* Gray has not adopted Linne's name H. esculenta. I quite agree with 

 Count Salvudori and many otliers, that there is no reason whatever to reject 

 it. Briss. Orn. ii. p. .510, pi. 46. fig. 2 a (1760), describes and figures a bird 

 with an edible nest; but it appears that they have nothing to do with one 

 another, the bird probably being some kind of Swallow, although the nest is 

 that of some species of CoUocalia. Linne (1758) quotes Rumphius, whose 

 description certainly refers to our bird.
