Silverstone NATURAL Risimt'dmr DEC 12 1969 Department of Biological Sciences ' University OF Southern California IIROARY AND Ix)s Angeles County Museum of Natural History lIDnHni No larva has been described for any member of the Marmoratus species group in the genus Leptodactylus. Recently Silverstone col-' lected the larvae of Leptodactylus hylaedactylus, a member of the Marmoratus group. The pui'pose of this report is to describe these larvae, to discuss the habitat of the adults and larvae, and to com-i ment on adaptations unique to this species within the genus. Materials, Methods, and Acknowledgments The report is based upon larvae from two foam nests from Regina, > French Guiana, now on deposit at the Los Angeles County Museum of Natural History (tadpole lots LACM 42082, 5 individuals; 42083, 7 individuals). Methods for examining the preserved material follow Heyer (in press). Priscilla H. Starrett (University of Southern California) and Robert F. Inger (Field Museum of Natural History) shared their knowledge of tadpole adaptation and morphology with us and read over the manuscript. Hymen Marx (FMNH) and Jay M. Savage (USC) critically reviewed the manuscript. Arden H. Brame, Jr. and John W. Wright (LACM) facilitated the use of the reported specimens. Marion Pahl (FMNH) illustrated the larvae. Betty Peyton (FMNH) typed the final copy. Silverstone was a National Defense Education Act Fellow at the University of Southern California during the field work and the com-pletion of the report.
