(Eurylaimidae; Ϯ Javan Broadbill E. javanicus) Gr. ευρυς eurus  broad; λαιμος laimos  throat; “Gen. 38. EURYLAIMUS.  Rostrum capite brevius, validum, depressum, basi latissimum, postice dilatato-ampliatum, margine angusto intracto.  Rictus amplissimus.  Maxilla culmine obsolete carinato apice abrupte adunco, emarginato, tomiis verticalibus.  Mandibula basi recta ad apicem maxilla congruenter curvata.  Nares basales, subrotundæ, apertæ, omnino nudæ.  Pedes congrui, gressorii.  Digiti compressi, medius fere longitudine tarsi, hallux robustus.  Alæ cauda breviores.  Rectrices 12.    The distinguishing characters of this genus are a broad, depressed, cuneated beak (passing backwards into a narrow incurved margin, which extends beneath the eyes and forms an excessively wide throat) and prominent, erect, vertical cutting edges (tomia), associated with gressorial feet.  In these characters, and also in the nakedness of the nostrils, it differs essentially from Todus platyrhynchos, which is arranged among the Dentirostres (Sylviadæ Leach) by M. Cuvier.  It resembles Todus viridis (the only species of the genus known at present, Temm.) in the gressorial feet, but differs essentially from it in the form of the bill, disposition of the nares, &c.     Spec. 1. Eurylaimus Javanicus mihi.” (Horsfield 1821); "Eurylaimus Horsfield, Trans. Linn. Soc. London, 13, pt. 1, 1821, p. 170. Type, by monotypy, Eurylaimus javanicus Horsfield."
