1. Glycidamins were prepared from the jelly of toad (Bufo vulgaris formosus Boulenger) and frog (Rana japonica Guenther) eggs. 2. The toad mucinogen and mucin involved hexosamine and galac-tose in the molecular ratio of 2:3 and the frog mucinogen in the corres-ponding ratio of 1:2. Methylpentose was detected but was small. 3. Galactose of the toad mucinogen hydrochloride was identified as the methylphenylhydrazone. 4. The preparations from the toad jelly were found A group-active, but those from the frog jelly not. We are indebted to the Grant Committee for Scientific Researches. of the Education Department for a grant which covered the expenses of this work.
