Abstract
The histology and histochemistry of serous glands of Hyla chrysoscelis, H. cinerea, Lithobates palustris and L. sphenocephalus are described, herein for the first time. Light microscopy was used for examination of glands. The glands are merocrine, externally secreting and composed of a syncytium of secretory cells surrounding a central lumen bordered superficially by melanophores. Serous gland numbers were compared within individuals and between species within a genus to test for differences between skin patches and species with and without conspicuous coloration. It was hypothesized no significant differences would exist within individuals and between species of a genus. Significant differences were found within individuals and between species. More serous glands were found in species with conspicuous coloration and more serous glands were found in conspicuously colored areas than in cryptic areas. These results suggest concealed conspicuous coloration in H. chrysoscelis and L. palustris is aposematic.
