comes next to P. macei. M. Oustalet also gives many notes 
on the birds of New Caledonia and the New Hebrides. 
45. Oustalet on the Birds of Gaboon. 
[Catalogue Méthodique des Oiseaux recueillis par M. Marche dans son 
voyage sur l’Ogdoué avec description d’espéces nouvelles, par M. E. Ous- 
talet. Nouv. Arch. Mus. sér. 2, tome ii. p. 53. ] 
An important memoir on the birds collected by M. Marche 
during his recent expedition up the Ogové, in company with 
MM. Savorgnan de Brazza and Dr. Ballay. To the list are 
added such species of the colony of Gaboon as were previously 
represented in the Paris Museum by unquestionably authenti- 
cated specimens. This makes a total of 152. But if we add 
the species enumerated by Cassin in his papers upon Du 
Chaillu’s collections not represented at Paris, the whole 
avifauna of this district would appear to embrace at least 
300 species. 
The new species now described are Dendropicus sharpiu and 
Dicrurus sharpii. Figures are given of Sigmodus rufiventris, 
Txonotus guttatus, and Querquedula hartlaubt. 
46. Oustalet on Birds from the Loss Islands. 
[Note sur une petite collection d’oiseaux provenant des iles Loss, Afrique 
Occidentale. Ibid. p. 149. ] 
The Loss Islands lie off Sierra Leone, on the West-African 
coast. The collection received contained examples of fifteen 
mostly well-known species; but amongst them was the fine 
new Glossy Starling, Coccycolius iris, previously described 
(cf. Ibis, 1879, p. 475), but now figured.
