37. GECKO. 185 



vertical diameter generally less than half the diameter of the orbit. 

 Body and limbs rather more elongate than in 0. verticiUatus ; digits 

 free. The scales on the head and back similar to those of Q. vertir- 

 cillatus, but smaller ; upper labials twelve to fourteen, first entering 

 the nostril ; lower labials ten to twelve, gradually decreasing in size ; 

 chin-shields three to five on each side, smaller than the labials, the 

 inner pair generally longer than the mental. Back with ten or 

 twelve longitudinal series of mamilliform tubercles. Throat covered 

 with exceedingly small granules ; ventral scales larger than in O. 

 verticiUatus. Prseanal pores eleven to sixteen altogether. Tail like 

 that of O. verticiUatus, but the scales on the upper surface much 

 smaller, the annuli being composed of ten or eleven transverse 

 rows of scales ; the large scales on the lower surface of the tail are 

 much dilated transversely, forming generally two symmetrical series. 

 Brown or brownish grey above, marbled with darker, with or without 

 transverse rows of whitish spots, — a character of the young in this 

 and the preceding species, but which may here persist throughout 

 life ; sometimes a linear, A-shaped dark brown mark on the head ; 

 tail annulate with darker and lighter ; lower surfaces whitish, 

 generally dotted or variegated with greyish.
