the base, ending; in a l)hint point, upper and lower edge compressed, 

 ridge-like; vent a short longitudinal slit with transverse folds or 

 papilhr along the edges which are not raised or swollen; gular fold 

 a slight depression; the whole body, including throat and legs above 

 and below^ roughly granulated or tuberculated, the only smooth 

 places being the lips, underside of hands and feet, and the lower edge 

 of the tail. Color (in alcohol) above and below dark "mummy- 

 brown," the bony ridges on head and back, as well as the two series 

 of knobs on each side of the back, pale, like old ivory; underside of 

 hands and feet, as well as lower edge of tail, yellowish.

Variation. — The specimen described above being only tlie second 

 one known, it is obviously impossible to indicate the extent of indi- 

 vidual variation in this species or even of sexual differences, as 

 both specimens appear to be females. There are several points in 

 which the two specimens differ, however. Thus, in the tj^De the 

 vomero-palatine series of teeth converge somewhat about the middle 

 before the final flaring divergence. In the proportions there is, 

 moreover, tliis difference, that in the type the tip of the toes reaches 

 the elbow of the fore leg when the legs are pressed against the side; 

 the length of the tail of the type is also proportionally greater. 

 That the type is said to have an oval tongue and to be of a black color 

 are differences of but slight consequence, but it is rather remarkable 

 that the type does not appear to have the inner row of dorsal knobs 

 differentiated to such a degree as to call for special mention in the 

 original description. 



Habitat. — The type of this species was discovered by Mr. Hoist in 

 Okinawa Shima, in 1892, and is in the British Museum. A second 

 specimen, the one described above, belongs to the Science College 

 Museum in Tokyo, the only ones thus far on record. This latter 

 specimen is from the same locality as the type.
