The fortunes of a group of four adults and two young individuals 
which lived beneath boxes and boards in a grove of Pittosporum trees 
on the Berkeley campus were followed for a time in the winter of 
1921-22. During the spring of 1921 all of the salamanders of this 
species, with possibly one exception, had been removed. None was seen 
during the dry summer period, but with the first autumn rains several 
individuals of eschscholtzU appeared. Repeated daytime examinations 
during November and December showed that the animals made fre- 
quent changes of location. On one day they would be under a large 
box beside a building; on another occasion they would be found out 
under boards, 20 feet away but still in the leaf mat under the trees. 
The young moved about in the same way as the adults. Evidently 
any convenient shelter served as harbor for the animals during the 
day, their restriction to the general neighborhood being brought about 
by the zone of harder and drier ground outside the grove and also 
by the lack of shelter in that direction. 
The box which furnished the principal shelter for the salamanders 
was removed on January 24, 1922, up to which time the animals 
had been present continuously; thereafter they could not be found. 
Another box placed in the same location a day or two later failed to 
attract any salamanders. This suggests that the original population 
comprised the only individuals of eschscholtzU present in the grove, 
and that when their principal daytime .shelter was removed the 
animals made a permanent change of base, after which they did not 
return to their former haunt. 
Captive specimens when handled sometimes stand up high on their 
toes. When handled roughly by grasping the head or body the tail 
is apt to be swept around laterally — alligator fashion — and at the 
same time the glands on the tail begin to secrete a colorless fluid. This 
species displays some agility in movement; when dropped from the 
hand an individual usually manages to turn during the course of the 
descent so as to alight on the feet, or at least on the ventral surface. 
Van Denburgh (1898, pp. 140-141) was first to report the breeding 
habits of this species. A female, with three eggs, was found under 
a decayed log in the redwoods at Mill Valley, Marin County, April 19, 
1896. The salamander and eggs were placed with bits of wood and 
damp moss in a darkened jar. The female at once took charge of 
the eggs, 
. . . lying beside them and bolding them in a loop of its tail. Evidently dis- 
satisfied with their position and surroundings, the Plethodon [= Ensatina'] moved 
the eggs from place to place in the jar, holding them always in the crook of its
