Abstract
A comparative study was made of the carbohydrate moiety of the egg jelly in three species of Hynobius, H. retardatus, H, nigrescens, and H. tokyoensis, by means of paper partition chromatography. These three species present no species-specific monosaccharide pattern, having a similar, though not wholly identical, pattern which contains mainly fucose, mannose, and galactose. At present, however, it remains uncertain whether this profound similarity between the monosaccharide patterns can be relied upon as a biochemical manifestation of genus specificity in the egg jelly of Hynobius.
