Adult male and female. Iris brown or dark brown ; bill black in male, lower 

 mandible brown in female ; feet brown. 



This Weaver was found breeding at Mokia on the 9th and the 25th of May. There 

 are full-plumaged males killed in November, December, April, May, and July. One 

 male specimen dated the 8th of December is in nearly full plumage, but still retains 

 some of the heavily black-striped feathers of the female plumage on the back, while 

 the uTiderparts are mixed with buff feathers. Another male specimen killed on the 

 5th of April, as well as a specimen marked female (No. 3321) obtained on the 4th 

 of May (in full male plumage, vide supra), have black shaft-stiipes to the feathers of 

 the mantle. 



This species ranges from Wadelai in the north to South liuwenzori in the south, 

 and extends eastwards to Entebbe. It is quite distinct from H. jacksoni Shelley, 

 which ranges from Arusha and Kilirranjaro to I;ake Baringo and Entebbe. Captain 

 Shelley states that there are in the Jackson Collection specimens of H. jacksoni 

 procured at Butiaba, on Albert Nyanza ; but this is certainly an error, as one of the 

 specimens in question, a full-plumaged male, is clearly referable to H. dimidiatus. 

 I have examined full-plumnged males of both species from Entebbe, where their 

 ranges meet. 



The adult male of H. jacksoni may be recognized by having the culm en nearly 

 straight, the black of the head continued on to the hind-neck, the mantle, like the 

 back of the neck, bright yellow, and the breast and belly deep chestnut. 



In H. dimidiatus the culmen is curved ; the black of the head does not extend 



* Marked " 5 ," hut with plumage hke that of the adult male, except that the black on the occiput is 

 mottled with reddish-orange and the back is striped.
