120 Messrs. Sclater and Salvin on the 



found a short distance from the village, up the stream of the 

 river Guacalate. Sometimes, however, it occurs about the lake. 

 In its actions it is lively and restless, little resembling the Ty- 

 rants in these respects. It is always found near water, and is 

 generally to be seen sitting on a stone on the margin, from 

 which it constantly darts to seize a fly or insect from the surface. 

 Mr. Gould possesses a Guatemalan example of this species in 

 no way differing from the Duofias bird.

This species occurs abundantly at Belize in December. At 

 Duenas it appears to be only a summer visitant, as it was found 

 breeding there in the month of May, not having previously been 

 observed. It builds a large loose nest with a great deal of 

 superfluous matter about it, the entrance being at one side. The 

 single nest found was composed entirely of small twigs, and 

 was placed at the end of a branch about twenty feet from the 

 ground. The eggs were laid about the third week in May. 

 They are slightly pear-shaped, and in colour of a pale creamy 

 white, spotted and blotched with brick-red ; they measure, 

 axis 1 in. 2i lines; diam. 10^ lines.
