 1 Jan., 1911. W. P. Lowe coll., presented by Capt. G. C. 

 Hardy, R.N. 



Bill 22, wing 58, tarsus 15 mm. 



Material examined : C. o. guineens'iSy 109 specimens from 

 West Africa (excluding the Belgian Congo) ; C. o. obscicra, 

 31 specimens from Fernando Po. 



The status of this new race will be discussed more fully in 

 the report on Mr. Lowe's Lagos Collection, rf. ' Ibis,' October 

 1921. 



Mr. Bannerman also sent the description of a new race of 

 the White-fronted Grosbeak- Weaver from Northern Angola, 

 of n Serin-Finch from St. Thomas Island, and of a Sun-bird 

 (AntJireptes) from Cameroon. 



He characterised these birds as follows : — 



Amblyospiza albifrons tandae, subsp. nov. 



Adult male. Most nearly allied to Amhlyosjnza albifrons 

 capitalba from the Gold Coast, from which it differs in its 

 larger size, the wings of males measuring 90-91 mm. (in 

 A. a. capitalba the wing measures 81-87 mm.), also by 

 having a considerably larger white speculum on the wing. 

 The coloration of the underparts is similar to A. a. capitalba. 

 As in all the races of A. albifrons, the new form shows con- 

 siderable variation in the tone of the chestnut of the head 

 and breast. 



It is noteworthy that this new race is separated geo- 

 graphically from the Gold Coast bird by Amblyospiza 

 albifrons saturata Sharpe, which inhabits Cameroon ; this is 

 a large race, but is distinguished at once from both capitalba 

 and tanihe by the much darker grey of the under surface. 



The female is intermediate in size between the females 

 of A. a. capitalba and A. a. saturata, which it resembles 

 in coloration. 



Iris dark brown ; feet purplish-black ; bill greenish-black.
