Results of the Archbold Expeditions. No. 78. Frogs of the Papuan Hylid Genus Nyctimystes

Many specimens of the hitherto little-known genus of tree frogs Nyctimystes are included in the extensive herpetological material ob-tained by the five Archbold Expeditions to New Guinea. The study of this material and other important specimens obtained in central New Guinea by E. Thomas Gilliard makes it possible to redefine the genus Nyctirnystes and to add several new species to the known fauna of New Guinea. In addition to the specimens in the collection of the American Museum of Natural History, I have examined specimens in the Car-negie Museum through the generosity of Dr. M. Graham Netting, and the Nyctimystes in the collection of the Museum of Comparative Zoology through the courtesy of Mr. Arthur Loveridge. I am grateful to Mrs. Frances W. Zweifel, who prepared figures 1, 2, 4, 7, 11, 14, and 16, and aided in the preparation of most other illustrations. Mr. Charles M. Bogert is due thanks for reading and helpfully criticizing the manuscript. For catalogued specimens, the following abbreviations are used
