DEFINITIONS

BATRACHOSTOMUS
(Podargidae; Ϯ Large Frogmouth B. auritus) Gr. βατραχος batrakhos  frog; στομα stoma, στοματος stomatos  mouth. "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. [17] and text. Type, by monotypy, Podargus auritus J. E. Gray." (Peters, 1940, IV, p. 177).
Var. Batraeostomus.
Synon. Bombycistoma, Otothrix.

POLIOLOPHUS
(Pycnonotidae; Ϯ Yellow-wattled Bulbul P. urostictus) Gr. πολιος polios  grey; λοφος lophos  crest; "POLIOLOPHUS, gen. n.    76. POLIOLOPHUS UROSTICTUS. — Ixus? urostictus, Walden, t. c., p. 191, pl. xxxii. fig. 2.   ...   The combination of an eye-wattle and a crest seem to me to indicate that this bird should be placed in a distinct genus from Pycnonotus or Otocompsa; and I therefore propose the name of Poliolophus.  The colouring of the bird is very badly rendered in the plate accompanying Lord Walden's paper — the greyish crest not being defined, and the eye-wattle entirely omitted." (Sharpe 1877).
Var. Poliophilus.
