but have the normal 9 labials with fourth, fifth, and sixth entering 

 the orbit on the left side. In one snake (No. 49386) the fifth upper

 lower postoculars to form single scales. The largest snake measures 

 710 (473 + 237) mm. and the smallest 336 (231 + 105) mm.

 mediate between C. hoplogaster and C. negledus in that posteriorly 

 its ventral scutes show traces of a keel; anteriorly they are typical.

 and smallest 486 (356 + 130) mm.

Mid-body scale rows, 15; ventrals, 152 to 170; subcaudals, 98 to 

 117; the labials in 21 of the 27 snakes are normal — that is, have 8 

 upper labials, of which the fourth and fifth enter the orbit— one has 

 7 with third and fourth entering the orbit ; another 7 with fourth and 

 fifth on the left side; and 9 with the fifth and sixth on the right side; 

 yet another has 9 with fifth and sixth on both sides; and No. 42063 

 is normal on the right side but with 8 labials on the left, of which the 

 fifth and sixth enter the orbit. Numerous minor variations occur in 

 this series, such as division or fusion of the ventral scutes. No. 

 40988 presents a peculiarity in having its two last ventrals fused into 

 a single shield except for a small suture remaining in the middle.
