In our specimens, _R. amurensis coreana_ differs from _R. temporaria dybowskii_ in having (1) smaller maximal size, (2) more slender body, (3) shorter legs, (4) incompletely webbed toes, (5) no mottling or barring on lips, (6) no contrasting barred pattern on hind legs, (7) dark brown stripes (usually) between dorsolateral folds, (8) a dark brown, linear mark below canthus, and (9) an immaculate ventral surface. Two additional distinguishing characters, which we found difficult to evaluate, are the nearly straight, dorsolateral folds, and lack of vocal sacs or ostia in males of _R. a. coreana_ (Shannon, 1956:38). Some of the differences between the two species were illustrated by Okada, 1931:107, fig. 48, _R. temporaria temporaria_ [=_R. t. dybowskii_] and 123, fig. 54, _R. temporaria coreana_ [=_R. amurensis coreana_]. =Rana temporaria dybowskii= Günther _Rana Dybowskii_ Günther, Ann. Mag. Nat. Hist., ser. 4, 17:387, May, 1876 (type locality, Abrek Bay, near Vladivostok, Siberia). _Rana temporaria dybowski_, Shannon, Herpetologica, 12:38, March 6, 1956. _Specimens examined_ (20).--Central National Forest, near Pup´yong-ni, 7 (KU); Chip´o-ri, 2 (KU); 1 mi. SW Inje, 6 (KU); 8 mi. SW Kangnung, 1 (KU); Taegwang-ni, 1 (KU); 1 mi. SW Tangjonggok, 3 (KU). _Remarks._--On October 9 in the Central National Forest, five individuals were found in a concrete-walled pit in old ruins on a wooded hillside; no specimens of _Rana amurensis coreana_ were taken there. _R. t. dybowskii_ was most often taken on high, moist slopes, and seemed to be especially common in forests. The specimen from 8 mi. SW Kangnung was obtained in a wooded area along a mountain stream. The earliest date of collection of a specimen of _dybowskii_ was March 7 at Taegwang-ni. See also the remarks under the preceding account of _Rana amurensis coreana_. The largest male among our specimens measured 65 in snout-vent length and the largest female, 79. Five gravid females had snout-vent lengths of 64, 68, 69, 69 and 70. =Trionyx sinensis= Wiegmann _Trionyx (Aspidonectes) sinensis_ Wiegmann, Nova Acta Acad. Leopold.-Carol., 17:189, 1835 (type locality, near Macao, China). _Specimen examined._--Han River, 5 mi. ESE Seoul, 1 (KU). _Remarks._--Our only specimen was purchased from a man who had captured it by hand in the Han River; it was the only turtle seen during our stay in Korea. Koreans eat turtles, and the elaborate (and relatively permanent) fish-traps that they construct across streams and small rivers probably reduce the size of populations of _T. sinensis_ and other species. =Eremias argus= Peters _Eremias argus_ Peters, Monatsber. preuss. Akad. Wiss., Berlin, p. 61, fig. 3 (for 1869), 1870 (type locality, Chefoo, China). _Specimens examined_ (23).--Chip´o-ri, 1 (KU); 5 mi. E Seoul, 3 (KU), 3 (UMMZ); 5 mi. ESE Seoul, 4 (KU); 6 mi. E Seoul, 10 (UMMZ); 7 mi. ESE Seoul, 2 (KU).
