These species, with others, are very probably a subgeneric group of 

 the typical genus Halcyon. 



At present we are acquainted with no other birds which are pro- 

 perly included in the genus Todiramphus, nor with any others that 

 have been assigned to it by authors. Specimens of all of the fourteen 

 species described above, are in the Museum of the Philadelphia Aca- 

 demy, and as stated in the preceding pages, this genus is also liberally 

 represented in the collection of the Expedition. For the use of very 

 fine specimens of various species, figured in the Atlas to the present 

 volume, we are indebted to the liberality of the gentlemen of the Aca- 

 demy. 



Availing ourselves of the present opportunity, we have had figured 

 for our Atlas, all species of this genus not previously represented in 

 the plates of authors, and whenever practicable, we have given all 

 stages of plumage of which we have specimens. For much the greater 

 part our figures satisfactorily represent the species intended, though 

 in a few instances we could have wished for greater success. The 

 coloring, however, which has been done under the immediate super- 

 vision of that accomplished colorist, Mrs. Lavinia Bowen, of Phila- 

 delphia, is unexceptionable.
