M. degeni and M. zomba with M. fischeri, but if he had ever 

 examined specimens of the two first named, he woukl have 

 doubtless recognised their very distinctive characters. [_Cf. 

 Trans. ZooL Soc. xix. p. 310 (1910).]

An immature example of the Singing Bush-Lark was 

 procured in Baroda, at 5000 feet, on the 12th of September. 

 This appears to be a rare species in north-east Africa. It 

 had previously been obtained by Mr. Hawker at Ujawaji, in 

 Somaliland, and by Sir Alfred Pease at Filwa, east of Addis 

 Abbaba ; the present record carries its known range about 

 two hundred miles further south. 



88. Mirafra p(ecilosterna. 



Mirafra pcecilosterna (Reichenow); Reichenow, iii. p. 331 

 (1904). 



This Sabota Lark was met with about the north end of 

 Lake Stefanie and on the Sagan River, 2000-2800 feet, in 

 August. The specimens all agree perfectly with typical 

 examples procured on the Tana River by Mr. Gilbert Blame ; 

 also with specimens from tlie Guaso Nyiro collected by 

 Mr. A. B. Percival and with others from the same locality 

 in Sir F. J. Jackson^s collection. 



Two birds in the latter collection from Kikuyu and the 

 Athi River have the upper parts much darker, and the 

 markings on the chest and the Hanks deeper rufous than 

 in typical M. pa;ci/usterna. They agree fairly well with the 

 figure given by Shelley and apparently taken from a speci- 

 men collected by Abbott east of Kilimanjaro, but the general 

 colour of the rufous portions of the plumage is of too rusty 

 a red. 



I propose to separate this bird subspecifically under the 



name
