231. P. gutta'tus. (Lat. guttatus, spotted; gutta, a drop.) St. Lucas Savanna Sparrow. 

 BUI shaped as in rostraims, relatively as stout, but smaller ; culmen 0.45 ; depth at base 0.25. 

 Bird smaller : pattern of coloration the same, but tone darker ; streaking of the under parts 

 sharper, heavier, and darker. Instead of the light brownish-gray of rostratus the upper parts 

 are here dark, almost olivaceous, brown, so that the dark streaking of the crown and inter- 

 scapulars is less noticeable. The same difference characterizes the under parts. Cape St. 

 Lucas. 



Obs. There is a sparrow of the L. Cala. Gulf coast and islands like guttatus : larger ; 

 wing 2.75 ; biU. 0.50, at base 0.30 deep, thus as large as that of rostratus, but regularly conic, 

 with straight culmen suddenly deflected at end, and perfectly straight commissure; upper 

 mandible and tip of lower blackish ; rest apparently yellowish. An n. sp. f P. sanctorum
