it thrashes around quite a bit, and its gills
are not flexed nearly as frequently. Swallowing
seems to be accomplished in 3 different ways,
first, the deliberate opening of the mouth using
the palate separately; secondly, by a jumping
gulp in which the mouth is readily opened; and
thirdly, there seems to be some swallowing
accomplished without externally visible
activity, since the scales can be seen slowly
slipping [illegible] between the jaws without any
visible movement of the jaws or body. This
latter method was particularly evident during
the first 120 mm of swallowing. Now at
3:01 p.m. considerably more than the original
140 mm of reptile has passed through
this salamanders jaws. At 3:10 p.m. for
no apparent reason he again disgorged the
whole reptile. This time [illegible] it had
swallowed about 190 mm of the snake before
disgorging it. The water temperature where
the salamander was first seen is 59 F.
After disgorging this second time it
very actively fanned its gills back
and forth, continuously. At 3:20 p.m. the
salamander was killed, and both animals
preserved, being my catalogue numbers
146 and 147. When the salamander was
