XVI. Supplementary Notes on the Curassows now or lately living in the Society's 
Gardens. By P. L. Scuarer, M.A., Ph.D., F.RS., Secretary to the Society. 
Read June 18th, 1878, 
[PLtates LXXXIX.—XCV.] 
SINCE I read my paper on the Curassows living in the Society’s Gardens, five years 
ago’, many additional examples of these birds have been received by the Society. From 
this source, and from the examination of specimens living in other Gardens, as also 
from the study of examples in several Collections and Museums, I am enabled to 
offer a few additional remarks, which, I trust, may tend to elucidate further the history 
of this difficult group. 
1. Crax ciopicera. (Plate LXXXIX.) 
Crax globicera, Linn. Scl. Trans. Zool. Soe. ix. p. 274. 
I have already mentioned the fact that at Panama the male of this species shows a 
slight white terminal margin to the tail, thereby approaching C. daubentoni. The 
female of the Panama form is likewise different from the same sex of the more 
northern bird, in having the tail blackish brown strongly barred with six or seven light 
cross bands, and terminated by a similar margin. ‘This is shown in Mr. Smit’s drawing 
(Pl. LXXXIX.), taken from a skin in the collection of Messrs. Salvin and Godman. 
In a skin from Costa Rica in the same collection the bands are likewise well defined, 
but much narrower. 
There are likewise examples of both sexes of the Panama form in the gallery of the 
British Museum, and in the Society’s living Collection. The latter are said to have 
been obtained at Cartagena, which is the most southern locality yet recorded for this 
species. 
2. CRAX ERYTHROGNATHA. (Plate XC.) 
Craz erythrognatha, Scl. et Saly. P.Z.S. 1877, p. 22. 
Purpurascenti-nigra, ventre imo crissoque albis; criste plumis nigris, recurvis ; loris 
nudis ; cera et rostro basali rubris; hujus apice flavicante; pedibus in pelle sicca 
pallide corylinis: long. tota 28:0, ale 16-0, caudz 11:0, tarsi 4:5. Fem. mari similis, 
sed cristz plumis fasciis minutis albis variegatis. 
Hab. Columbiam interiorem. 
Mus. §.-G. 
Obs. Similis C. alectori et omnino ejusdem forme, sed rostro rubro diversa.
