Some examples, possibly young or possibly in non-breeding 

 plumage, have a white chin and distinct spots of black on the 

 throat, and it was on these characters that the species was 

 distinguished by Reichenow. 



Range. Cameroon. There is a good series of this form 

 collected by Bates in the Museum. 



4. Serinus mozambicus barbatus. 



Crithagra barbata Heuglin, J, f, 0. 1864, p. 248: Djur, B.G. 



Resembles S. m. punctigula, but is distinctly a brighter 

 yellow below and on the forehead and wing-coverts. It is 

 very close to S. m. punctigula. 



Range. Bahr el Ghazal east to Mongalla and Lado, west- 

 wards to the Krebeji, French Congo {Alexander), and south 

 to Ruwenzori and Uganda. 



5. Serinus mozambicus aurifrons, subsp. n. (ex Heugl. 

 Syst. Uebers in SB. Akad. Wien, 1856, p. 293 : Sennar.) 



This form comes near S. tn. barbatus, but is considerably 

 paler and greyer on the back, and the yellow of the lower 

 parts, forehead, and tips of the wing-coverts is also paler. 

 The tips of the tail-feathers are whitish yellow, and the 

 yellow of the forehead is generally much broader. The 

 moustache-streaks are finer and less pronounced. 



We have adopted Heuglin's name, which is without 

 description, for this form, and this must be regarded as its 

 first description. 



Range. Sennar and probably Kassala, extending to north 

 Abyssinia. 



The birds from Shoa and south Abyssinia should probably 

 be referred to this form. They appear to be slightly darker 

 and with less yellow on the forehead than the more northern 

 birds; but the s|)ecimens are not in sufficiently good condition 

 to be certain. They are, however, easily distinguishable from 

 S. m. barbatus, vfith. which they were identified by Neumann 

 (J.f. O. 1905, p. 354) and O.-Grant (Ibis, 1913, p. 583). 



6. Serinus mozambicus hartlaubi. 



Crithagra hartlaubi Bolle, J. f. O. 1858, p. 355 : W. Africa. 

 This form is at once distinguished by its grey head. 

 Range. Senegal to northern and southern Nigeria.
