Greene, H. 1989 July 14 (continued) lab, it squirmed rapidly, coiled its incomplete but well healed tail around my fingers, and snapped off a segment. There was considerable bleeding from the proximal tail segment (remaining on the snake), and ~15-20 minutes later I was able to measure ~1 cc of blood in the plastic bag in which I immediately placed the snake. The tail flipped from my hand to the floor and thrashed rapidly and sinusly, and I started a stopwatch w/in 1-2 seconds of the break. Its movements were very regular and resulted in alternate flexion and coiling into a tight circle; the proximal end simply arched back and forth, but the distal end always marked very symmetrical S-curves. So, a series for the proximal end looked like: 71/1716. A series for the distal end looked like this: 02J/1605, after 5 minutes and 35 seconds the flexions had slowed noticeably, and for the first time flipped so the vertical surface was uppermost. At 8 minutes and 55 seconds the flexions began to be interrupted by brief pauses. At 9? minutes and 58 seconds, 11:29, 12:30, 13:44 movements only resumed after I pinched the tail. At 13 minutes and 59 seconds there was no evokable movement. The shed tail piece was 155 mm long, and weighed 5.4 g. The remainder of the snake wt. 43g; 425+82mm. at ~2230h I found the
