THE REPRODUCTIVE CYCLES OF THREE VIVIPAROUS TELEOSTS, ALLOOPHORUS ROBUSTUS, GOODEA LUITPOLDII AND NEOOPHORUS DIAZI1 GUILLERMO MENDOZA Biology Department, Grinncll College, Grinnell, lozva Extensive taxonomic and descriptive work has been done on the Goodeidae, a family of fresh-water viviparous cyprinodonts from Mexico, but very little is known about their reproductive cycles. Except for a detailed three-year laboratory study on Neotoca bilincata (Mendoza, 1939), no other major study on the reproductive cycles of the goodeids has been made either in the laboratory or in the field. The only other principal source of information on the breeding cycles in the family is in Meek (1904), in which a brief and inadequate statement is included in the taxonomic description of each species. Miscellaneous information on the reproductive cycles of the goodeids also is scattered in many of Turner's articles but he made no detailed study of any one species. Because of the scarcity of this information, it was proposed to make an analysis, from field specimens, of the female reproductive cycles of three species in the family. This study concerns the duration of the female cycle, the number and size of broods, the length of the gestation period, etc. This is the first intensive study that has been made of the reproductive cycles from specimens collected in their natural habitat. The writer is greatly indebted to Sr. Aurelio Solorzano Preciado, Director of the Estacion Limnologica in Patzcuaro, Michoacan, and to Juan Piza M., one of the attendants at the station, for their unending cooperation in helping the writer to make many of these collections. MATERIALS AND METHODS This study concerns three members of the family Goodeidae: Alloophorus robus- tus (Bean), Goodca luitpoldii (Therese von Bayern and Steindachner), and Neo- ophonis diazi (Meek). The three species were collected from Lake Patzcuaro. They were chosen
