trees. This habit was first announced by Ritter in 1903 in connection 
with observations on the breeding 1 habits of the species, and it has 
since been observed by other naturalists. Studies by Ritter (1903) 
and L. H. Miller (MS) were made on the Aneides population on 
the University of California campus at Berkeley. Miller had been 
engaged for some time in searching for Aneides. and finally, in 1898, 
discovered a female with eggs on the ground (see Ritter and Miller, 
1899). Industrious search in August and September of habitats 
known to be occupied by the species during the winter rainy period 
failed to yield additional specimens or eggs. In the summer of 1903 
workmen were engaged in cleaning out cavities in the large live oaks 
( Quercus agrifolia) on the University campus preparatory to filling 
the openings with cement, and during the progress of this work more 
than one hundred adult Aneides and at least twelve bunches of eggs 
were discovered. This material formed the basis of a brief paper by 
Ritter (1903) and a longer manuscript by Miller recently placed in 
my hands, excerpts from which are quoted in order to fill out the 
present account. 
I have found the species aboveground only once, when two indi- 
viduals of small size (approximately 42 and 70 millimeters in total 
length) were discovered under bark on an oak stub at a height of about 
4 feet (1.25 meters) aboveground. 
Aneides lives both on the ground and in trees. Practically all of 
the specimens in collections save those taken by Ritter and Miller have 
been found on the ground. The animals take shelter under stones, or 
boards which have lain on the ground for some time, in rotted stumps 
and logs, and at least two have been taken in nests of the brown-footed 
wood rat ( Neotoma fuscipes) . The salamanders are to be found in 
these habitats during the daytime, from the beginning of the rainy 
period (late September or early October) until about May. During 
the midsummer months, as indicated above, they disappear. Whether 
the animals ascend the trees only during the breeding season is 
unknown. The arboreal retreats need to be investigated during the 
winter rainy period in order to determine this point. Neither young 
nor adults are to be found on the ground during the summer dry 1 
period, and many individuals (35 in one instance: Miller, MS) were 
found to occupy single cavities aboveground. One group was found 
at a height of 30 feet above the ground. Miller (MS) says that these 
salamanders are great travelers. There is the possibility that the ter- 
restrial stock of Aneides simply retires to holes in the ground during
