ON THE GEOGRAPHICAL DISTRIBUTION 
2. TURACUS CORYTHAIX (Wagl.) (ALBOCRISTATUS, Strickl.) 
“ Habitat, South-west Africa.” This species, described by Le 
Vaillant, Forster, and others, as numerous in Cape Colony, appears 
also to occur high up on the east coast, for Bianconi* of Bologna, in 
his rather inaccessible work, “ Specimiua Zoologica Mosambicana,” 
p. 34, part iii., very clearly describes a specimen sent by Formasini 
from Mozambique. 
3. TURACUS MACRORHYNCHUS, Fraser. 
“ Habitat, East Africa. ? ” We have lately received the most 
satisfactory information in regard to the habitat of this species. 
Dr. Thomson, one of the naturalists of the late Niger Expedition 
from England, collected this species in the forests of the West African 
island Bimbia, and off the Cameroon Coast, and relates concerning 
it as follows (p. 290 of the 2d vol. of the “ Narrative of the Expe- 
dition, sent by H. M. Government to the River Niger).” “ We were 
so fortunate as to procure from the same tree three specimens, each 
having the crest in a different state ; in one it was simply green ; 
in another green with a black margin ; in the third green with 
a thin line of black margined over all with purple. In all other 
respects they had the same plumage. It is quite clear to us, they 
were merely of different ages.” For a second statement, as to the 
locality of this species, we are indebted to C. Sundevall, according 
to whom, a specimen, brought by Afzelius from Sierra Leone, is to 
be found in the Stockholm Museum : “ Foglar fran Sierra Leone.’ 
Ofversigt af Kongl. Vetenskaps-Academ. Forhandlingar, 1849, 
p. 160. Here however it is said — “ Apices nigri e filis discretis 
plumarum cristae, fere 5 mm. longi cum spatio brevissimo intermedio 
( libido , vix nisi attente observanti apparent ; nullum vero margineni 
nigrum formant ; an detriti ?” 
* The species of Honey-sucker described in the same place, and named Cinnyns 
discolor , Vieill. ? is a new one : “ Macula scapular! nitidissime violacea,” well dis- 
tinguished from discolor. We propose to call it C. bianconii.
