Trochilus Linn.* 



Bill weak, longer than the head, broad at the base, and more or less curved, with the culmen rounded 

 the lateral margins dilated, especially at the base, and covering the lower mandible ; the nostrils basal, 

 with the opening closed by a large and partly plumose scale. Wings long and pointed, with the first 

 quill rather shorter than the second. Tail moderate and emarginated, with two prolonged narrow 

 feathers projecting much beyond the others. Tarsi very short, rather stout, and partly plumed. Toes 

 moderate, slender ; the inner one shorter than the outer, which is more united at the base than the inner 

 one ; the hind toe moderate, and armed with a moderate curved claw. 



The type of this genus is peculiar to the Island of Jamaica, and the habits, as described by Mr. Gosse, are very 

 similar to those of the genus Mellisuga.

Topaza G. R. Gray A 



Bill longer than the head, stout, and slightly curved, especially at the tip, which is acute ; the culmen 

 keeled above the nostrils, and then rounded, and the lateral margins dilated over the lower mandible ; 

 the nostrils basal, with the opening covered by a large scale, which is mostly concealed by the frontal 

 plumes. Wings long and pointed, with the first quill the longest. Tail moderate, broad, and slightly 

 emarginated or rounded, with two narrow feathers on each side prolonged beyond the others. Tarsi 

 very short, slender, and partly covered with plumes. Toes long and slender ; the lateral ones united 

 at the base, with the outer shorter than the inner one ; and the hind toe long, and armed with a small 

 curved claw. 



The species are inhabitants of the central and warmer parts of America. 



* Established by Linnaeus in 1748. It was originally founded in 1744, with the name of Troglodytes, by the same author. Les 

 Polythmus of M. Lesson, 1829, is coeval. 



t Established by M. Lesson under the designation of Les Topazes (1829).
