Dullin 1949 Dicamptodon ensatus -3- Sept 2 3mi N Willow Creek, 700 ft., Humboldt Co., Calif. it closed down the posterior part of the palate first (perhaps catching against the posterior edges of the ventral scales) and then closed its mouth. With the closing of the mouth about 10 to 15 mm. of the snake disappeared inside. About 1:15 p.m. I moved the dish-pan to get some more photos and the Dicampt regurgitated the snake. Picking the snake up I found that it had tooth scratches for 140 mm along its ventral surface, and that it was covered with a slimy coating for nearly the same distance. The snake is 540 mm long but the salamander is only 260 mm. During a period from time of disgorging until 2:35 p.m. the snake lay in the water and the salamander moves less pooled around, occasionally coming to the surface to gulp air, but generally showing no particular activity or interest in the snake. At 2:35 p.m. just after taking a gulp of air, it grabbed the snake again, by the head and upside down. It swallowed the first 60 to 80 mm in about 30 seconds and now at 2:48 p.m. has about 135 mm of the original 140 mm back into its mouth. With the snake in its mouth
