moments later, I looked in and saw one of these small lizards hang- 
ing out of the mouth of one of my swifts. At intervals the swift 
shook the little fellow violently, took a vicious bite or two and im- 
proved his grip to such an extent that soon the Desert Night lizard 
had entirely disappeared within him. I tried one of the lizards with 
a dead vigilis by moving it about with a long wire. The dead lizard 
was seized and swallowed as was the live one of the same species. 
This spring a salamander^ Batraclioscps attenuatus, was placed by 
me on a piece of bark in front of two of my Rough-scaled Swifts. 
My attention was attracted to something else for a moment, so that 
when I looked back and saw that one of the lizards had changed his 
position and that the salamander had disappeared, I could not say 
that the lizard had eaten the salamander, because I had not seen him 
do it ; but circumstantial evidence was accusingly strong. 
In captivity the swifts eat at all times of the day during which it 
is light enough to see them eat. Foggy mornings make no diifer- 
ence if the weather be warm and the season summer. When fall of 
1916 came my swifts were, with the exception of injuries to iheir 
tails from ants which had attacked them, in excellent condition with 
plump rounded bellies that bulged with fat and nutriment to last them 
through the winter. When the cold weather arrived, they stopped 
eating and hid themselves beneath pieces of bark that lay under a 
thick covering of dead leaves, where they passed most of their time, 
except when the sun shone warm enough to entice them forth on a 
mild winter day. During the cold season, one died, but this spring 
the survivors came forth to take up anew their sunny existence as 
they strive optimistically for the pleasant things of life in spite of the 
inadequate care that is all I am able to bestow upon them.

SOME LAND SNAILS OF LOS ANGELES COUNTY 
E. P. Chace 
Most of th-e snails that have been found on the club trips during 
the past year have been turned over to me for determination. They 
have been very interesting as the distribution and scientific position 
of some of our local forms are still unsettled. 
To date the following species have been collected : 
Epiphragmophora tudiculata, Binney. The malleated snail. The 
color ranges from light brown to olive green, with a single dark 
band bordered by two narrow light ones ; mature specimens are quite 
round with a well rounded aperture and reflected and thickened lip.
