accounts for their concentration at that particular spot. Iris dark 

 brown. 



108. Agytria Candida (Bourcier & Mulsante). 



This species, noticeable on account of its white underparts in con- 

 trast to the prevailing greenness of the moist lowlands, was frequently 

 noticed among the flowers of certain vines which climb to the tops of 

 the trees near the margins of clearings. Three specimens were taken 

 at Los Amates. None were observed elsewhere. Iris dark brown; 

 maxilla black; mandible pinkish; feet black. 



109. Saucerottea cyanura gautemalre subsp. nov. 



Type, No. 22,633, & a d-, Field Museum of Natural History; col- 

 lected at Mazatenango, Department of Suchitepequez, Guatemala, 

 by N. Dearborn, March i8th, 1906. 



Subspecific Characters: similar to 5. c. cyanura (Gould), but differs 

 from it in having: nape and interscapular region bottle-green instead 

 of grass-green; rump, middle primary coverts and greater secondary 

 coverts purple-bronze, instead of copper-bronze; greater primary 

 coverts black, instead of bronze; not more than half of the exposed 

 portion of the secondaries chestnut, instead of two-thirds chestnut; 

 and the chestnut under wing coverts tipped with dull purple for at 

 least a quarter of their length, instead of with a mere trace of dull 

 bronze. 



Description of type: Crown, nape and interscapulum shining bottle- 

 green ; lower back purple-bronze changing to shining plum-purple on 

 the rump; upper and under tail coverts and rectrices steel blue; 

 under parts glittering grass-green; thighs, a narrow line behind the 

 wings, and the bases of the chin-feathers, white; proximal half of the 

 secondaries and the bases of all but the three outer primaries, chestnut; 

 outer primaries and tips of secondaries dusky purple; under wing 

 coverts chestnut, tipped with dull purple; iris dark brown; maxilla 

 and tip of mandible black; base of mandible pale. Wing 53 mm.; 

 tail 31 mm.; culmen, entire, 21 mm., exposed, 18 mm. An adult 

 female, which equals the type in size has the feathers of the chin 

 slightly edged with white, and those of the abdomen edged with gray. 

 Otherwise the sexes are alike. A young male, taken March i5th, has 

 the lower breast and abdomen gray, but is like adults in other particu- 

 lars. 



Remarks: This hummingbird has heretofore been included with 

 cyanura, but when compared with specimens of that species from the
