THE BIRDS OF AUSTRALIA. 
The other species, fulgidus Gould, has the genus name Caridonax 
I.)roposed by Cabanis and Heine available, and this should be used. In 
addition to its distinct coloration, the tail is longer and more graduated, 
the bill is noticeably less keeled and the wing-formula differs. The first 
primary is little less than the secondaries and equal to the eighth 
primary, the fourth longest, the third equal to the fifth, the second equal 
to the sixth. 
The genus Haley on^ as catalogued in the British Museum Catalogue, 
would then be split up into many, as follows : — 
Entomothera coromanda (Latham) must be altogether removed from the 
family and placed alongside Ceyco'psis in the family Alcedinidee ; I suggest 
a subfamily Ceycince for the “ red Ceyces ” whether three or four-toed, and 
further anticipate it may later have family rank. 
Nutchera is proposed for Halcyon hadia Verreaux alone. Its exact 
relationships are unknown, and it lacks the white basal primary bar found 
throughout the succeeding five series. 
Plesialcyon is introduced for Alcedo smyrnensis Linne, Entomohia, pro- 
posed by Cabanis and Heine, being preoccupied. Additional species are 
Alcedo gularis Kuhl and Alcedo cyanoventris Vieillot. Though the latter is 
superficially different, the plumage changes prove it to be a true relative 
of smyrnensis. 
Cecilia is proposed for Alcedo pileata Boddaert. This was included by 
Cabanis and Heine in Entomobia but, though having a superficial resemblance 
to that genus, shows structural differences as well as those of colour that 
demand separation. 
Chelicutia should be utihsed for Alcedo chelicuti Linne, and Chelicutona 
is added for Alcedo albiventris Scopofi and here is admitted Alcedo 
leucocephala Muller = semicceruleus. Catalogue of Birds. The former genus 
is well characterised by coloration, size and structure, while the latter 
seems a derivative which has altered in coloration, size and structure, so that 
it approaches the next in these details, but cannot be regarded as congeneric. 
Halcyon will be preserved for its type species senegalensis Linn., the 
species irroratus, Catalogue of Birds = senegaloides recte being included as 
well as the torquatus series, which are regarded as being subgenericaUy 
separable with the name Halcyonopa. 
In the Catalogue of the Birds in the British Museum, Vol. XVII., p. 249, the 
saurophagus group follows, but this I regard as a subgenus of Sauropatis, to 
which I have given the name Leucalcyon. 
The next series is my genera Lazulena and Dilazula. Then followed 
Halcyon pyrrhopygius, the type of Cyanalcyon. Interposed between this
