Summary
In the course of a study of Algae from Indian soils two new species of Chlamydomonas (C. Iyengari, C. indica) and a new species of Carteria (C. eugametos) were observed which are distinctive in the fact that their gametes conjugate by their posterior ends. Diagnoses of the new species are given. The gametes are provided with membranes. One of the fusing gametes receives the contents of the other, and the membrane of the active gamete, which has fused with that of the recipient gamete, forms a loose envelope around the zygote. The zygotes retain only the flagella of the recipient gamete. They are larger than the vegetative cells and may remain motile for some days. They frequently divide without a resting period, although zygospores were formed in old cultures of two of the species. Germination of these zygospores was observed.
