314 TROCHILIDA. 
parts grown bird from Sierra de Victoria was shot by Mr. Richardson in April, so that 
the nesting-time in that district would commence in March or the end of February. 
But the nesting-season probably extends over a considerable period, for de Oca says 
he once found a nest in December, though the usual nesting-time in the valley of 
Mexico, where the bird is more common than at Jalapa, is in July and August. 
According to Villada it feeds from the flowers of Cacti and Agave, and also from those 
of Bouvardia and Salvia ??. 
Mr. Richardson’s specimens were all shot at Matagalpa between June and October. 
In Lower California an allied species occurs in PB. xantusi, distinguished by its 
cinnamon abdomen and chestnut tail. ‘This bird has not yet been detected on the 
eastern side of the Gulf of California.

Of this genus, remarkable for the very singular shape of the bill, only one species 
occurs within our limits, ranging from the western part of the State of Panama to Costa 
Rica. This bird has two close allies—one in Colombia and the other in Western 
Ecuador. Another species (L. condaminit) is very distinct, and is only found on the 
eastern slopes of the Andes of Ecuador and Peru. utoweres is closely allied to 
Phaethornis, but may at once be distinguished by the bill, which is abruptly curved to 
a third of a circle.
