Lycodon rufo-zonatus Cantor, Ann. Mag. Nat. Hist., ser. 1, 9:483, August, 1842 (type locality, island of Chusan, China).
Dinodon rufozonatus, Peters, Sitzungsber. Gesell. naturf. Freunde Berlin, p. 89, 1881.
Specimens examined (4).—Central National Forest, near Pup´yong-ni, 3 (KU); Yongsan (Seoul), 1 (UMMZ).
Remarks.—The three specimens from the Central National Forest were taken in the period August 12-26. Two were caught in live-traps set for small mammals in deep forest among granite outcrops. The specimen from Yongsan was obtained on October 27 in a partly wooded area. Ventrals and subcaudals of our four specimens (all males) numbered, respectively, 198, 200, 198, 205, and 74, 75, 75, __. Total length of the largest specimen was 960 (790 + 170).
We follow Chang (1932:54) and most subsequent authors in regarding D. rufozonatum as a monotypic species.

The length of body measured approximately 550 and the length of incomplete tail 168 in one specimen (KU 38777, female from 5 mi. ESE Seoul), 540 and 183 in the other (KU 38778, female from Cheju Do). Respective ventral and subcaudal counts of the two females are 204, 194, and 74+, 86.
