134 DENTIROS TRES—DIA MOND-BIRD 
(Zoologist, p. 8692). It is considerably smaller than the ordinary 
Crane, G. communis, and has a long tuft of white feathers reaching 
backward behind each eye, while the black plumes of its breast and 
the grey inner secondaries are greatly elongated—the last especially. 
DENTIROSTRES, a group of Birds discriminated by Duméril 
in 1806 (Zool. Analyt. p. 41), composed of the genera (as then re- 
garded) Buceros (HORNBILL), MJomotus (Mormor), and Phytotoma 
(PLANT-CUTTER), as having their bills scored with at least three 
notches (dentelwres); but in 1817 used in a wholly different sense by 
Cuvier (2eegn. Animal, p. 336), so as to contain Laniidx, Tanagride, 
Muscicapide, Ampelidx | = Cotingidx]|, Edolius, Turdidx, Pyrrhocoraa, 
Oriolidx, Myiothera, Cinclus, Philedon, Gracula, Menura, Pipra, and 
Motacilla ; and subsequently adopted with more or less modification 
by a great number of systematists. 
DERTRUM, the hook of the BILt. 
DESMODACTYLI, the name proposed by Forbes (Proc. Zool. 
Soc. 1880, p. 390) for a group of PASSERES, consisting of the Huryle- 
midx (BROADBILL). 
DESMOGNATH A, Prof. Huxley’s third Suborder of CARINATA, 
composed of seven groups — CHENOMORPHA, AMPHIMORPH#, 
PELARGOMORPHA, DYSPOROMORPHA AETOMORPH, PSITTACOMOR- 
PHA, and CoccyGOMORPHA—1in all of which the vomer is often 
abortive or so small as to disappear; but, when existing, it is 
slender, and tapers anteriorly to a point, while the maxillo-palatals 
are united (whence the name of the Suborder) across the middle 
line, either directly or by the ossification of the nasal septum, and 
the posterior ends of the palatals and anterior of the pterygoids 
articulate directly with the rostrum. Moreover, the lower larynx 
in these birds is never formed on the plan of the PAssErEs. It 
may be observed that nothing approaching to this association of 
the groups above named had ever before been proposed by any 
taxonomer (Proc. Zool. Soc. 1867, pp. 435-448, 460-466). 
_ DEVIL-BIRD, a name applied by the English in Ceylon to a 
species of OWL, Stria or Syrnium indrani, as well as to a GOATSUCKER, 
Caprimulgus kelaartt (Legge, Bb. Ceyl. pp. 155, 337). 
DEVILING, a common local name for the SwIFT. 
DHYAL or DIAL-BIRD, see DAYAL. 
DIAMOND-BIRD, the name bestowed in Australia on the mem- 
bers of the genus Pardalotus founded in 1816 
by Vieillot (Analyse, p. 31), with Pipra punctata 
of Latham as its type, for which in our present 
ignorance it is hard to find a place. Gould 
DiaMONnD-BIRD. (Handb. B. Austral. i. p. 156) put it with a
