the adult male and adult female. As all have hard skulls, and more- 

 over were collected at various times of the year (August, October, 

 and April), it is fair to presume that they represent birds in first 

 nuptial dress. 



This strikingly colored species ranges from the upper Tropical into 

 the lower Subtropical Zone, being found on the north slopes of the 

 San Lorenzo from the lower edge of the foothills up to 5,000 feet at 

 least, but is most numerous above 2,000 feet. It was recorded by 

 Simons from the foothills of the Eastern Andes, while both Mr. 

 Brown and the writer have taken it on the north slopes of the Sierra 

 Nevada. While the birds wander a great deal in search of food (be- 

 ing fruit-eaters exclusively), they breed only between 3,000 and 5,000 

 feet. The nest is built in a hole in a bank excavated by the female, 

 as shown by one found in such a situation at Las Vegas. In this case 

 the nest was built at the far end of a tunnel about two feet long dug 

 in the face of a bank along the road. The hole was about three 

 inches in diameter, with the end slightly enlarged to take the frail nest 

 of rootlets and other fibers. On May 14 it contained two slightly in- 

 cubated eggs, which were pure white in color. On June 12, 191 9, 

 another nest in an almost identical situation was found by the road- 

 side just above Agua Dulce at about 3,300 feet. It contained two 

 newly hatched young.

39 It has recently been proposed (Oberholser, Proceedings Biological Society 

 of Washington, XXXII, 1919, 46) to substitute Compsothlypidse for this group. 

 But by the International Code Compsothlypis itself would fall in favor of the 

 earlier Parula, although there seems to be a tacit understanding to ignore the 

 provision of the Code requiring such a change.
