April, 1906. The Ascaphus was secured on the southeast side 
of Mt. Rainier, in the vicinity of Reflection Lake, at an altitude 
of about 4861 feet. 
In 1911, it became possible to send Mr. Slevin on a collect- 
ing trip through western California, Oregon, and Washing- 
ton, and I requested him to look most carefully for Ascaphus 
both at Humptulips and on Mt. Rainier. At Humptutlips, late 
in July, he was unsuccessful, but on Mt. Rainier, in the middle 
of August, he secured three specimens of this toad. He has 
given me the following notes regarding their capture: 
“On August 16 and 17, I took three specimens of Ascaphus 
on the southwest side of Mt. Rainier, in what is known as In- 
dian Henry’s Hunting Grounds, at about 6000 ft. elevation. 
All three were found on bright sunny mornings between 10:30 
and noon, in a small slow-flowing stream. The one first taken 
jumped out of the brush into a small pool about four feet wide, 
five or six feet long, and two or three feet deep. It swam for 
a few seconds, just as a toad does; and when I attempted to 
catch it with my forceps, it went to the bottom and settled just 
like a frog—remaining perfectly motionless, its color blending 
with the color of the rocks and earth at the bottom of the pool. 
The second one I noticed in the same place, and I first saw him 
swimming about the middle of the pool just as I stepped down 
on the bank. While I was attempting to capture this specimen 
a third one jumped into the pool from the bank directly oppo- 
site me and went straight to the bottom. I collected both of 
these specimens, but a careful search and beating of brush in 
the vicinity failed to discover any more. All three specimens - 
were kept in a tin can, well punctured for ventilation, but they 
died within ten or twelve hours after capture.” 
These specimens are now numbers 30393, 30394 and 30395 
of the Academy’s collection. All appear to be adult males with 
enlarged testes and very large pads on the inner surface of the 
carpus. They measure from snout to anus: (No. 30394) 40 
mm., (No. 30393) 41 mm., and (No. 30395) 42 mm. 
The skin is nearly smooth in No. 30395, which has only 
a few warts over the pelvis and femur; but is moderately rough 
in No. 30394, which has warts or small tubercles scattered 
over the entire upper surface and sides of the head and body, 
and the upper surface of the arm, thigh, and leg. The para-
