Show 1875.] ON N E W SPECIES OF SOUTH-AMERICAN BIRDS. 37 3. Descriptions of some new Species of South-American Birds. By P. L. SCLATER, M.A., Ph.D., F.R.S., and OSBERT SALVIN, M.A., F.R.S. [Received December 21, 1874.] (Plate VI.) 1. MICROCERCULUS SQUAMULATUS, sp. nov. (Plate VI.) Supra fuscus unicolor: subtus fere concolor, gutture albo, pectore et ventre medio albis, plumis fusco undulatis : subalaribus et remigum marginibus internis fuscescenti-cineraceis: rostro corneo; pedibus fuscis: long tota 4'2, alee 2*5, caudce 0*8, rostri a rictu 1. Hab. Venezuela, San Cristobal (Goering). Obs. Aff. M. bamblce, sed fascia alari alba nulla, et gutture albo necnon ventre squamulato diversus. A single skin of this apparently new Microcerculus occurs in Goering's last collection. It was obtained at San Cristobal in the Venezuelan province of Tachira, on the frontiers of Columbia. In form it seems to be nearest to M. bambla, but in plumage is perhaps rather more likely to be confounded with M. marginatus, than which, however, it has much less white below and has a longer bill. The discovery of this bird increases the number of known species of the genus Microcerculus to six *. M. squamulatus should stand next to M. bambla. 2. AUTOMOLUS STRIATICEPS, sp. nov. Terreno-brunneus, pileo nigricante; hoc cum dorso superiore fiavido longitudinaliter lineato ; alis immaculatis : uropygio et cauda tota rubiginosa-rufis: subtus fulvus, lateraliter obscurior, gutturis plumis fusco marginatis equasi squamatis : subalaribus et remigum marginibus internis fiavicanti-fulvis : rostro corneo, pedibus fuscis: long, tota 7, alee 3*5, caudee rectr. med. 3*5, ext. 2*25. Hab. Columbia int. et Peruv. A Bogota skin of this species has been in Sclater's collection for some time, having been purchased from a London dealer. Its bill is not quite perfect; and the general similarity of its plumage to that of Anabazenops subalaris caused it to be passed over when our 'Nomenclator' was written. When M. Taczanowski brought M . Jelski's Peruvian collections to compare with Sclater's series a second, perfect example of this bird was found, which had been obtained by Jelski at Chilpes in Central Peru; and M . Taczanowski has inserted it in his list under Sclater's M S . name f. A. striaticeps is, in fact, a very distinct species, belonging to the more strongly formed Automoli allied to A. cervinigularis, A. ochro-lesmus, &c, and is distinguishable from all species known to us by * For a list of the other species, see Scl. et Salv.
