bright yellow, almost forming a series of yellow transverse bands on 

 the side and between each of those above ; one or two of the scales 

 are longitudinally margined with a like colour. The under surface 

 of the posterior five sixths of the body is much finely spotted or 

 punctulated with black, and the last sixth is almost wholly black, as 

 is the under surface of the tail. This specimen has nineteen rows 

 of scales, pointed prefrontals, only two anterior oculars and three 

 postoculars ; but it is evident, from the way in which the super- 

 ciliary shield is prolonged down behind the eye, that it is confluent 

 with the fourth postocular ; eight upper labials, the fourth enter- 

 ing the orbit. 



This species is recorded by Prof. Filippi in his work on Persia.

GONYOSOMA DORSALE, 11. Sp. (Fig. 9.) 



Rostral rather prolonged on to the top of throat. Head elon- 

 gately oval and rather pointed. Anterior frontal quadrangular, 

 rounded in front, nearly as large as the posterior frontals. Loreal 

 subquadrangular. Two anterior oculars, the upper one large, and 

 reaching the vertical; the inferior ocular evidently a separated 

 portion of the fourth and fifth labials. The fourth labial also 

 divided below the posterior half of the loreal. Fifth and sixth 

 labials entering the orbit, the sixth prolonged backwards before 

 the seventh labial, which is the largest. Two posterior oculars ; 

 vertical rather elongate. Lateral margins rather deeply concave!

Gonyosoma dorsale. 



Occipitals rather large, and nearly oblong, abruptly transversely 

 truncated behind. Temporals 2 + 3 + 4 = 9. A line of elongated 

 temporals along the occipitals, and another similar line along the 

 labials. The two anterior shields of each of these lines in contact, 

 the remainder of the lines enclosing three other shorter temporals. 

 Scales smooth, long, lanceolate, with an apical groove, in nineteen 

 rows. Ventrals keeled, prolonged up the side, 227; caudals 107. 

 Anal bifid. 



Pale yellowish green above, with a bright pink longitudinal band 

 from the posterior extremity of the vertical on to the base of the tail, 

 where it disappears. Under surface bright yellow. Area round the
