The largest female from our series (KU 38816) measured 740 (620 + 120), and the largest male (KU 38813), 595 (475 + 120). Respective ventral and subcaudal counts of 13 males averaged 170.5 (167-174) and 60.0 (56-63), ventrals of 12 females averaged 178.3 (169-182), and subcaudals of 11 averaged 51.0 (46-56).

_Specimens examined_ (7).--Central National Forest, near Pup´yong-ni, 2 (KU), 1 (UMMZ); 4½ mi. W Chip´o-ri, 1 (KU); 5 mi. N P´yong-taek, 1 (KU); 5 mi. E Seoul, 1 (KU); 5 mi. ESE Seoul, 1 (KU).
_Remarks._--Individuals were observed or taken on dry, scrubby hillsides and in grassy upland areas. One of the three snakes from the Central National Forest was captured on a steep, forested hillside among granite outcroppings; another was obtained there along a stream bank and had eaten three bats, _Murina aurata_ (see Jones, 1960:265), and one mouse, _Apodemus_ sp. (tail only found). P. M. Youngman reported (personal communication) finding a rat (_Rattus_ sp.) in the stomach of one individual. A female (KU 38830, length of body, 1180) that was obtained on June 2 contained 17 eggs, each approximately 32 mm. long. The ventrals of two females numbered 223 and 229, and the subcaudals of the latter 70. Ventrals and subcaudals of five males were, respectively, 211, 213, 214, 215, 216, and 71, 75, 75, 69, 75.
The coloration and pattern of our seven specimens are of interest in view of the probable intergradation between _E. s. anomala_ and _E. s. schrencki_ in northern Korea (see comments by Shannon, 1956:46). The smallest specimen (KU 38831), having a total length of 335 (280 + 55), was obtained 4 mi. N P´yong-taek on September 24. It is nearly uniform pale brown (lacks a dorsal pattern) and additionally is characterized as follows: incomplete pattern on the head; no black postocular band (pale brown with black posterior border); ventrolateral extensions of the head pattern that form longitudinal stripes of white on the third row of scales; a pale whitish stripe on the sixth and seventh scale rows that extends posteriorly to the level of the fortieth ventral and that has a narrow black border (sometimes interrupted); small and indistinct blackish markings and pale stripes on sides (no higher than sixth row of scales); underside of the head whitish; and venter grayish, having blackish margins on the ends of ventrals posteriorly. KU 38831 is unusual and perhaps anomalous in having a pattern that does not conform to the juvenile pattern of either subspecies.
