"Rostrum capite latius ad apicem abrupte acuminatum deflexum, maxilla inverse spatulæformis, culmine carinato" (Horsfield 1821); "Its characters are like those of Podargus Javanensis of Dr Horsfield, having many long loose feathers proceeding horizontally from the root of the upper mandible, which gives the bird a singular and grotesque appearance" (J. Gray 1829); "Genus BATRACHOSTOMUS, Gould.  CHARACTERES GENERICI. Rostrum latius, ac magis depressum quam in genere Podargus dicto, (cui generi hoc approximat) culmine minus carinato.  Nares tubulares, transversim positæ et penicillis tectæ.  Oculi superne cute nuda late marginati, et cristulis plumosis, altera superciliari, altera infra-oculari, postice spectantibus instructi.  Alæ quam in Podargo longiores, remigibus quarto, quinto, sexto et septimo longissimis et inter se fere æqualibus.  Cauda mediocris et rotundata.  Tarsi digitique non tantum breviores sed debiliores quam in Podargo; tarsi antice per dimidium plumosi.    BATRACHOSTOMUS AURITUS.    ...   It is a native of Sumatra, Malacca, &c.  ...  but nothing whatever is known as to its habits or economy."(Gould 1838); "Batrachostomus Gould, Icones Av., pt. 2, 1838, pl.
