glistened from the blue throat. On November 13 I took another at 

 flowers near the village and noted that the tail was raised constantly 

 until it formed a right angle with the line of the back. Another was 

 secured on November 15 from a high perch on a dead twig. 



Of the race xenoura of Griscom ^^ I have seen a pair from the type 

 locality. The male shows the narrower chestnut bar on the outer tail 

 feathers that is given as the principal character, when compared with 

 a good series from Guatemala and southern Mexico. Two males in 

 the American Museum of Natural History from Matagalpa and 

 Quilali, Nicaragua, surprisingly, are like the typical form.

 Carolina ) . 



At Panajachel these northern migrants were common about flowers, 

 so that I secured three males and a female November 11, 12, 13, 

 and 15. 



The males had begun to molt so that a spot in the center of the 

 throat has the new metallic red feathers of the adult plumage with 

 one or two scattered new feathers at the side. The rectrices are still 

 those of the juvenal j^lumage.

An adult male was taken about flowers at 10,000 feet elevation 

 near the great rock Maria Tecum, Department of Totonicapam, 

 November 24. This bird has the chestnut markings on axillars, sides, 

 and inner webs of the outer rectrices as w^ell as the small bill that 

 mark this race from typical S. p. platycercus of farther north. It 

 measures as follows : Wing 46.9, tail 30, culmen from base 15.7 mm. 



There is one other male in the National Museum collected by Sal- 

 vin, labeled only as from Guatemala.

Near Sierra Santa Elena these were the most common humming- 

 birds, six being obtained between November 18 and 23. They were 

 found about little openings in the forest where they worked about 

 flowers with the animation customary in their family, the males
