HERPETOLOGY OF JAPAN. 31 



limbs moderate, fingers and toes when laid against the body over- 

 hipj)ing; fingers and toes rather long, depressed, without webs; fifth 

 toe well developed, nearly e((iialing first toe, though not as long as 

 third finger; tail long, equaling the length of head and body, com- 

 pressed from the base, tapering, pointed at end, with a dorsal fin 

 beginning at the basal first third and a lower ventral fin in the ter- 

 nnnal fourth; 13 distinct costal grooves including the axillar and 

 inguinal ones; a median dorsal groove; parotoid gland indistinct; 

 postocular groove indistinct; gular fold well marked; vent (male) a 

 longitudinal slit bifurcating anteriorly, with a papilla in the fork, 

 borders swollen. Color (in alcohol) above dull isabella-color, the 

 upper surface with indistinct paler marblings; imderneath pale drab- 

 gray; the entire surface above and l^elow dusted over with minute 

 dusky specks visible under the magnifying glass.

Variation. — An adult specimen in British Museum (No. 92. 1. 11. 

 18) collected by Hoist in Tsu-shima, October 6, 1891, has a somewhat 

 longer series of vomero-palatines, inasnuich as the length from angle 

 to angle is about two-thirds the width of the tongue. The propor- 

 tions of head and body are nearly the same — viz, snout to gular fold 

 16 mm. and gidar fold to vent 52 mm., or the latter distance three 

 and one-fourth times the former. The tail, however, is much shorter, 

 being less than the body without head. The color (in alcohol) is 

 also difl'erent, being above yellowish brown with numerous obscure 

 dusky spots; underneath uniform pale brownish, this pale effect 

 being produced by a uniform dusting of minute, round, yellowish 

 specks on a dark brownish gray ground. The coloration of this 

 species is usually described as more strongly marbled and variegated 

 than the above individuals, in fact much more like the two speci- 

 mens descril^ed above as //. nsevius. It should he noted, however, 

 that the colored reproduction of the drawing from a living specimen 

 in Schlegel's "Abbildungen," pi. xl, figs. 7 and 8, shows an animal 

 uniforndy dark brown above, more grayish and ])aler underneath. 



KcinarlxS. — Tliis s])ecies dilTers chiefly from //. na:vius in the shorter 

 body with longer limbs, so that the fingers and toes overlap on the 

 side, and in the more pointed tail, which is compressed all the wa}" 

 from the ])ase and keeled and finned above and below toward the tip.
