_Remarks._--The specimen from Cheju Do was captured on September 9 in tall grass near a small stream and was eating a small _Rhabdophis tigrina_. The female from near Seoul was obtained from a Korean on June 10, and was gravid (six eggs, each approximately 35 mm. in length). 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. There is some disagreement in the literature as to the proper generic name of this snake. Differences in dentition between Old World species (referable to _Zamenis_) and the American species (referable to _Coluber_) are discussed by Bogert and Oliver (1945:365). The species _spinalis_ has been referred to _Coluber_ by several authors (see Pope, 1935:226). =Elaphe dione= (Pallas) _Coluber dione_ Pallas, Reise durch verschiedene Provinzen des Russischen Reichs, 2:717, 1773 (type locality, "Salt steppes toward the Caspian Sea" according to Stejneger, Bull. U. S. Nat. Mus., 58:315, July 22, 1907). _Elaphis dione_, Duméril and Bibron, Erpétologie générale ..., 7:248, 1854. _Specimens examined_ (10).--Choksong, 1 (KU); 4 mi. N Ch´onan, 1 (KU); Seoul, 1 (KU); 5 mi. E Seoul, 1 (KU), 2 (UMMZ); 5 mi. ESE Seoul, 1 (KU); 6 mi. E Seoul, 1 (UMMZ); Taegwang-ni, 1 (KU); 2 mi. WSW Tongjonggok, 1 (KU). _Remarks._--This species seemingly occurs in upland habitats. Specimens were taken on rocky hillsides, on sparsely wooded hillsides, and in cultivated fields. November 21 was the latest date of capture of an active individual (UMMZ 113451), the head of which was seen many times prior to capture protruding from a hole beneath the concrete floor of a building. A female (KU 38855), measuring 915 (775 + 140) in total length, and obtained on June 13, contained nine eggs (32 mm. long). One juvenile had eaten a half-grown house mouse, _Mus musculus_; the stomach of a male contained three mice, one a striped field mouse, _Apodemus agrarius_, the other two probably also of that species but too far digested for certain identification. Eggs probably hatch in late summer. A young of the year (length of body, 340) was captured on September 30; another juvenile (length of body, 285) was obtained in May. Our largest male (KU 40123) measured 904 (719 + 185) in total length. Ventrals and subcaudals of six females averaged 205.8 (198-211) and 62.2 (55-69), respectively, whereas corresponding counts of four males averaged 196.8 (190-214), and 71.0 (69-74). Each of nine specimens had dorsal scales in 23-25-19 rows except one (UMMZ 113451), which had 23-25-23 rows. =Elaphe rufodorsata= (Cantor) _Tropidonotus rufodorsatus_ Cantor, Ann. Mag. Nat.
