lined with fine rootlets and a few horse-hairs. It measures inside 2.75 

 inches in diameter by 1.50 in depth. The nest contained two fresh eggs, 

 white with a faint bluish tinge, thinly speckled with cinnamon except at 

 the larger end where the spots are more of a chestnut, larger, and crowded 

 together, forming a distinct band. The eggs are eliptical ovate and 

 measure .91 X .64 and .90 X .66 inch. 



Young birds differ decidedly from the adult, and may be described as 

 follows : ((J juv., no. 4977, M. N. de C. R., San }ose, June 6, 1S90, Geo. K. 

 Cherrie). Above, bistre brown with olive shading; less olive and deeper 

 brown on crown and occiput; most of the feathers with a blackish bar 

 across the tip, giving the back a somewhat mottled appearance. Wing- 

 coverts olive brown, the greater series tipped with tawny olive, forming a 

 distinct band. Remiges dusky. Forehead and auriculars black. Cheeks 

 and loral region whitish, mottled with dusky. Throat whitish, faintly 

 speckled with dusky tips to the feathers. Breast and sides dusky wood- 

 brown, becoming paler and more bully on belly and crissum. Breast and 

 belly with distinct dusky stripes. The adult plumage is attained by the 

 first moult, which goes on comparatively slowly, requiring about three 

 months for its completion. The plumage of the young has almost en- 

 tirely disappeared below, before the moult commences on the back. 



I have not noted the species below an altitude of 2S00 feet, nor above 

 5000 feet. 



63. Pyrgisoma leucotis. — Rare about San Josd, but common enough at 

 a slightly lower altitude. Its habits are similar to those of P. cabaiiisi. 

 The nest and eggs I have not met with, but several broods of young are 

 reared each year, biids just from the nest being found from June until 

 November. I think birds do not attain the completely adu^t })lumage 

 until the second year, differing, however, only in having a dusky 

 oli\e hi-own head, instead of black, and the upper back more ashy. 

 Young birds are very much browner above and are faintly mottled with 

 blackish tips to many of the feathers. The throat is blackish, lireast 

 dusky olive mottled \s\\\\ dusky, belh- olive yellowish, crissum and flanks 

 rufous. 



64. Spinas mexicanus. — Tolerably common resident. 



65. Eucorystes wagleri.- — Seldom met with about San Jos^. I think 

 that only one brood of young is reared each year. Young birds are uni- 

 form black above with a slight gloss, rump brownish. The crown and 

 occiput and sides of head are like the back, but there is a broad pale 

 yellowish supraloral stripe extending to just back of the eye; in some 

 examples the yellowish color meets in a band across the forehead. 

 Throat, breast, belly and thighs dusky blackish with faint brownish 

 shade; crissum tawny. 



66. Amblycercus holosericeus. — Not common in the vicinity of the city 

 Common on both the Atlantic and Pacific slopes down as far as the coast, 

 and I have taken examples at an altitude of over 6000 feet. The young do 

 not difter from the adult.
