the Grand Cape Mount District,, some forty-five miles west 
of Monrovia. In this splendid but unhealthy district, Mr. 
Sala succumbed to the noxious climate in June 1881, and a 
year later Mr. Biittikofer was obliged, on account of broken 
heaith, to return to Europe. 
The fauna of Liberia, according to Mr. Biittikofer’s inves¬ 
tigations, has more similarity to that of Sierra Leone than to 
that of the Gold Coast. Psittacus timneh is the Liberian 
representative of Ps. erithacus, and Agapornis swinderniana 
of A. pullaria. 
Mr. Biittikofer's list of Liberian birds comprehends 162 
species, concerning which many excellent notes are given. 
Columba unicincta , Cassin, is figured. A map of the district 
explored is appended, as should be done in all articles on the 
animals of a particular locality. Altogether we consider 
this paper a model of what such a memoir ought to be. 
6. Buttikofer on Glareola megapoda. 
[A Supplementary Note on Glareola megapoda. By J. Biittikofer. 
Notes Leyden Mus. vii. p. 256.] 
A note received from Dr. Guillemard tends to confirm the 
distinctness of this species, which was called by Schlegel 
Glareola nuchalis liberice. 
7. Cazin on Plotus melanogaster. 
[Note sur la Structure de l’estomac du Plotus melanogaster. Par M. M. 
Cazin. Ann. d. Sci. Nat. xviii. art. 8.] 
The author, in a brief note, records the structure of the 
stomach in Plotus melanogaster. His account is confirmatory 
of that of the late W. A. Forbes, who has described this 
species (P. Z. S. 1882, p. 208), and whose memoir has ap¬ 
parently escaped the attention of M. Cazin.
