408 Dr. Heuglin on new oi- little-known Birds 



lines : these spots are absent on the first feather of the wnig, 

 but its entire outer margin is of a whitish colour. The prima- 

 ries, secondaries, tertiaries, and the tail-feathers have a rather 

 broad reddish-brown margin near the extremities ; the margin 

 is narrowest on the primaries, although sharply marked. The 

 under-coverts of the wings are greyish white, with blackish 

 transverse bands. The anterior side of the tarsus is covered 

 with feathers for one-third of its length. Bill, cere, a naked ring 

 round the eye, and tarsi yellow ; extremity of the bill bluish ; 

 the posterior and interior claws brownish, the middle and exte- 

 rior yellowish; the iris is yellow*. The second primary is the 

 longest, the first and third are rather shorter. 



I know nothing of the habits of this rare bird. Up to the 

 present we have received it only from the environs of Mere 

 [i. e. mountain) Belenia, on the White Nile, and I do not believe 

 that it ranges beyond lat. 5° N. It is partial to tall trees with 

 thick foliage — for instance. Tamarinds and IMimosas, and pro- 

 bably, like H. semitorquatus, feeds on small birds, lizards, and 

 coleoptera. The female appears to be scarcely different from 

 the male. 



The other species of Hypotriorchis which I have observed in 

 North-Eastern Africa are the following : — 



1. H. SUBBUTEO. 



Sometimes seen in Egypt during the winter ; but it appears 

 to be found there all the year through. I killed two old birds 

 in the months of June and August 1852, in Siut (Upper Egypt), 

 and in Dongola. 



3. H. ELEONOR^ (Gene). 



Rare, and only as a migratory bird in jVubia and on the Blue 

 Nile, but frequent on the madrepore islands of the different parts 

 of the Red Sea. In the month of August 1857, I found three 

 nests in the Archipelago of Dahlak, some of which contained 

 young birds quite recently hatched. (Cfr. Hartlaub in ' Ibis,' 

 1859, p. 338.)
