_Specimens examined_ (3).--1 mi. SW Inje, 1 (KU); 4 mi. NNE Sogwi-ri, Cheju Do, 2 (KU). _Description_ (KU 38774 from 1 mi. SW Inje).--Total length, 86 (head 13, body 40, tail 33); costal grooves (including axillary and inguinal), 13; two costal grooves between adpressed toes; length of inner branch of series of vomerine teeth less than distance between outer border of naris and peak of opposite series (tooth-rows V-shaped, approximately as long as broad); dorsal surface yellowish brown or buff (yellowish in life), having numerous blackish marks; venter yellowish cream, having an indistinct grayish mottling. _Remarks._--The salamander described above was found in a foxhole with another desiccated individual (not saved) on a military compound on April 24. The only other occurrence of _H. leechii_ on the mainland to come to our attention was the report of several larvae that were seen in a small pool on a hillside near Chip´o-ri in the summer of 1953. Each of the two specimens from Cheju Do (KU 38775-76) differs from KU 38774 in having (1) the length of inner branch of the vomerine series slightly greater than the distance between outer border of naris and peak of opposite series (tooth-rows V-shaped, longer than broad), (2) a dorsal and ventral keel on the tail, (3) one costal groove (rather than two costal grooves) between adpressed toes, and (4) in being darker both dorsally and ventrally. The area of buff on the dorsal surface of each specimen is reduced by a fine, blackish mottling and stippling, and the venter of each is grayish. Respective total lengths of KU 38775 and 38776 are 84 (head 12, body 36, tail 36) and 89 (12, 35, 42), and the number of costal grooves 13 and 14. Although the two specimens are of approximately the same size, the tail of KU 38776 is noticeably the longer; the tail of KU 38775 is thicker and deeper than that of KU 38776. The two specimens from 4 mi. NNE Sogwi-ri were taken on September 9 in damp substrate under volcanic rocks along a little-used road; although many rocks were overturned, only these two individuals were found. A South Korean soldier informed us that salamanders were fairly common on Cheju Do.
