CoRONELLA MULTiciNCTA. Allied to the " Couleuvre a capuchon" 

 but has the muzzle much shorter and rounder ; it differs also in the 

 distribution of the colours. 



The head is broad, the eyes very small, the muzzle very short 

 and blunt. 



The head is gray, finely and closely marbled, and dotted with 

 black ; a ring of which colour encircles the neck. The ground 

 colour of the trunk above is pale cinereous gray, barred with trans- 

 verse marks of black, broadest in the middle, and having a disposition 

 to assume the arrow-head form ; they unite with the black of the 

 abdomen alternately, so that their direction across the back is not 

 directly transverse but obliquely so.

CoRONELLA MODESTA. Head Small ; muzzle short, but moderately 

 pointed; eyes small. Scales of upper parts smooth and small ; uni- 

 versal colour yellowish gray. A black band passes from eye to eye ; 

 a second crosses the occiput ; and a third of a more decided tint en- 

 circles the back of the neck. In a specimen from Trebizond, pro- 

 Cured by K. Abbot, Esq., the marks on the head are more obscure. 



Length of head and body 9 inches.

CoRONELLA PULCHRA. Head loug, flat, and pointed at the muzzle ; 

 eyes moderate. 



Scales small and smooth. 



General ground colour ashy gray ; the head above beautifully 

 marbled and mottled with black ; an irregular mark crosses each 

 superciliary plate and extends upon the vertical ; and a mark of the 

 same character traverses each occipital, and extends upon the sides 

 of the occiput. A black mark runs below the eye to the margin of 

 the lips, and a second to the angle of the mouth ; a series of black- 

 ish spots begins on the back of the neck, and runs down the back, 

 where they become larger, and often broken into a double alternating 

 series ; a line of smaller and deeper black spots runs along each 

 side, and the upper margins of the abdominal plates also are irregu- 

 larly mottled with black. The plates of the abdomen are minutely 

 and obscurely freckled with dusky black.

VxPERA EuPHRATicA. Allied to Vipera elegans, but differs in the 

 disposition of the plates around and between the nostrils, and in the
