Lophocalotes interruptus, GUnih. I. c, pi. xxxvii. fig. A. 



Head large, swollen below the ears, very distinct from neck ; 

 snout longer than the diameter of the orbit ; tympanum much larger 

 than the eye-opening. Upper head-scales irregular, faintly keeled ; 

 supraorbital scales small, strongly keeled, bordered inwards by a row 

 of enlarged scales ; three large scales in a series on the temple ; a 

 small slightly prominent tubercle behind " the supraciliary edge and 

 another on each side of the nape ; seven upper and eight lower 

 labials. Gular scales subrhomboidal, smooth or feebly keeled, those 

 on the median line the smallest, the lateral ones larger than the 

 ventrals. Nuchal crest formed of lanceolate spines not quite as long 

 as the diameter of the tympanum ; dorsal crest not continuous with 

 nuchal, formed by about fourteen triangular spines, only every alter- 

 nate median scale being modified into a spine. Dorsal scales large, 

 rhomboidal, rather feebly keeled, the points of the upper scales 

 directed upwards and backwards ; ventral scales smaller than 

 dorsals, strongly keeled. Limbs above with subequal keeled scales, 

 some of which are spinose ; fourth finger and toe slightly longer 

 than third ; the adpressed hind limb reaches hardly the tympanum. 

 Tail compressed at the base, covered with equal keeled scales ; its 

 length equals nearly once and three fourths that of head and body. 

 Green abore, with rather irregular yellowish markings on the head 

 and body and cross bars on the limbs.
