neither of these two size-groups did any of the individuals show that 
eggs were being, or had been, developed. The third group, of 9 ani- 
mals, measures about 57 to 62 millimeters in length; and the fourth 
of 4 individuals about 70 to 74 millimeters. In both the latter groups 
the animals were in breeding condition and contained eggs. 
Male toads in the collection fall into two groups: 50 to 55 milli- 
meters, and 58 to 64 millimeters in length. These specimens were 
practically all collected in meadow ponds or streams and were breed- 
ing animals, for they have nuptial excrescences on the inner digits of 
the fore limbs. They are believed to represent animals three and four 
(or more) years of age. No males were obtained which could be called 
younger than these. Such individuals would probably be found by 
careful search on the upper slopes some distance from the breeding 
ponds. 
“The food of the Yosemite Toad includes a wide variety of insects 
and the like. One individual captured at Porcupine Plat, June 29, 
1915, contained two Tenebrionid beetles, several weevils of different 
species, numerous large ants, and one centipede, besides some red fir 
needles probably taken incidentally.” (Quoted items from Grinnell 
and Storer, loc. cit.)
