The same muy be said of C. nwrgai-etlixe, a form which inhabits the coast 

 mountains from L'aracas to Pnerto Cabcllo. ''. tmnujarethiie dilVors only from kingi 

 in its less deep green colour of the upper parts, and often of the under surface as 

 well, and generally very much more green colour of the central rectrices. There 

 are, however, specimens from Bogota which cannot be distinguished except for the 

 darker cokwr of their ni>per surface. Tlie /('/«'(//' .s are alike. This form is there- 

 fore only a subspecies, and has been quoted with trinomials by Count von Berlepsch, 

 although its home is far more distant from that of /.-i/'i/i than that oi i-andiitu, which 

 lives between liim/i and margarethne. 



C. Iihtgi hhigi, as I call tlie I?ogut:i iurm witli the outer elongated rectrices blue, 

 varies considerably in the amount of green and purple on the central rectrices, these 

 being as purplish blue as in the outer pair, or about as green as iu C. kingi 

 margarethne; but these various varieties of ('. Iiingi Itingi run completely into each 

 other and probably come from the same countries. The exact range of C. kingi 

 kingi is not yet known, but it certainly lives iu the environs of Bogota. 



The status of the genus is thus, .after removal o( grixeiventris, as follows: — 



1. C. kingi kingi (Less.). Andes of Colombia. Very common in Bogota 

 collections. Exact range not known, but found near Bogota frmn i^OOd to 

 9000 feet. 



:,'. C. kingi emmae Berlp. Andes of Colombia. Mncli rarer in Bogota 

 collections, and only more recently found in numbers. Probably inhabiting the 

 nortlieru portions of the slopes ascending from the Magdalena River to the eastern 

 range of the Andes. 



3. C. kingi mocoa (Del. & Bourc.j. Eastern slopes of Andes in the southern- 

 most parts of Colombia and Ecuador. 



4. C. kingi smaragdina (Gould). Bolivia and soutliornmost parts of Peru. 



5. €. kingi margarethae (Heine). Coast mountain-ranges of Venezuela 

 (Caracas, Cumbre de Valencia). 



0. C. kingi caudala Berlp. Andes of Venezuela. 



7. C. coelestis (Gould). South-Western Colombia and Ecuador. 



8. C . berlepschi 'Rnri. Hills of Cumana, Venezuela. 



The Genus FLORISUGA auct. 



I agree with E. Simon that this genus is best placed near Eupetomena. The 

 slightly curved bill is similar. .'■'. iiidVuora, the " ty])e " of the genus, is one of 

 the oldest and best known Hnmming-Birds. Linne, in 17.i8 (tenth edition), named 

 it Trochilus niellimrus. From the synonymy in the Cat. Birds Brit. Mus. XVI. 

 p. ;iiJ9, it would seem that Linne, on the same i)age where he enumerated the bird 

 under the same name in 1706 (twelfth edition), called it also Trochiliis Jinibriatits ; 

 but he did no such thing, this name being created more than twenty years later 

 by Gmelin. Salvin must have copied the mistake from Elliot. Salvin also 

 describes the male as having the middle rectrices bluish green, but they are all 

 white, and what lie thought to be the middle rectrices are the two longest upper 

 tail-coverts. This peculiar character, viz. the elongation of the tail-coverts and 

 their assimilation in shape to the rectrices, is very remarkable, and, in addition 

 to the difference of the plumage of the sexes, only found in F. mellioora, but not in 

 F. fiisca. It is therefore only consistent with the universal custom of dividing 

 the Trochilidae into many genera to accept the genus Melanotrochilus, as diftering
