Show 1867.] THE BIRDS O F E A S T E R N P E R U . 755 the Cayenne bird principally in its smaller size and darker uropygiai band. The females seem also different from those of the typical form, being of a brighter ochreous behind, and having the yellow circlet round the eye much less defined-in some specimens hardly apparent. Specimen c of Tachyphonus sui'inamus (from Guia) of Sclater's collection (Cat. A. B. p. 85) also belongs to this form. (42.) CLYPICTERUS OSERYI (Deville). Cassicus oseryi, Deville, Rev. Zool. 1849, p. 57; Des Murs, Zool. Voy. Casteln. p. 66, pl. 18. f. 3. Clypicterus oseryi, Bp. Consp. i. p. 426. One example of this fine species, not quite adult, from Xeberos. It is the first time we have met with it. (47.) SCLERURUS MEXICANUS, Sclater. See our observations on this species (antea, p. 574). It is interesting to meet with a second southern specimen, confirming our views there expressed. (53.) XENOPS APPROXIMANS, Pelzeln, Sitz. Ak. Wien, xxxiv. p. 113 (1859). Two examples of this form from Chyavetas, agreeing with one of Natterer's typical skins of this species in Sclater's collection. (54.) DENDROCOLAPTES RADIOLATUS, Sclater, MS. .? One example from Yurimaguas of a species in Sclater's collection allied to D. cayennensis and D. sancti-thomee of Central Ameri i. It may be characterized as follows :- Similis D. cayennensi, sed major, supra et subtus omnino fasciolis nigris distincte transradiolatus : alis et cauda ferrugineo-rufis, alarum tectricibus nigro transradiatis : rostro pallide corneo; pedibus fuscis : long, tota 12*5, alee 5*0, caudee 4*7, rostri a rictu 1'9 poll. Angl. Hab. in Peruv. orient. Yurimaguas (Bartlett). In D. sancti-thomee the lower back is rufous, unbarred; the radiations are much closer, the bill is smaller and nearly black, and the whole bird is smaller. A fourth species of this group (the only other with which we are acquainted) is the newly described D. concolor, Pelzeln. (55.) DENDRORNIS OCELLATA, Spix. Dendrocolaptes ocellatus, Spix, Av. Bras. i. p. 88, t. 91. f. 1. A single specimen agrees with a skin (determined by Pelzeln to belong to Spix's species) in Sclater's collection, collected by Natterer on the Rio Negro. (57.) THAMNOPHILUS FULIGINOSUS, Gould. A female, probably of this species, from Xeberos. A somewhat similar specimen is in the British Museum. |
