NO. 1258. COLLECTION OF ITTWMIXG BIRDS— OBERHOLSER. 3 1 '. I 
THALURANIA FANNYI ( Delattre and Bourcier). 
TrochUui^ fannyi Delattre and liornciEU, Rev. ZooL, 1846, p. 310. 
Thahiran'm fanny Bonaparte, Rev. Zool., 1854, p. 254. , 
Eleven .specimens, from ISanegal, (TUtilea, and Milligalli, west Ecua- 
dor. There is considerable difference in the shade of the abdomen in 
the different adult males, this ranoing- from a rich violet purple to deep 
blue with but a slight tinge of violet. The four adult females ar<: of 
unusual interest, for they prove beyond much doubt that the female 
of this species is, as supposed ])y Salvin.^ quite different from the same 
sex of Thahi/zcmia erij)hlh' in haxing the abdomen dull brownish slate 
color glossed with metallic green, instead of being like the rest of 
the under surface, dull grayish white. Mr. Tlartert's opinion' that 
this represents the plumage of only the vouug male seems not to be 
correct, as a young male in the present collection is apparently not 
distinguishable from the adult females. 
THALURANIA NIGROFASCIATA (Gould). 
Trocldhis ( ?) nigrofuseiata Ctoild, Prot'. Zcx)!. .Sue. Loud., 1846, p. 89. 
Tliolurania nigrofasciata Gould, Proe. Zool. Soc. Lond., 1852, p. 8. 
Three specimens, from Archidona, east Ecuador, April, 1899, 
seem not separable from Colombian examples. 
COLIBRI DELPHINAE (Lesson). 
Ornismya delphinac LessOx, Rev. ZooL, 1839, j). 44. 
Colibri delphinae Bonaparte, Congp. Avium, I, 1850, p. 09. 
Five specimens, from Mindo and Gualea. west Ecuador. These 
apparenth; differ in no essential respect from either Guatemala or 
Guiana examples. 
COLIBRI CYANOTUS (Bourcier and Mulsant). 
TrochUun cyanoins Bofrcier and Mclsant, Ann. Se. Phys. et Xat. Lyon, VI, 
1843, p. 41. 
Colibri cyanofis Bonaparte, C'onyp. Avium, I, 1850, p. 69. 
Three examples, from Baeza, east Ecuador. Seemingly identical 
with birds from Venezuela, the type locality; but evidently not fully 
adult, as there are traces of ochraceous edging to some of the feathers, 
and the lower tail-coverts are largely ochraceous. The kinship of this 
species to Colihri thcdassinvs of ^Mexico and Guatemala is evidenced 
l)y the strongh^ bluish tinge of the central abdomen in the Costa 
Kican race, Colihri cyanotiis cahanidis (Heine), but this does not appear 
to bridge the gap between tJinhissinu.'< and ci/anotiis sufficiently to 
render a trinomial necessaiy for the latter.
