1864.] COLLECTED BY CAPT. SPEKE IN EAST AFRICA. 107 
This is of course a very small proportion of an avifauna which 
probably contains from 500 to 600 species*, if not more. “But the 
collection is of value as being from a country of which we had pre- 
viously no ornithological knowledge whatever, though hardly suffi- 
ciently extensive to allow even of deductions from it as to the general 
character of the fauna. 
The following species in Capt. Speke’s collection seem to be with- 
out doubt new :-— 
Bradyornis spekit. Dryoscopus hamatus. 
Psalidoprocne albiceps. Vidua eques. 
Dryoscopus funebris. 
Of these, Bradyornis spekii, the two species of Dryoscopus, and 
Vidua eques have been already described by Dr. Hartlaub in the 
Zoological Society’s ‘ Proceedings’+. I now proceed to give a syste- 
matic catalogue of the entire collection, with a description of the 
undescribed species. Capt. Speke has added such particulars as his 
note-book or his memory could supply concerning each of them. 
It will be observed that the greater part of the species in Capt. 
Speke’s collection are such as have already been noticed as belonging 
to the East-African Fauna. There are, however, a certain number 
of southern species (such as Colius striatus, Numida mitrata, &c.) 
intermixed. 
Capt. Speke’s remarks on each species are added, and indicated by 
his initials. 
FaLconip&. 
1. Fatco TANYPTERUvS, Licht. 
Unyamuezi. One example: irides yellow. Shot at Kazeh by my- 
self.—J. H. 8. 
2. HyporriorRcHIs SEMITORQUATUS (Smith). 
Polyhierax semitorquatus, Smith, Ill. S. Afr. Zool. pl. 1. 
Hypotriorchis castanonotus, Heuglin, Ibis, 1861, pl. 12. 
One example, with the back slate-coloured, thus showing that 
Heuglin (Ibis, 1860, p. 407) is wrong in stating that all the northern 
examples are red-backed. See also ‘ Ibis,’ 1861, p. 346. 
Shot in Bogue, whilst sitting on a tree.—J. H. S. 
3. MELIERAX MONOGRAMMICUS (Temm.). 
M. musicus, P. Z. S. 1863, p. 105 (nec Daudin). This species 
was wrongly determined by me, and placed in Dr. Hartlaub’s list of 
the birds collected by Capt. Speke at Kazeh, as M. musicus. 
Irides yellow. Shot at Kazeh by myself, after it had just devoured 
a small lizard.—J. H. S. 
* Riippell’s ‘ Systematische Uebersicht’ gives 532 species as occurring in N.E. 
Africa, from Egypt to Abyssinia. Heuglin’s Synopsis (in the Sitzungsberichte 
Akad. Wien for 1856) enumerates no less than 754 species.
