Immature specimens of TTdlothrir ha r rot! resemlile in color the adult 
females, but the feathers of the upper surface are more or less mar- 
gined with rusty, this persisting' longest on the head. 
Confined to the western side. These birds fly very rapidly and are somewhat difl[i- 
cult to shoot. Local name, "Angel quinde." 
FLORICOLA ALBICRISSA (Gould). 
Heliomaster <ilhl(yrism. Gould, Proe. Zool. Soc. Lond., 1871, p. 504. 
Flnricold alhicrisfiii'EijJAOT, Classif. Synop. Troeh., 1879, p. 83. 
Four specimens from Nanegal, west Ecuador. There is considerable 
individual variation in the color of the crown and throat, in some cases 
these parts being exactly like the same in Floricola superba, thus 
obliterating the specific diti'erences based thereon. The plain graj^ish 
white crissum will, however, alwa^^s serve to distinguish the present 
species. 
MYRTIS FANNY (Lesson). 
Orn'ismya fanny Lesson, Am. Sci. Nat., 2d ser., IX, 1838, p. 170. 
Myrtls frniny Cabaxis and Heine, Mus. Hein., Ill, 1860, i*. 59. 
Thirty specimens, from Chillo and Chota valleys, Ecuador. There 
is considerable variation in the amount of rufous on the lower surface 
in dili'erent examples, but this is apparently not to be correlated with 
locality. Immature males resemble the females. Contrary to the 
statement of Hartert,^ ])irds from Ecuador seem to average slightly 
larger than those from Peru, but there is no other observable 
difference. 
Common in parts of the Chillo Valley in Jannary. They feed chiefly on the flowers 
of the giant aloes, bnt we occasionally shot them about the guava flowers. Only 
one female was oljtained out of a series of .30. Local name, "Prelado" — prelate. 
MYRMIA MICRURA (Gould). 
Calothorax micrums Gould, Proc. Zool. Soc. Loud., 1853, p. 109.

p. 113. 
A single adult male from Santo Domingo, west Ecuador, taken in 
October, 1898, is the only specimen in the collection. This adds the 
species to the fauna of Ecuador, extending its range at least 300 miles, 
but this specimen seems to be typical, at least in so far as it is possible 
to judge from descriptions. 
A single specimen killed at Santo Domingo at dusk. Our attention was attracted 
to it by seeing it drive all other hummingbirds, large or small, away from the orange 
tree on which it was feeding. Being so small they are very difficult to shoot, as they 
seldom settle for an instant. Local name, " Quinde mosca" — fly hummingl)ird.
