Abstract
1. 1. Oxygen affinity of blood of five lizard species was measured at 25, 35 and 40°C and pCO 2's of 38 and 76 mm Hg. 2. 2. At its activity temperature each species had a P 50 of 68–72 mm Hg. Oxygen affinity was also related to body size. 3. 3. There was a seasonal shift in oxygen affinity in Dipsosaurus dorsalis. 4. 4. There was no difference in oxygen affinity of blood of Sceloporus occidentalis from sea level and from 6000 ft. 5. 5. There was no correlation between sensitivity to CO 2 and fossorial habits. 6. 6. An anguid ( Gerrhonotus multicarinatus) showed less sensitivity to changes in temperature and pCO 2 than iguanids.
