266 Mr. 0. Salvin on the 



the otlier side. In the evening of the same day, I saw the old 

 one feeding it^ and went up to the tree ; but it started off with 

 increased vigour to an orange-tree, and tried at first to rest on 

 one of the fruit, but failing, found a more appropriate perch on 

 the edge of a leaf. I never saw it afterwards. 



The other young one flew on October 17th, two days later. 

 The proportion of males to females, of my Duenas skins, is as 

 five to three, while of those from Coban, as three to five. 



The seeds of the willow and bulrush are favourite materials 

 for the interior structure of the nest of T. henicura, while lichen 

 is freely used outside. 



13. SeLASPHORUS HELOISiE. 



Volcan de Fuego and " tierra caliente" N. of Coban. 



Two bu'ds were given to me by Don Vicente Constancia, who 

 had just received them from a place called Chimachoyo, near 

 Calderas in the Volcan de Fuego. Two specimens I have in my 

 collection from Coban were shot in the tierra caliente north of 

 that city. Hence it would appear that this, like many other 

 species of Humming-birds, is found in very difi'ereut climates. 



14. Tryph^na duponti. 



San Geronimo. December 10th. 



Don Vicente Constancia assures me that this species is found 

 near the city of Guatemala ; otherwise this is the only locality I 

 have been able to discover, as yet, where it occurs. 



Following the course of the river of San Geronimo up its bed 

 to a distance of about half a league from the village, you come 

 upon a small patch of forest with here and there open spots 

 covered with Salvia. Here it was that this bird was shot by a 

 boy, who told me there were plenty ; however, on visiting the 

 place soon after, I was not successful in obtaining more speci- 

 mens, nor was I fortunate enough to see one. 



15. Trochilus colubris. 

 Duenas and Coban. 



The 24th of August was the day on whicli I first met with 

 this little wanderer from the North. I was shooting some 

 specimens of Eugenes fiilyens in the locality mentioned for 

 Amazilia dumerillii, when I saw and shot a male in one of the
