Differs from the preceding in the absence of caudal spines and 

 the presence on the back of large, round, obtusely conical tubercles 

 forming two irregular longitudinal series. The ear-opening is still 

 smaller than in D. spinigerus ; and there are only ten to twelve 

 labials. The head is not black- speckled, but has dark undulated 

 longitudinal lines, a lower passing through the eye, and an upper 

 meeting its fellow on the snout.

Head short, very convex ; snout rounded-acuminate, measuring 

 the diameter of the orbit or the distance between the eye and the 

 ear-opening ; latter rather small, round. Body short ; limbs 

 moderate. Digits short, depressed, with small apical dilatation, 

 inferiorly with a series of large transverselj- oval tubercles, some 

 of them breaking up into two rounded tubercles ; the extremity 

 of the digit is raised and bears inferiorly two roundish plates 

 separated from the large tubercles of the basal part by three or four 

 rows of small granules. Upper surfaces covered with uniform small 

 granular scales. Ilostral four-sided, twice as broad as high, with 

 median cleft above; nostril pierced between the rostral, the fiust 

 labial, and five or six nasals, the anterior or upper largest and 

 generally in contact with its feUow, the others granular ; ten or 

 eleven upper and as many lower labials ; mental trapezoid, a little 

 larger than the adjacent labials ; no chin-shields. Abdominal scales 

 granular, scarcely larger than those on the upper surfaces. Tail 

 short, swollen, root-shaped, with rings of uniform small squarish
