Description: Adult male, Cal. Acad. Sci. No. 26714, Nara, 

 Province Yamato, Hondo, collected by V. Kuhne, May, 1907; 14 

 costal grooves; 1 costal fold between appressed toes; head width 6| 

 in length from snout to vent; head length 3f in length of body; head 

 oval; eye as long as its distance from tip of snout; outline of upper 

 jaw straight as seen from side; angle of jaw back of hind angle of eye; 

 lower eyelid fitting under upper in front and behind; a groove from 

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

 well developed; fingers 2, 3, 4, 1 in order of length; toes 3, 2, 4, 1, 5 

 in order of length; a tubercle under base of both inner and outer 

 fingers and toes; tail shorter than body, trigonal at base, much flat- 

 tened in last two-thirds, not keeled or finned; vent formed of three 

 slits meeting, the posterior one quite short, the whole figure wider than 

 long; vomerine teeth beginning behind inner edge of nares; a forward, 

 incurving branch of 4 teeth; a branch of 17 teeth running straight 

 back and in ; series separated from its fellow anteriorly by twice width 

 of nares, meeting its fellow behind; length of series equalling distance 

 between outer edge of nares and peak of opposite series; color light 

 with heavy dark mottling; upper edge of tail light; sides of tail black; 

 belly light; total length, 99 mm., head 12.5, body 46, tail 40.5. 



Variation: an adult female, Cal. Acad. Sci. No. 25949, Central

The tail may be longer than the body; two males (Cal. Acad. Sci. 

 No. 25948, 25950, Central Hondo) have the vomerine series as long as 

 the distance between the outer edge of the nares and halfway between 

 the inner edge of the opposite nares and the peak of the opposite 

 series; No. 25950 shows the extreme breeding development of the 

 male vent; the longitudinal groove has disappeared and the vent is 

 formed by two grooves meeting in an angle, apex forward, a tubercle 

 indenting the apex of the angle; the coloration of this specimen is 

 light yellowish brown, almost obscured by heavy black mottling, light 

 gray below, sides of tail black, upper and lower edges of tail light. In
