Item On a hologynous species of the earthworm genus Diplocardia : with comments on oligochaete hologyny and "consecutive hermaphroditism". American Museum novitates ; no. 1886(New York, N.Y. : American Museum of Natural History, 1958) Gates, G. E. (Gordon Enoch), 1897-"The hologyny of D. sandersi is specific rather than sporadic, diagnostic in the genus, possibly unique among earthworms with biparental reproduction and older than in the parthenogenetic Enantiodrilus borellii. Postparthenogenetic evolutionary changes are responsible in E. borellii and Pontoscolex corethrurus for conditions previously regarded as evidence for consecutive hermaphroditism. Postparthenogentic sterilization of male gonads and conversion of testes to ovaries probably is gradual"--P. 8.Item On some earthworms from Burma. American Museum novitates ; no. 1555(New York : American Museum of Natural History, 1952) Gates, G. E. (Gordon Enoch), 1897-; Raven, Henry Cushier, 1889-1944.; Vernay-Hopwood Chindwin Expedition of the American Museum of Natural History (1934-1935)Item On some earthworms from Taiwan. American Museum novitates ; no. 1941(New York, N.Y. : American Museum of Natural History, 1959) Gates, G. E. (Gordon Enoch), 1897-"The 13 species represented in the collections hitherto available from the island of Formosa are all megascolecids and, with a single exception, of one genus. Two of the 12 pheretimas have been represented only by individuals too young to permit specific identification. Five of the others, as is the Perionyx, certainly are exotic (elongata from Malaysia, posthuma from southeast Asia, californica and diffringens perhaps from mainland China, bicincta from some part of the Pheretima domain east of Burma). Pheretima papulosa is peregrine, but its original home is unknown. The status of another (candida) is dubious. Two (aspergillum and incongrua) have been reported from the Chinese mainland, but little is known about their relationships and distribution. One species (formosae), presumably with biparental reproduction, certainly seems to be endemic in the island. Reproduction, in three of the exotic pheretimas, is parthenogenetic but in the other two, as well as in the Perionyx, is biparental. Absent in all of the collections are the European, American, and African exotics which have been so widely transported since the days of Henry the Navigator. Most, if not all, of the Formosan exotics may then have been brought to the island prior to arrival of Europeans in the Orient"--P. 19.Item On some miscellaneous lots of earthworms belonging to the American Museum of Natural History. American Museum novitates ; no. 1887(New York, N.Y. : American Museum of Natural History, 1958) Gates, G. E. (Gordon Enoch), 1897-; Lang, Herbert, 1879-1957.; Chapin, James Paul, 1889-1964.; American Museum Congo Expedition (1909-1915)Item On some species of the Oriental earthworm genus Pheretima Kinberg, 1867 : with key to species reported from the Americas. American Museum novitates ; no. 1888(New York, N.Y. : American Museum of Natural History, 1958) Gates, G. E. (Gordon Enoch), 1897-
