178 GECKONID^. 



General proportions of B. trachyrhynchus. Head oviform ; snout 

 longer than the distance between the orbit and the ear-opening, 

 once and a half the diameter of the orbit ; forehead concave ; ear- 

 opening narrow, horizontal. Body and limbs moderately elongate, 

 not much depressed ; digits broadly dilated, not very unequal, their 

 border very distinctly denticulated, half- webbed; the web very 

 short, though distinct, between the two outer toes ; limbs bordered 

 by cutaneous folds, most developed on the anterior side of the fore 

 limbs and on the posterior side of the hind limbs ; other cutaneous 

 folds below the rami mandibulae, on the sides of the neck, and from 

 axilla to groin ; the latter feeble ; throat with irregular cross folds. 

 Upper surfaces covered with very small equal granular scales, scarcely 

 larger on the snout ; gular scales minute, granular ; abdominal 

 scales very small, flat, juxtaposed. Rostral twice as broad as high ; 

 nostril pierced between the rostral, the first upper labial, and six or 

 seven small nasals ; thirteen or fourteen upper and twelve or thirteen 

 lower labials ; mental elongate wedge-shaped, as long as the adjacent 

 labials, which it separates ; no regular chin-shields, but a few larger 

 scales passing gradually into the minute granules of the throat. 

 Male with three short series of femoral pores on each side ; these 

 do not extend beyond the inner half of the thighs, and are separated 

 from the corresponding series on the other side ; altogether seventy- 

 nine pores. Grey above, whitish beneath, marbled with grey, forming 

 transverse bars on the belly.
