221. Nothocercus sailed Bp. 

 Mazatlan, Grayson. 



" The present species inhabits the dark forests of the western tierra caliente ; it is solitary in its habits, and 

 is confined principally to walking upon the ground, feeding on various kinds of seeds, berries and insects. 

 During the season for incubation, which is in May and June, their long peculiar whistle can be heard for some 

 distance ; at such times an expert hunter, by imitating their notes, may easily call them to him ; in this way I 

 procured most of those shot by me. Their flesh is white and excellent, more tender and juicy than that of 

 the quail."
