9. * Columbigallina passerina pallescens (Baird). 



Mexican Ground Dove. 

 Two specimens : 



a. Chichen-Itza, 189- E. H. Thompson. 



b. £, San Ignacio, February 9, 1904. 



Chapman reports this bird as common at Chichen-Itza. I supposed that I 

 had seen both species of Ground Dove there, but find only C. ruftpennis among 

 my skins. I obtained one specimen (a male) of the present species at San 

 Ignacio, on February 9, and have a specimen from Chichen-Itza in the 

 Thompson collection. 



10. * Columbigallina rufipennis (Bonaparte). 



Rufous Ground Dove. 

 Maya name, mu-kui. 

 Five specimens : 



a. 9 , Feb. 26, 1904. 



b. 9, March 28, 1904. 



c. £, April 3, 1904. 



d. £, April 3, 1904. 



e. fledgling, March 28, 1904 (alcoholic). 



Very abundant and tame about the yard, garden, and corrals at Chichen. 



Two nests of this species were collected on March 28. They were situated 

 in lime trees in the garden, and not over thirty meters from the house. One 

 of the nests was first discovered on March 26, at which time it contained a 

 single egg ; on the 28th there were two eggs, both of which were fresh. They 

 are equally rounded at either end, and measure respectively 2 1.8 mm. X 16 mm., 

 and 22 mm. X 16.5 mm. 



The other nest contained a single fledgling. The female, when disturbed, 

 flew to the ground and fluttered away as if wounded. The nest was placed 

 next to the main shaft of the tree on a small branch, at about three meters 

 from the ground. Both nests are about 9 cm. in diameter and 5 or 6 cm. 

 deep. In one (that containing the eggs) the depression is very slight ; in the 

 other the cup is rather deep (about 2 cm.), suggesting the possibility that the 

 nest is added to after the eggs are laid. It seems more probable from its 

 appearance, however, that this is an individual variation in construction. 

 Both nests have a foundation of lime or other leaves, the upper part being 

 rather compactly built of small stems, with a little grass and a few rootlets.
