134 ' DENTIROSTRES— DIAMOND-BIRD 



(Zoologist, p. 8692). It is considerably smaller than the ordinary 

 Crane, G. cowmnnis, and has a long tuft of white feathers reaching 

 backward behind each eye, while the })lack plumes of its breast and 

 the grey inner secondaries are greatly elongated — the last especially. 



DENTIROSTRES, a group of Birds discriminated by Dumeril 

 in 1806 (Zool. Anulijt. p. 41), composed of the genera (as then re- 

 garded) Buceros (Hornbill), Momotus (Motmot), and PJii/totoma 

 (Plant-gutter), as having their bills scored with at least three 

 notches (dentelures) ; but in 1817 used in a Avholly different sense by 

 Cuvier (Begn. Animal, p. 336), so as to contain Laniulx, Tanagridx, 

 Muscicajndai, Ampelidai [ = Cotingklfe], EdoUvs, Turdidge, Pyrrhocorax, 

 Oriolidm, Mi/iothera, Cinclus, Fhikdon, Gracida, ilfenura, Fipra, and 

 MotariUa ; and subsequently adopted with more or less modification 

 by a great number of systematists. 



DERTRUM, the hook of the Bill. 



DESMODACTYLI, the name proposed by Forbes {Proc. Zool. 

 Soc. 1880, p. 390) for a group of Passeres, consisting oi the Euryliv- 

 mida} (Broadbill). 



DESMOGNATH JE, Prof. Huxley's third Suborder of Carinat^, 

 composed of seven groups — Chenomorph^, Amphimorph^, 

 Pelargomorph^, Dysporomorph.e Aetomorph^, Psittacomor- 

 PH^, and CoccYGOMORPH^ — in 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, Avhile 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

 ignorance it is hard to find a place. Gould
