Report, p. 14. 



Head elongated, more or less depressed forward. Frontal plate 

 pentagonal, much broader anteriorly than posteriorly. Rostral broad. 

 Anteorbitals two ; postorbitals three. Loreal trapezoidal. Dorsal rows 

 of scales twenty-nine to thirty-one; three outer rows smooth. Tail 

 one-sixth or one-seventh of total length. Frontal black bar well marked. 

 Postocular vitta extending over the last upper labial to the angle of 

 the mouth. Color of body whitish yellow on the sides, reddish yellow 

 above, with a dorsal series of subquadrate blotches, fifty to seventy in 

 number, from the head to origin of the tail, and proportionally smaller 

 than in any other species. The blotches of the two adjoining series not 

 confluent with those of the medial one. 



Head elongated, subelliptical, more or less depressed anteriorly. 

 Parietal plates much longer than broad, longer than either the frontal 

 or superciliaries. Frontal pentagonal, concave laterally, tapering; 

 length greater than the width of its anterior margin. External pre- 

 frontals sometimes longitudinally divided into two plates. Internal 

 prefrontals elongated, very narrow posteriorly, sometimes also sub- 

 divided, liostral broad, not separating the prefrontals. Nasals equal 

 in size; nostrils Intermediate and nearer to the frontals than labials. 

 Loreal not very large. Inferior anteorbitals small, and situated between 

 the fourth and fifth upper labials. Postorbitals nearly equal in size, 

 and generally contiguous to the anterior ones, thus excluding the labials
