Mr. R. B. Sharpens Catalogue of Accipitres. 
Buteones, p. 24*); and in his supplement to this work {vide 
Accipitres,, p. 113)^ where he very unadvisedly, as I venture 
to think, unites as one species C. gallicus, C. heaudouini, 
and C. pectoraliSf he again mentions the same specimen, re¬ 
ferring to it in the following words:—Adulte, Senegal, 
1858, dessous en arriere du jabot d^un blanc uniforme, les 
autres parties plus foncees que d^ordinaire/^ The latter com¬ 
parison, no doubt, refers to the colour of the brown portions 
of the plumage being darker in this specimen than in C. gaU 
licus ; and the whole description entirely accords with the 
appearance of the adult C. pectoralis. 
Von Heuglin, who agrees with Schlegel in considering (7. 
pectoralis specifically distinct from C. cinereus, and the 
latter identical with C. funereus, describes the former, under 
tho specific name of thoracicus, at p. 84 of vol. i. of his ^ Orni- 
thologie Nordost-Afrika^s,' in exact accordance with adult 
South-African specimens, and adds some remarks respecting 
the localities where he met with it, of which the following is 
a translation :—The Pectoral Serpent-Eagle is not very 
frequent in the warmer parts of North-eastern and Central 
Africa; its most northern limit is, I believe, the Province of 
Dongola (Argo Island, August 1852) ; we obtained it in 
Abyssinia, on the Blue and the White Nile, and in Kor- 
dofan, but only from after the rainfall until the early spring/^ 
Under the head of C. cinereus, Von Heuglin remarks, at 
p. 85 of the volume already quoted, ‘^Werreaus explains the 
whole-coloured Serpent-Eagle as the young of C. thoracicus-^, 
with which view neither Schlegel, Von Pelzeln, nor I agree; 
the former is always larger, and has strikingly larger and 
stronger talons. We have examined many eastern and south¬ 
ern specimens, and the above comparison always holds good ; 
^ In the succeeding page Prof. Schlegel makes the following remark, 
under the head of C. cinereus :—Taille plus forte et pieds heaucoup plus 
vigoureux que dans les autres especes connn.es .... c’est decidement une 
espece particuliere, dont j’ai encore examine des individus aux musees de 
Berlin et de Francfort.”
