lateral and dorsal cross bars are about one-balf to one scale 

 wide. Not infrequently the lateral bars become united with 

 the ventro-lateral spots. Each scale of the dark areas is light- 

 ened basally, the light grading distally very gradually to the 

 darkest shade at the distal border of the scale. On the scales 

 that take part in the light transverse bands the change from 

 light to dark is not gradual, but sudden and sharply defined. 

 The series of dorsal, lateral, and ventro-lateral light bars tend 

 to be connected in the chain-pattern style of L. getulus. The 

 under side is largely light, but checked with dark chiefly at the 

 sides. Head markings like L. getulus; a light spot occupying 

 the centers of the internasals, nasals, loreals, oculars, and temp- 

 porals ; transverse light bars anteriorly on prefrontals ; a light 

 spot anteriorly and medially on supraoculars and frontal ; on 

 parietals a light spot at each angle and one or two near the 

 common suture ; labials with the anterior and posterior, or with 

 only the posterior, edges dark ; rostral and mental edged pos- 

 teriorly with dark ; chin shields and gulars mostly light. 



General Description : Besides the type, several specimens 

 have been available for study, and from them the following 

 description has been prepared. Ventrals, 211-226; subcaudals, 

 42-53; supralabials usually 7, sometimes 8; infralabials, 9 or 

 10; oculars, i and 2 ; temporals, 2-|-3-f-4 ; posterior chin shields 

 about equal in length to the anterior, parallel and sometimes 

 separated by a scale ; loreal rectangular, higher than long or . 

 about as high as long, in one specimen fused with the posterior 

 nasal. Maximum number of scale rows usually 23, sometimes 

 21 ; formulae 23-21 ; 23-21-23-21-19 ; 21-23-21-19; 21-19. Tail 

 .100 to .150 of total length. Pattern similar to L. getulus, ex- 

 cept that the transverse light bands on the back arc about 

 double the number on the latter species, varying from 46 to 75. 

 with an average of 64. In distinction from L. getulus the
