Rhegmatorhina^Ϯ gymnops, sp. nov.  ...  ^Ϯ Rhegmatorhina, genus novem Formicariidarum (ῥηγμα = fissura; ῥις = nasus).   GEN. CHAR.—Similar to Phlogopsis but differing very materially in the form of the nostril, which consists of a narrow longitudinal slit-like opening, overhung by a broad, rather thickened, membrane or operculum.  Orbital region entirely naked, the bare space broadly oval, slightly pointed anteriorly (about midway of the lores), but rounded posteriorly.  Feathers of pileum lengthened, narrow, decurved, rather stiff, and distinctly individualized, forming a loose crest when erected; those of the forehad and lores (anterior half) shorter, straighter, and more dense.  Tail more than two-thirds as long as wing, slightly rounded, the feathers broad and rounded.  Wing about three times as long as tarsus, much rounded (fifth and sixth quills longest).  Tarsus more than twice as long as bill from nostril, booted.  Colors plain.   Type, R. gymnops, sp. nov.” (Ridgway 1888).

• (Sturnidae; syn. Sarcops † Coleto S. calvus) "LES GOULINS. (GYMNOPS. Cuv.)  Ont le même bec fort que les loriots, les narines rondes, sans écailles, et sans entourage membraneux, et une grande partie de la tête dénuée de plumes.

Dans ces derniers, la langue est un pinceau comme dans les philédons.  ...  (1) Le goulin gris (gracula calva, Gm.), enl. 200: - le Goulin vert (mino Dumontii, Less.), Voy. de Duperrey, pl. xxv; - le Goulin olive (gracula cyanotis, Lath.; merops cyanotis, Sh.)   (2) Le corbicalao, Vaill., Ois. d'Am. et des Indes, pl. xxiv (merops corniculatus, Lath. et Sh.), et une espèce voisine, dont le tubercule, plus grand, se dirige vers le front (Mer. monachus, Lath.). Ces deux oiseaux de la Nouvelle-Hollande ne sont ni des calaos ni des guêpiers, car ils n'ont pas les doigts externes plus réunis que les passereaux les plus ordinaires" (Cuvier 1829); "Gymnops Cuvier, 1829, Règne Animal, nouvelle éd., I, p. 381.  Type, by monotypy, Gracula calva Linnaeus, 1766."
