Aug 17, 1952

Larch Meadow, Jason Volcanic Natl. Park,
Shasta Co., Calif.
241 R. Holtonis.
Adult ?. When held, the call given is
a triplet in contrast to the single "croak"
of a ? aurea (Sonora Pesa) of the
same size.
Compared to R. b. aurina from Sonora Pesa,
these differences are noted:
Eyes of cascades large, closer together;
mask (faint) and maxillary stripe present;
more distinct barring on tibia; inky black
lateral spots.
