Eyes, rather small, round ; dark ash coloured, with a round white 

 pupil. 



Scales, smooth, not keeled, generally oval-shaped, and in 29 series. 



Ventral plates proper, (from the throat to the anals and including 

 throat plates,) 153. Pra>nasal plates 4, in pairs, — or in other words, 

 two bifid plates. Post-nasal plates 7, in a transverse series of 4 and 

 8. Sub-caudal plates proper 100, in pairs. Total lower plates of 

 under-part of body, 264. 



Colouring and markings. — -Markings on plates on the top of the 

 head of a sort of puce, or olivaceous mouse-brown, or a muddy 

 olive chocolate colour. A narrow yellowish white curved line runs 

 longitudinally along the centre of each of the occipital plates, and 

 extends to the nape. Anterior upper labials marked with dark 

 blotches. A broad, dark olivaceous brown, narrowly-black-edged, 

 stripe, runs along the cheeks, from the posterior upper labials, to 

 beyond the gape, backwards, as far as the side of the neck. A yel- 

 lowish-white stripe runs from the back of the eye to beyond the 

 occipitals, as far as the back of the neck, on each side, posteriorly, 

 and is again produced anteriorly as a narrow streak in front of the 

 eye, then running round across the prae-frontals, (just behind the nasals) 

 to meet the corresponding line on the other side ; the angular curve 

 of the streak as it crosses the front of the head, becoming lineally 

 attenuated. There is a muddy olive chocolate coloured, longitudinal 

 stripe on each side of the nape of the neck, on the scales which lie 

 immediately at the back of each of the occipital plates, which unites 

 anteriorly with the dark colouring of the head plates. A longitudinal 

 broad stripe of the same dark colour, occupies the centre of the nape, 

 which unites anteriorly with the dark colouring of the central head 

 plates, and blends posteriorly with a large broad, oblong shaped, 

 centrically narrowed, muddy olive-brown coloured, and narrowly 

 black-edged blotch, occupying the whole of the back of the neck. A 

 transverse, irregularly shaped, narrow, yellowish space, or band, runs 

 off transversely, laterally on the neck, from each side of the dark nape 

 mark, and divides the large dark blotch on the back of the neck, — on 

 each side, — from the dark cheek stripe, and unites below with the 

 yellow of the sides of the neck. A dark line runs longitudinally 

 through the pra>oculars and nasals. Vertical shield of the same dark
