reaches between tlie nostril and the tip of the snout.^ Skin 

 on the back, on the sides, and on the upper parts of the 

 hind limbs tuLercular ; on the back and on the hind limb 

 the tubercles are small and scattered, on the sides large and 

 partly fused together in irregular large warts. On each side 

 of the back runs a narrow but distinct glandular fold from 

 behind the eye to the outer end of the sacral vertebra; traces 

 of such folds are also to be seen on the sides. The upper 

 parts of the head and of the före limbs, and the whole under- 

 side are perfectly smooth. 



Brownish grey above with small black döts, especially 

 on the tubercles and on the folds; the under surfaces of hand 

 and foot blackish brown. All other parts: the sides of the 

 body, the lips, the whole underside and concealed parts of 

 limbs brownish black with large irregular white spöts; on 

 the belly, the under parts of thighs, and to some extent also 

 on the sides, the white colour prevails, so that one may say 

 that they are white with a netAvork of blackish brown. No 

 cross- bars on the limbs. Tympanum greyish brown with a 

 broad dark margin. 



The specimen is a male (no external vocal sacs). 31 ea- 

 surements: Length from nose to vent 115 mm, length from 

 nose to hind margin of tympanum 42 mm., length of nose 

 20,5 mm. Diameter of orbit 11 mm, diameter of tympanum 

 8 mm; breadth of head at the angle of mouth 46 mm. Length 

 of före limb (along the posterior surface) 67 mm; length of 

 femur 61 mm, length of tibia 58 mm, length of foot with 

 4:th toe 87 mm. 



On account of the great size and the large tympanum 

 the species comes near to L. pentadactyhis Laur. but it differs 

 distinctly from this one especially by the quite different ap- 

 pearence of the skin and by the colour. Nor can I find it 

 identical with any species with dorsal folds. 



^ The usvial way of measuring the length of the hind limb in com- 

 parison with that of the body: »the hind limb being carried forwards along 

 the body etc», is here, as I have also found in many other cases, rather 

 unsuitable, if one will not get the risk of breaking the tibia at tlie knee. 

 I find it much better to mark off the length of the tibia with a pair of 

 compasses, the limbs of the animal being pressed to the body in usual 

 resting position as on the plate. It may not be difficult to place the limbs 

 in this natural situation, and the measurement cannot then be taken in 

 more than one manuer, which is not always the case in the usual way of 

 measuring.
