PREFACE. 



The present Volume contains an account of the remaining families 

 of the suborder Coracice as understood by Seebohm, as well as of 

 the Halcyones, Bucerotes, and Trogones. 



The numbers of the species of the nine families treated of, and of 

 the specimens at present in the Collection, are as follows : — 



Species. Types. Specimens. 



Leptosomatidte 2 . . 16 



Coraciidae 25 7 663 



Meropidie 36 5 692 



Alcedinidaj 183 57 3679 



Momotidae 21 7 347 



Todids 5 1 41 



ColiidfB 10 2 104 



Bucerotidae 68 12 1079 



Trogonidse 47 19 1283 



397 110 7904 



Of these 397 species, only 16 are wanting to the collection of the 

 Museum, and more than one-fourth of them are represented by the 

 types ; but besides these there are 30 other typical specimens 

 now considered identical with previously named species. 



In many cases the series of specimens is sufficiently complete 

 to illustrate the whole geographical range of a species — a result 

 chiefly due to the accession of the great faunistic collections referred
