The specimens correspond in man}'- respects with Moc- 

 qitard's description, but differ in several points. I was there- 

 fore very doubtful, whether they shoiild be assigned to this 

 species or regarded as a new one. In a letter to Dr. Mocquard 

 I gave a brief description of them, asking him for a comparison 

 with the type-specimen, and he kindly answered that, in his 

 opinion, my specimens are true C. calcaratus. 



The characters in which my specimens, which are very well 

 preserved, differ from Mocquard's description are as follows: 

 From the posterior margin of the eye-opening there extend 

 two distinct folds, viz. one to the shoulder and another to the 

 groin, running along the sides of the body; the upper surface 

 is distinctly tuberculated; in the small specimen the canthus 

 rostralis is angular, and in both the nose is acuminate, not 

 rounded; the tips of the fingers and toes are rounded; the tarsal 

 tubercle is situated almost centrally between the distal point of 

 the tibia and the large inner metatarsal tubercle; there is no 

 trace of an outer metatarsal tubercle. 



The colour agrees fairly well with that of the type-specimen. 

 The large specimen differs in having distinctly marked dark 

 spöts on the anterior part of the light belly, and in both there 

 is a narrow median light line on the throat. In the smaU spe- 

 cimen the sides behind the fold to the shoulder and below the 

 lateral fold are chocolate-brown, bordered above with a black 

 margin, sharply defined from the light upper parts of the loin 

 and extending along the thighs like a dark stripe.
