HETERHYPHAN'TES DORSOMACULATUS 377 



Dr. Sharpe adds : " One of the most interesting of Mr. 

 Jackson's discoveries in the field has been that this Black-and- 

 yellow Weaver has a chestnut-headed male, which appears to 

 me to be Sijmplectes croconatiis of vSjostedt, hitherto known 

 only from the Camaroons. In mentioning this fact in 1897, 

 I accidentally referred to the species as Hetprliiiphantes 

 stephanophorus, from a too hasty examination of the numbers 

 on the plate in the 'Ibis' for 1891. The young male pro- 

 cured on July 7 resembles the adult female, but has the 

 black wing-coverts edged with 3'ellow and the yellow of the 

 back is paler, the entire under surface of the body being pale 

 lemon yellow. The crown and sides of the head are olive 

 green with black feathers intermingled, showing that in its 

 first full plumage the head is black, like that of the old 

 female. Even in adult males the amount of black on the 

 throat varies, and in one of them the throat is entirely 

 yellow."

The Mottle - backed Black - winged Weaver inhabits 

 Camaroons. 



The species was discovered by Mr. Zenker at Jaunde and 

 is known, I believe, by the type only. On comparing the 

 figure of this specimen with that of the type of IT. inslgnu 

 (Ibis, 1891, pi. 6, fig. 1), it appsars possible that this bird
