Rostral well developed ; pnefrontals more than half as large as 
postlVontals, the suture between the former but little shorter than 
I hat between the latter. Vertical large, pentagonal, the anterior 
margin convex, lateral edges converging slightly behindi posterior 
margins meeting at n right angle. Each occipital ii both longer md 
broader tban the verticaS, and is rounded behind. 
Lorpal well developed . about as high as broad. Two (or three) 
preeoeulars, the upper double the size of the lower ; two [jostoculars ; 
temporals 2+.1, the upper anterior temporal shield in contact with 
both postocuiara ; two elongate temporals along the outer side of 
each occijjital. Upper labials 8, the seventh excluded from the 
margin of the Hp, the fourth and fifth (or on one side the fifth oulv) 
entering the orbit. Two pairs of chin-ahields, the posterior but 
little shorter than the anterior. 
Ventral shields 17-^; anal undivided; suhcaudals in 50 pairs, 
with a long terminal scale. 
Back grey, with eleven dark-brown cross bands or large traoa- 
verac spots on the body, and four on the tail, all having very 
irregular zigzag margins, and being, where widest, about half the 
breadth of the interspaces ; the latter arc slightly spotted and 
mot lied with brown. On the head there i:* a broad dark cross band 
between the anterior parts of the eye-orbits on the front part of the 
vertical and on both pairs of frontals, and continued below the eye on 
the fifth and sisLth supralabials. Behind this is a pointed elongated 
arrowhead-shaped dark mark, joining the anterior band on the 
vertical shield, and bifurcating behind on the neck ; there is also an 
obli(pic band just behind the angle of the mouth. Belly whitish, 
with small quadrangular <i]ark spots on the aides of ever^ second or 
third ventral. 
A single specimen is sent ; it is only 8 inches long, the tail mea-- 
goring 1^. 
This is another species of the peculiar group of Stmotes com- 
prising S, cochinekinensis. S. hrevicauda S. caleni/er, and S. an- 
corftlh ^. It is distinguished from all by having the seventh supra- 
labial shield shut out of the lip-margin, and from all but the first 
by having twenty -one rows of scales. The coloration, too, differs 
somewhat from that of S. eochinekmensiSt in which the lower parts 
are white.
