Mr. D. G. Elliot on the Trochilidse. 
(c) Intermediate between tlie Bua bird and the collarless variety found 
on Taviuni. Found on Koro only. 
(d) I do not think this is a good species ; I include it on the authority 
of Drs. Finsch and Hartlaub, with their mark of f. 
( e ) Included on the above authority. They give no special locality. 
(/) Ditto. It is said to have been found in Sandalwood Bay ; but none 
of my collectors have seen it, and I doubt the statement. 
(g) A fine new species, entirely green, with yellowish legs and bill, 
just discovered by Herr Godeffroy’s collector. 
(Ji) Discovered by Mr. Ramsay’s collector, therefore not named. 
(i) Ditto. I know not to what genus to refer this bird. 
(J) I originally placed this bird, provisionally, in the genus Lolage , not 
having any works of reference at hand for consultation. It certainly does 
not belong there, and is nearer Myiolestes. [A typical Myiolestes, fide 
Finsch, P. Z. S. 1876, p. 20.—Ed.] 
( k ) Discovered by Mr. Ramsay’s collector. The giant of the genus. 
(l) The letter U after this name and others stands for a Ubique,” the 
species being generally distributed on our seaboard and in our seas. 
(m) Included on the authority of Drs. Finsch and Hartlaub, who give, 
on G. R. Gray’s authority, the locality Ngau Island. 
( n ) I did not see this bird, which was picked up not far from Mr. 
Kleinschmidt’s house, and taken to him ; he assures me it was a genuine 
Zctrus.

scribed by Dr. Finsch (P. Z. S. 1876, p. 19) as Drymochcera badiceps. —Ed.]

XXXIX .—Notes on the Trochilidae. The Genera Heliothrix, 
Calliphlox, Catharma, and Petasophora. By D. G. Elliot, 
F.B.S.E. &c. 
Genus Heliothrix. 
The members of the genus Heliothrix are possessed of 
graceful form and a plumage of a pleasing contrast of green 
and white. They have long tails, the female^s being longer 
than that of the adult male. The three species are dis¬ 
tributed generally over Central and South America, not, how¬ 
ever going south of Brazil on the east coast, nor Peru on the 
west. In reviewing the geographical distribution of the 
species, we see that Guatemala is the most northern country 
which any of them inhabit; and here is found H. barroti , 
which goes through Central America, Columbia, into Ecuador,
