orn. Mon. 
1895, p. 75—Kiboscho), of which I have never seen a 
specimen and which is only known to occur in the Kili¬ 
manjaro region; likewise Macrosplienus griseiceps Grote 
(Orn. Monatsber. 1911, p. 162—Mikindani, late German 
E. Africa), compared by the author with M. kretschmeri , 
and M. albigula Grote (Orn. Monatsber. 1919, p. 62— 
Mlalo, Usambara, Tanganyika Territory). I have not seen 
specimens of either. 
Macrosplienus kempi (Sharpe) and Macrosplienus 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 Amaurocichla kempi Sharpe from the genus in 
which Sharpe placed it and put it in the genus MacrosphenuSj 
as it is evident that it has nothing whatever to do with 
Amaurocichla hocagei. 
The bird figured as Amaurocichla kempi (Ibis, 1905, 
plate v. facing p. 231), named and placed in the genus 
Amaurocichla by Sharpe (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 :— 44 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, and 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 differs markedly from Amaurocichla bocagei.
