DEFINITIONS

AULACORHYNCHUS
(Ramphastidae; Ϯ Groove-billed Toucanet A. sulcatus) Gr. αυλαξ aulax, αυλακος aulakos  furrow; ῥυγχος rhunkhos  bill; "A specimen was placed on the table of a Toucan, apparently hitherto undescribed  ...  By its comparatively short bill, which is furrowed on the sides, and broad and flattened on the culmen, with the base of the under mandible extending obliquely beyond the line of the eye; by the shortness and roundness of its wings, of which the fourth quill-feather is the longest, the fifth, sixth, and seventh being nearly of the same length; and by the comparative shortness of the tail, which is less decidedly graduated  than in the typical Pteroglossi; this bird agrees with the species described in Mr. Gould's 'Monograph of the Ramphastidæ,' as the Pter. prasinus, Licht., and Pter. sulcatus, Swains. With those species Mr. Gould proposes to associate it in a group, to be designated, on account of the grooved bills of the Birds comprised in it, Aulacorhynchus.  From the other two species it is readily distinguishable by the white band nearly surrounding the base of its bill, and by the blood-red spot on the rump. The latter character affords the trivial name of the species, which may, for the present, be inserted in the account of the Toucans given by Mr. Gould at the Meeting of July 8, 1834, (page 78,) immediately before the Pter. prasinus, Licht.    PTER. HÆMATOPYGUS." (Gould 1835); "Aulacorhynchus Gould, Proc. Zool. Soc. London, pt. 2, 1834 (1835), p. 147. Type, by subsequent designation, A. sulcatus (Swains.) = Pteroglossus sulcatus Swainson. (G. R. Gray, List Gen. Bds., 1840, p. 50)." (Peters, 1948, VI, p. 70).
