The above list of synonyms are given on the authority of Dr. Cabanis : it is just possible that they may refer 

 to the female of my P. Episcopus ; but I fear that this cannot at present be satisfactorily determined.

Subfamily IL TROCHILIN.E. 



I commence the second volume with the Campylopteri, a group of Humming-Birds distinguished by their great 

 size, by the diversity of their colouring, and by the broad, dilated shafts of the first three primaries or quill-feathers 

 of the males. The members of this group are spread over nearly the whole of the temperate regions of America, 

 from Mexico to the equator, including Brazil, Guiana, Venezuela, and some of the West Indian Islands. 



This section of the Trochilidse comprises several very distinct forms : — one remarkable for a deeply forked tail, 

 for the rich blue colouring of the body, and for the similarity in the outward appearance of the sexes ; another for 

 having the tail cuneate ; while a third, comprising six or seven species, is distinguished by a very ample and rounded 

 tail. It is for the last form alone that I have retained the generic appellation of Campy lopter us, applying that of 

 Eupetomena to the deeply forked-tailed bird macroura, Sphenoproctus to the cuneate-tailed Pampa, and Phaochroa to 

 the Cuvieri and the allied Roberti, which may be considered as aberrant, the broad shafts of the primaries (the 

 principal characteristic of the group) being but slightly developed. These birds lead on to Aphantochroa.
