316 BIRDS OF WESTERN AND 



292. SJrismatura dominica (Linn.). 

 Tepic, Grayson. 



" I found this duck, or several pairs, about fifty in all, that frequented a small lake or lagoon near the city 

 of Tepic in Jalisco, as late as the month of June. They were evidently desirous of breeding in that locality ; 

 the females shot by me showed enlarged ovaries. I have not met with this duck in the neighborhood of 

 Maaatlan."

« " Proc. Bost. Soc. of N. H., xiT, p. 302. 

 Mazatlan, Bischoff; Isabella Island, Grayson. 



" This species breeds upon the ground near the sea beach, the nest containing usually two eggs, or young. 

 The voice of the female is harsh, while that of the male is a shrill whistle. I never saw the male feeding the 

 young, although lie assists in incubation, and taking care of the young in the absence of the female. I found 

 them in great numbers breeding upon the Island of Isabella, and in the latter part of April the nests con- 

 tained nearly all young, or eggs ready to be hatched. One, and sometimes two, eggs in a nest, of a greenish 

 white, and rough on the outside ; inside of shell pale green. The nests were on the lower surface of the 

 island, near the sea, many on the sea beach ; the young are fed by inserting the bill down the old one's throat."

 of a goose egg."
