Description: Cal. Acad. Sci. No. 32170, adult male, Wonsan, 

 Korea, collected by Victor Kuhne, June 7, 1911; 14 costal grooves; 

 appressed toes meeting; head width 7 in length from snout to vent; 

 head length 4 in length of body; head oval from above; eye longer 

 than distance from tip of snout; outline of upper jaw concave as seen 

 from side; angle of jaw back of hind angle of eye; upper and lower 

 eyelid fitting under a fold of skin behind ; a groove from hind angle of 

 eye to gular fold; a groove from this down behind angle of jaw; limbs 

 well developed; fingers 2 and 3 equal in length, 1 and 4 equal and 

 shorter than 2 and 3; toes 4, 3, 5, 2, 1 in order of length, a fold of skin 

 along hind edge of fibula and fifth toe; tail longer than body; cylindri- 

 cal throughout most of its length, flattened at tip; vent a longitudi- 

 nal slit joined at tip by two shorter oblique slits directed forward, and 

 joined one fourth its length back from the tip by two other similar 

 slits, opening of vent between tip and posterior short slits; vomerine 

 teeth in two series of about 19 teeth each; series beginning behind 

 middle of nares, curving forward and in to level of anterior edge of 

 nares, thence back and in, but not so far back in middle as on sides, 

 separated from its fellow by one-half width of naris; cream color

 same data, all have 14 costal grooves. Boulenger (1886) says " 14 or 

 15." In these three the third finger is longer than the second as in 0.
