List of the Birds sent home by Mr. Joseph Thomson from the River Rovuma, East Africa. By Captain G. E. SHELLEY. [Eeceived February 25, 1882.] (Plate XVI.) Mr. Thomson is well known as one of the most successful East- African explorers. On him devolved the task of carrying through the expedition in which Mr. Keith Johnston lost his life ; and no praise can be too strong for the manner in which he fulfilled his mission. Like all successful African travellers, he has again returned to the Dark country, this time to explore the river Rovuma and to report on the value of the coal-fields said to exist in that valley ; aud an interesting account of his journey has been given by himself (Proc. R. Geogr. Soc. 1882, p. 65). The Rovuma runs from the south-west into the sea at 10° 30' S. lat.; and Mr. Thomson explored this valley to nearly 37° E. long. During this journey the present collection of birds was made, whereby two interesting new species are added to the African Avifauna. 1. Astur tachiro (Baud.). 2. Falco minor, Bp. 3. F. dickersoni, Sclat. 4. Coracias caudata, Linn. 5. Halcyon orientalis, Peters. 6. Merops dresseri, sp. n. 7. Melittophagus budockoides (Smith). 8. M. pusillus (Mull.). 9.
