 larger than the females. 



Male.—VvV&r^ surface of a pale rusty-brown ground-colour, 

 intermixed with ashen-grey, which in some specimens forms four 

 to five indistinct transverse bands across the back for its whole 

 length. Middle of throat, chest and under-surface ot imbs 

 black A lanceolate black gular mark is not confluent with the 

 black shading of the chest. On each side of the vertebral region 

 extends a continuous lozenge-pattern marked out in pale reddish- 

 brown, each lozenge containing darker markings in the centre. 

 In other instances the elements of the pattern are not con- 

 tinuous and of a rounded shape approximating to ocelli. JNeck 

 marked with two to four fairly regular alternate bands of dark 

 yellowish-brown, which in some specimens extend along the back, 

 where they disappear. Sides with irregular dark-brown or black 

 markings disposed on a ground of yellow or yellowish-brown, the 

 dorsal ashen-grey stripes also extending into this region. 

 "Limbs and tail dark rusty-brown, transversely crossed with 

 indistinct paler bands. Under-surface yellowish. In A scut- 

 ulatus the chest marking is more elongated, and extends as fai a 

 the junction of the hindlimbs. Under-surface of the tail 

 uniformly light-coloured. The male with hfty prie-anal and 

 femoral pores, forming an uninterrupted series on each side, 

 absent in the female.

 T^emaZe.— Very similar in markings to the male, but in most 

 specimens the chain of lozenge-shaped lateral markings is broken 

 up into a series of light-edged ocelli ; these are generally irregu- 

 larly roundish or oval and often confluent ; m some specimens 

 they assume the shape of a series of figures of 8. Under-surface 

 uniformly light-coloured, the black markings on throat and chest 

 very faint or, on the latter, totally absent.
