As, however, the term hyperythrus is only applicable to one sex, it will be more convenient to use the more recent name. A pair of this species are in the present collection, procured on the same day, and with the sex of each marked. 55. TYRANNISCUS GRACILIPES, sp. nov. Tyranniscus gracilipes, Sclater, M S . Olivaceus, pileo obscure cinereo : loris albidis : alis nigris, secundariis et tectricibus flavo marginatis: cauda nigricante, olivaceo extus marginata : subtus pallide flavus : rostro nigricante, pedibus plumbeis : long, tota 4*3, alee 2, caudce 1*9, tarsi *55. Hab. in Peruv. orient. Pebas (Hauxwell). Three specimens of this species agree with an indifferent skin in Sclater's collection (No. 1317 of his 'American Catalogue'), said to he from Venezuela. Two of them are somewhat shorter in the wing than the described specimen, which is marked male. The nearest described species seems to be T. parvus, Lawrence (Ibis, 1862, p. 12), which is of about the same size, but has the throat and breast white. 65. MUSCIVORA CASTELNAUDI. Onychorhynchus castelnaudi, Deville, R. Z. 1849, p. 57. A single specimen of this bird is in the collection, but does uot appear quite adult. It presents some of the distinctive characters pointed out by M . Deville ; but we should prefer to see further specimens before guaranteeing the species as distinct from vif. regia. 128. PORZANA FASCIATA, sp. nov. Corethrura, sp., Scl. & Salv. P. Z. S. 1866, p. 200. Castanea: dorso et alis extus brunnescenti-olivaceis : ventre toto cum hypochondriis et subalaribus nigro transfasciatis: rostro nigro, pedibus rubellis : long, tota 6*8, alee 3*8, caudee *9, tarsi 1*6, rostri a rictu *9. Hab. Peruvia orient. Pebas et Chamicurros (Hauxwell); fl. Ucayali (Bartlett). Obs. Similis P. castaneee, Cuv., sed ventre fasciato diversa. A single specimen of this Rail was in Mr. Bartlett's Ucayali collection and is now in the British Museum. In the same collection is a second example, obtained some years ago by Mr. Hauxwell at Chamicurros. The species appears to be unnamed, but it is a very distinct one, and belongs to the group Rufirallus of Bonaparte. W e propose to o-ive a figure of it in a forthcoming number of our ** Exotic Ornithology.' |
