In 1954, two of us (Jones and Byers) collected reptiles and amphibians in Korea incidental to field studies relating to hemorrhagic fever. The 382 specimens thus obtained were deposited either in the Museum of Natural History of The University of Kansas (KU), or in the Museum of Zoology of the University of Michigan (UMMZ), and are the basis for the present report. Continuous American military operations of one sort or another in Korea since 1945 have afforded opportunities for interested persons to obtain there collections of amphibians and reptiles, the study of which has resulted in several recent publications (Babb, 1955; Dixon, 1956; Hahn, 1959 and 1960; Shannon, 1956 and 1957; Stewart, 1953 and 1954; Tanner, 1953; Walley, 1958_a_ and 1958_b_). This paper, which contains comments on the natural history and taxonomy of 22 species, all previously reported from Korea, supplements earlier studies, especially Shannon's (1956) annotated list of the herpetofauna of the country. Shannon (_loc. cit._) recorded 36 kinds of reptiles and amphibians from Korea. Subsequently, _Bufo stejnegeri_ (previously omitted) was added by Shannon (1957), _Takydromus takydromoides oldi_ was described by Walley (1958_a_), and _Takydromus kwangakuensis_ was relegated to synonymy under _T. amurensis_ by Walley (1958_b_). Presently, then, 37 kinds are on record from the Korean Peninsula. In the accounts beyond, Jones and Byers are mostly responsible for the remarks on natural history, whereas Webb is mostly responsible for the taxonomic comments. The synonymies include (1) the original description, which is followed by (2) the first use of the name-combination here employed if it differs from the name as originally proposed, and (3) any synonyms having type localities in Korea. All measurements are in millimeters and all dates refer to the year 1954 unless otherwise indicated. A gazetteer of localities mentioned in the text and a list of literature cited follow the accounts of species. We are grateful to the officers, enlisted men and civilians associated in 1954 with the Field Unit of the Commission on Hemorrhagic Fever, Armed Forces Epidemiological Board, who aided our efforts in Korea; we are especially mindful of the contributions of Dr. Albert A. Barber, Dr. Marshall Hertig, Mr. Louis J. Lipovsky and Dr. Warren D. Thomas. We are grateful also to Mr. Yoshinori Imaizumi, National Science Museum of Japan, for his translations of several papers in Japanese, and to Dr. Edward H. Taylor for making certain pertinent references available to us. =Hynobius leechii= Boulenger _Hynobius Leechii_ Boulenger, Ann. Mag. Nat.
