Hah. Mexico, Tres Marias Is. {Grayson ^ ^, Forrer ^, Nelson ^ ^). 



We agree Trith Mr. Nelson in separating this Tres Marias Dove as a distinct species 

 from L. brachyptera of the mainland, on account of its paler colour and stouter bill. 

 Count Salvadori has remarked on the lighter shade of plumage of the birds from these 

 islands, and there is no doubt that the back of the neck is of a more coppery-violet 

 than in typical L. brachyptera. We have only one pair of L. capitalis in our collection, 

 and both birds are somewhat darker than those from the mainland ; this, however, may 

 be accounted for by their preservation in spirits. Mr. Nelson ^ remarks that this Dove 

 is very common on Maria Madre and Maria Magdalena, and probably also occurs on 

 ^laria Cleofa. He says that L. capitalis runs about like a small Quail in the quiet 

 shade of the forest-trails, only disappearing into the thicket or noiselessly flying close 

 to the ground if slightly disturbed, but if hard pressed it rises with a loud whirring 

 sound and darts through the intricate mazes of the densest forest with an agility 

 equalled by few other birds. In the heat of the day it retires to shady places, and 

 usually perches amongst the densest foliage, from whence the birds call to each other 

 at frequent intervals. During the breeding-season they may be seen in pairs keeping 

 close together, but at other times they are solitary.
