1883.] MR. A. BOUCARD ON BIRDS FROM YUCATAN. 451 



100. Lampornis prevosti (Less.). 



Very rare ; only four specimens seen, all of which were killed. It 

 lives only in the loneliest forests, far from the dwellings of man, but 

 is not very shy. Izalam, February. 



101. Trochiltjs coltjbris, Linn. 

 Abundant on the coast. 



102. DoRYCHA ELis^ (Lesson). 



Found only at the port of Progreso, where it is very abundant all 

 the year. I have never seen one of these birds elsewhere. It is a 

 very swift flier, shy and rather noisy. It stops but an instant, and 

 again darts away, so that it can rarely be shot upon the perch. 



103. Amazilia cinnamomea (Lesson); Lawr. Ann. Lye. N. Y. 

 ix. p. 204. 



This bird is the rarest of all the Humming-birds yet found in 

 Yucatan. Only one specimen has been seen during the year. This 

 specimen was shot while hovering about some flowers in a very high 

 tree. Its habits are not known to me. 



104. Amazilia yucatanensis, Cabot. 



Seems to be a very rare species, only four specimens having been 

 sent by Mr. Gaumer. 



105. Amazilia devillii (Bourc). 

 [Not seen by me. — 0. S.'] 



• 106. Chlorostilbon caniveti (Lesson). 



This beautiful little Humming-bird was very abundant in Izalam 

 in January and February. 



107. Ch^tura gaumeri, Lawr. Ann. N. Y. Ac. Sc. ii. p. 245. 

 Ghcetura vauxi, Lawr. Ann. Lye. N. Y. ix. p. 204. 



[Not submitted to me. — O. /S.] 



108. Chordeiles texensis, Lawrence, I. c. p. 204. 

 Only once met with. 



109. Antrostomus macromystax (Wagl.). 



Very common in Merida. Frequents the roads and by-paths ; 

 appears in the evening after sunset, and often continues its wander- 

 ings all night. 



I am not certain that the specimen examined is correctly deter- 

 mined. 



no. Nyctidromus albicollis (G-m.); Lawr, I. c. p. 204. 



This is the most common of all the Caprimulgidae in Yucatan. 

 It is found in all parts of the country, appearing early and flying all 

 night.
