The eggs are from three to tive, short ovate, pale creamy Avhite, 

 spotted, principally at the large end and sparingly over tlie rest of 

 the snrface, with cinnamon-rnfons, mixed with lavender. Measurements 

 of three sets are as follows: 1.1 1 by 0.85, l.U) by O.-S.'}, 1.08 by 0.8;"), 1.07 

 by 0.85; 1.12 by 0.84, 1.10 by 0.82, 1.13 by 0.82, 1.07 by 0.83, 1.08 by 

 0.81; 1.10 by 0.82, 1.07 by 0.82, 1.10 by 0.83. Kests Avere found from 

 early in May until Jate in August. 



In a series of seventeen adults, including the typeof tlie species and 

 also that of P. lenvogtisfm Kidgw., 1 find a wide rang(^ of variation, 

 especially in tlie amount of wliite on the underparts. In individuals 

 recently adult, the white exttMids from the throat to the under tail- 

 coverts, including the tibia. In some specimens tliis is uninterrupted, 

 but in most of them there is a narrow pectoral band of cinnamon, with 

 faint wliite edges to the feathers when the plumage is fresh. In these 

 young adults the gray on the forehead and sides of head is often en- 

 tirely absent, or very dull and much restricted. The specimens before 

 mc show these variations in all stages. In some of the apparently old 

 adults the gray of the head is very restricted, and in one examph^ its 

 ])lace is taken by umber brown. The black and white bars of the 

 lower sides, Hanks, and under tail-coverts varies iiuu'h. In sonu', the 

 white bars are very narrow and in others quite broad. The black is 

 intense in some indivi<luals and dull in others. The variation in size 

 is also considerable, as an examination of the accompanying table of 

 measurements will show. The smallest specimen in the series is a 

 female from the Rio Frio. This bird, in addition to its small size, has 

 the shoulders and some of the wing-coverts very distinctly barred with 

 wliite ; the feathers thus barred are much darker than in ordinary birds, 

 in fact almost black. A bird from the Escon dido also has these barred 

 slioulders, and one other shows a faint approac^h to it. In the type of 

 P. leucor/astra some of the feathers of the under tail-coverts are tinged 

 with light rufus, an approach to which is noticed in other si)ecimens of 

 the series. I am unable to separate P. leucogastra from P. cinerciceps.
