The colouring of Wahlberg's specimen is intermediate between the 

 dark specimens collected by Mr. T. Ayres at Potchefstroom, in June and 

 October, and the pale ones obtained by Andersson in Ovampoland and Great 

 Namaqualand in June and November. 



The Red-billed, Short-toed Larks inhabit German South- 

 west Africa and the Transvaal. 



Andersson writes : " This Lark is not uncommon in 

 Ondonga ; before the breeding season they are seen in small 

 flocks, but are less observable after they are paired. A pair 

 which I watched occupied about eight days in constructing 

 their nest and in the female laying her eggs, which I took on 

 March 31st, after they had been incubated about three days. 

 The nest is formed in a hole excavated to the depth of about 

 two and a half inches, and thickly lined with decomposed 

 grasses." He obtained a specimen at Ondonga in November, 

 and several in Grreat Namaqualand in May and June ; besides 

 these there are in the British Museum two specimens from 

 Potchefstroom and the neighbouring Magaliesberg range, the 

 latter being one of the types from Wahlberg's collection, so 

 that the most eastern range known for this species is about 

 29° E. long. All Mr. T. Ayres' specimens came from the 

 Potchefstroom district, where he procured them in June and 

 August ; he writes : " Daring the month of August, 1881, these
