299 bis. Add: Passerculus. beldingi. Brtpina’s SAVANNA Sparrow. ‘ Similar to 
the darker form of P. sandwichensis (i.e. bryanti), but much darker, with decidedly heavier 
dark: spotting on lower parts, the bill larger and more elongated.”? Salt marshes of the 
Pacific coast, from Santa Barbara south to Todos Santos Island, Lower California. Accord- 
ing to the A. O. U. Committee, what ornithologists have been calling ‘ Pusserculus anthinus” 
includes two distinct forms, one of which is now called ‘¢ Ammodramus sandwichensis bryanti,”” 
and the other is this Passerculus beldingi. P. “ bryanti’’ is described from San Francisco Bay, 
as ‘differing from P. sandwichensis alaudinus in decidedly smaller size and much darker 
coloration of the upper parts. There is little probability that such attempted discriminations 
will survive the official etiquette of the present flutter in American Ornithology.
