Bill (exposed culmen) 18, wing 90, tarsus 22*5 mm. 



0^5. Five males and two females of this new race are in 

 the British Museum. 



In the 'Ibis,' 1915, p. 101, when publishing the results o£ 

 Boyd Alexander's investigations in the island of St. Thomas, 

 Gulf of Guinea, I identified the Grey-headed Serin-Finch 

 which he obtained there as Serinus Jiartlaubi. Hecently 

 Messrs. Sclater and Praed ('Ibis,' 1918, p. 467) pointed out 

 that the birds which I then named S. hartlaubi did not exactly 

 agree with any mainland race. Taking into consideration 

 the isolated position of this bird, and that it will probably 

 become even more differentiated as time goes on, I propose 

 to name it : — 



Serinns mozamhicus santhome, subsp. nov. 



Adult male. Most nearly allied to S. m. tando (N. Angola), 

 from which it differs in having the upper parts less conspi- 

 cuously streaked, especially on the crown of the head. 

 Distinguished from S. m. caniceps (Seuegal-S. Nigeria) by 

 having the head green instead of grey. From S. m. pimcti- 

 gula (Cameroon) it is distinguished by lacking the bright 

 green back of that race. 



Bill 8, wing 65, tarsus 14 mm.

 12.23. 3951. St. Thomas Island, Gulf of Guinea, 23 Feb., 

 1909. Boyd Alexander coll. 



Anthreptes fraseri earner oonensis, subsp. nov. 



Adult male. Distinguished ivom. Anthreptes fraseri fraseri^ 

 from Fernando Po, by its duller underparts (more olive- 

 green and less yellow). It is also a smaller bird, although 

 the measurements overlap. A. f. cameroonensis (males) 

 64-73 mm. ; A. f. fraseri (males) 70-80 mm. 



Range. Ckmeroon and Gaboon.
