Durnford found this fine Woodpecker "resident and common" to the north of Buenos Ayres, and on the banks of the Paraná. It is likewise met with in the more northern provinces of the Republic. White obtained specimens in Catamarca and Salta, and Durnford, during his last expedition, in the latter locality. Mr. Barrows speaks of its occurrence in Entrerios as follows:-- "A part of the last week in April 1880 was spent in a considerable tract of forest bordering a stream known as the 'Arroyo Gualeguaychú' at a point about twenty miles west of Concepcion. The wood borders the stream to a depth of a mile or more on each side and stretches up and down stream indefinitely. It had suffered comparatively little from the axe of the charcoal-burner, and many birds, not elsewhere seen, were met with here. Among these was the present beautiful Woodpecker, of which, however, only a single pair was observed, and the male alone taken. It is said to occur sparingly in all the large forests." 249. CAMPEPHILUS SCHULZI (Cab.). (SCHULZ'S WOODPECKER.) +Phloeotomus schulzi+, _Cab. Journ. f. Orn._ 1883, p. 102. +Dryocopus atriventris+, _Burm. La-Plata Reise_, ii. p. 444 (?). Under this title Dr. Cabanis has shortly described a Woodpecker procured in Central Argentina by Herr Schulz. It is a diminutive form of _C. pileatus_ of North America; and differs from that species in colour only in the following points:--The red crest is comparatively more developed and more pointed; the general colour is more intensely black; the white markings of _C. pileatus_ are present in _C. schulzi_, but the extent of the white on the underside of the wings and on the carpal joint is much less in the latter species. No dimensions are given. Dr. Cabanis is of opinion that the bird from Mendoza described by Dr. Burmeister as the young of _C. boiæi_ is referable to this new species. 250. DRYOCOPUS ERYTHROPS (Val.). (RED-FACED WOODPECKER.) +Dryocopus erythrops+, _Scl. et Salv. Nomencl._ p. 99; _White, P. Z. S._ 1882, p. 617 (Misiones). _Description._--Above black; crested head scarlet; broad line from front beneath the eye and down the neck white; malar patch scarlet: beneath, throat white, with black striations; breast black; belly white, transversely barred with black; under surface of wings white; bill plumbeous; feet black: whole length 13·0 inches, wing 7·5, tail 5·0. _Female_ similar, but anterior half of head black, and no scarlet malar patch. _Hab._ Brazil. White states that he "observed" a few specimens of this Brazilian species in the dense forests of Misiones; but its occurrence so far south requires confirmation. A more likely species of this genus to occur there would be _D. lineatus_, which has been found in Paraguay (_cf._ Berlepsch, J. f. O. 1887, p. 20). 251. PICUS MIXTUS, Bodd. (VARIED WOODPECKER.)
