Twenty snake s representing four species (genera Elaphe, Coluber, Agkistrodon) were observed undisturbed in a small cave in Mis- souri during the winter of 1964-65. Some snakes moved about in the cave while others retreated back into crevices where temperatures were higher. Only one snake remained in the same location throughout the winter. Juve- niles were found at greater depths in the cave than adults. The snakes' ac- tivity varied; Agkistrodon was the most a c t i v e, Coluber the least active. Temperatures within the cave proper ranged generally from 48? F to 58? F (8. 9? C to 10. 4? C). Observations indicate that a temperature increase did not signal the end of hibernation.
