Puellttla, nobis, n. s. Aspect of a Hemidactylus, but wifch no 

 dilated palette on the toes, which are distinctly ribbed excepting on 

 the unguinal phalanges. No femoral or prse-anal pores, but a large 

 raised glandular space at the base of the thighs underneath, divided 

 by a slight median groo ve on the anterior half, which deepens to 

 form a large glandulous cavity on the posterior half, the labia of 

 which are covered with scales larger than the rest ; this structure 

 being much less developed in the female sex. A very remarkable 

 feature, í'or a Gecko, consists in a distinct rudimentary dorsal crest ; 

 and there is also a lateral fold of skin from the fore to the hind limbs, 

 dividing the scales of the back from those of the belly, and another 

 such fold margining the thiglis anteriorly. The pupils of the eyes 

 cióse vertically. 



P. rubida, nobis, n. s. Back and limbs above covered with mi- 

 nute tubercles, and also thickly studded with tubercles of a larger and 

 uniform size, the former requiring a lens for their easy detection ; on 

 the tail are few only of the larger kind, and those disposed in trans- 

 verse series on its basal half: scales of the head minute and uniform, 

 those of the throat very minute, and those of the lower-parts small 

 and uniform, save on the borders of the glandulous fissure, where they 

 are a litfcle larger ; on the lower surface of the tail the scales are also 

 larger. Bordering the lower labial shields in front are four large 

 plates, the medial of which exceed the outer in size. Colour of the 

 fresh animal very ruddy, a hue which soon disappears by exposure to 

 the light in spirit. In the stronger-marked specimens a dark line 

 passes backward from the eye, and meets its opposite upon the occi- 

 put ; this V-like marking being succeeded by one or two others like it, 

 and there are irregular narrow transverse bands throughout, com- 

 posed of black tubercles interspersecl among the rest, and a series of 

 broad dark annuli on the tail. Length about 5 in., of which the tail 

 is half. A common species at Port Blair. The young, 2 in. long, 

 show some white specks on the neck, and the labial plates are alter- 

 nately dark brown and white. This is also seen in the adults, but 

 less conspicuously.
