SITANA MINOR. 135 



tapering. Head covered with small, keeled scales ; labial shields numerous ; a series of larger 

 scales on each side of the chin. A pair of small canine teeth in each jaw ; tongue elongate, 

 not notched ; nostril small, directed outwards, in a very small shield ; eyelid scaly ; tympanum 

 smaller than the orbit. The male is provided with a very large, subtriangular gular appendage, 

 which extends on to the belly ; it is covered with large square scales regularly arranged ; it 

 can be folded up like a fan, and in this state it is scarcely visible. The female has no trace 

 of this appendage. 



Sitana is confined to Western India and to Ceylon ; only two species are known : — 



The hind feet extend to the orbit S. pondiceriana. 



The hind feet extend to or beyond the extremity of the snout . S. 'minor. 



Sitana pondicebiana. 



Sitana ponticeriana, Cuv. Regne Anim. Dum. ^- Bibr. iv. p. 437. 



The fore limb does not extend on to the vent, if laid backwards ; the hind limb reaches 

 to the orbit, if laid forwards ; the lower thigh is rather shorter than the foot (measured from 

 the heel to the tip of the longest toe), the length of which is only three-fourths of the 

 distance between the shoulder and hip joints. Brown, with a series of dark spots along the 

 middle of the back, the spot on the neck being the darkest ; a whitish band along each side 

 of the back. Gular appendage tricoloured — blue, black, and red. 



This species attains to a length of 8 inches, of which the tail takes 5 inches. It appears to 

 inhabit more northern parts of India than the following. 



Sitana minor. (Plate XIV. figs. A, A'.) 



Sitana ponticeriana, Jerd. Journ. As. Soc. Beng. xxii. p. 473 (not Cuv.). 



The fore limb extends beyond the vent, if laid backwards ; the hind limb to or beyond the 

 extremity of the snout, if laid forwards ; the lower thigh is considerably shorter than the 

 foot, the length of which is more than the distance between the shoulder and hip joints. 

 Brownish, with a series of rhomboidal dark spots along the back, the spot on the neck beftig 

 the darkest ; a whitish Ime along each side of the back. Gular appendage tricoloured — blue, 

 black, and red. 



This new species is closely allied to the other, but readily distinguished by its proportion- 

 ally much longer limbs, — the foot of a *S^. minor, the body of which measures 2 inches in 

 length, being almost as long as that of a S. pondiceriana, the body of which is 3 inches long. 

 Moreover it remains smaller, full-grown specimens measuring 7 inches, of which the tail takes
