Buceros erythrorhynchus, var. leucopareus, Ehr. fol. aa. 
The type, No. 15618, measures culmen 3*5 inch, wing 7*0, 
tail 8*2, tarsus 1*55. It is marked as having been obtained 
in Abyssinia. Another specimen of B. erythrorhynchus 
(No. 26), collected in Arabia by Hemprich and Ehrenberg, 
is labelled B. melanoleucus , Licht. 
Buceros hemileucus, Ehr. fol. aa , is, we consider, nothing 
but the female of B. forskalii. The type (No. 20) is from 
Abyssinia, and measures, culmen 3*8 inches, wing 8*75, tail 
7*8, tarsus 1*65. 
Buceros hemprichii, Ehr.fol. aa , = Buceros limbatus, Hupp., 
Gray, Hand-list, no. 7899, Ehrenberg^s name having priority 
(cf. Blanf. Geol. & Zool. Abyss, p. 326). The type is from 
Abyssinia, and is also labelled B. semirufus, Licht. 
Turdus musicus, var. planiceps, Ehr. fol. aa , does not dif¬ 
fer from the ordinary form of Turdus musicus. 
Saxicola monacha, Rupp. fol. aa. All the specimens col¬ 
lected by Hemprich and Ehrenberg are labelled L. gracilis , 
Licht. 
Saxicola xanthomeljEna, Ehr. fol. aa, is the eastern form 
of Saxicola rufa , and stands as Saxicola melanoleuca. There 
are two specimens from Nubia, both of which are labelled S. 
albicilla , v. Mull. This species is figured by Dresser in part xxv. 
of the f Birds of Europe/ 
Saxicola morio, Ehr. fol. aa, is a good species, being the 
eastern form of Saxicola leucomela, differing in having the 
under surface of the wing black and the crissum white. 
The specimens are from Upper Egypt and Arabia. 
Saxicola hemprichii, Ehr. fol. aa, differs from Pratin- 
cola rubicola in having more white on the tail; but this cha¬ 
racter is extremely variable, as in some specimens it extends 
from the base to within one third of the end of the tail, 
whereas in others it is barely visible. 
Saxicola aurita, var. libyca, Ehr. fol. aa, —Saxicola sta- 
pazina, L. (S. aurita auctt.)*. There are two specimens—a
