wider than the widest part of supraocular; parietals one and 
two-thirds times as long as wide, forming a suture for about 
four-fifths their length, truncate behind; nasal large, irregular, 
partially divided, posterior part largest, much higher than ante- 
rior part; an elongate loreal, more than twice as long as wide, 
entering orbit; one preocular; supraocular much shorter than 
frontal, much wider posteriorly than anteriorly ; two postoculars, 
upper square, touching parietal, lower higher than upper; two 
anterior temporals, followed by three, then by four; the last 
superior temporal much the largest; three temporals bordering 
parietals; nine upper labials, fourth and fifth entering orbit; 
mental much broader than deep; two pairs of chin shields, ante- 
rior much longer and wider than posterior, five labials touching 
anterior; ten lower labials, the last lower and upper labial not 
well differentiated; eye moderate, its diameter nearly equal to 
its distance from nostril; pupil vertically elliptic; scales in 
seventeen smooth rows, without apical pits; ventrals, 220, 
keeled laterally; anal single; subcaudals, 121, in two rows; head 
distinct from body, flattened; tail very slender. 
Color in life-—Snout black, growing brown on parietals; a 
V-shaped white mark bordering the posterior edge of frontal: 
_a black mark begins on posterior edge of parietals and continues 
on neck; a black mark below eye continues back to eighth labial; 
lip light, flecked with darker; chin and neck white; anterior part 
of lower lip flecked with dark; body with fourteen elongate, 
irregularly edged, black, saddlelike blotches which are narrowed 
laterally, reaching the edges of the ventrals; these blotches 
cover twelve scales longitudinally, and are separated by smaller 
white rings which are four to five scales long medially but 
cover as many as eight scales laterally, the last two white rings 
with black spots; tail with nine black blotches which encircle 
tail toward its end; belly white.

Remarks.—The species here described fails to agree with the 
generic characters assigned to Dryocalamus by Boulenger, as 
follows: There are seventeen scale rows instead of thirteen to 
fifteen; no apical pits on the scales; the dentition of the max- 
illary differs in that there are eleven or twelve teeth, increasing
