[part I. ; length of bill from forehead, .55, from noatril, .34, along gape, .62; tarsus, .CO. The comparison of many specimens of the grayheaded Hylophilus of Guatemala, with others from Panama, exhibits, on the wliole, the differences referred to, as stated by Mr. Lawrence, but they are ex- ceedingly slight, and may not unreasonably be referred to the influ- ence of season or locality. Of the three types of Mr. Lawrence, two, in which the olive green of the cap is most distinct, and the size least, are decidedly immature birds ; the third (No. 400), how- ever, is adult, and although the color referred to is reduced in amount, it is still quite appreciable. ⢠Unmistakably auult specimens from Costa Rica and Nicaragua are still smaller than those from Panama, as shown by the measure- ments given above. They are even brighter yellowish above than in the type, the edges of some of the feathers almost yellow. Com- pared with Guatemalan skins of unmistakable decurtatus, the difference is very appreciable. ; , â ...j ,â¢, ^. ,.,3} A young bird, scarcely full fledged, has the olive of back soiled with buff, the top of head is dull sepia brown, and the olive of back is tinged with the same. I am not satisfied as to th" existence of more than one species, but for the present retain pusilltis, and await further evidence to determine the question. , ; . â ->" Smith- CollPc- Sex When Collected.
