Gulliver 1949 Dicamptodon ensatus -4- Sept 2 3 mi. N Willow Creek, 700 ft., Humboldt Co., Cal.- 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
