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.
