摘要："(1) Ambystoma annulatum lays its eggs in water after rains in late September. (2) The eggs and embryos agree essentially with those of A. jeffersonianum. (3) The previous report of A. annulatum laying eggs on land suggests that the species is flexible in the choice of an egg-laying site. (4) Plethodon glutinosus lays its eggs in late summer in caves in northern Arkansas. The eggs and embryos agree essentially with those of P. cinereus except that there is no stalk of attachment for the egg-cluster and the egg-number averages greater. (5) The egg-capsule number exhibits some variation in preserved material. At least two egg-capsules and a vitelline membrane are present. The inner egg-capsule is normally subdivided into two and frequently into more capsules. (6) P. glutinosus passes through a poorly defined striped pattern during its ontogeny"--P. 11.
