 tened; rostral small, barely visible from above, about as high as 

 wide ; suture with first labial very short, that with nasal about 

 twice as long as that with internasal ; latter small, bordering 

 nostril above, very much wider than deep, pointed laterally above 

 nostril ; prefrontals large, two and a half times as long as inter- 

 nasals, about as wide as deep, not touching labials; frontal a 

 little longer than broad, narrowed rapidly behind to a point, much 

 shorter than its distance from end of snout, about equal to its 

 distance from rostral ; parietals longer than wide, longer than 

 frontal but of nearly equal width, in contact with only the upper 

 postocular; nostril large, pierced between 2 nasals, with inter- 

 nasal forming part of upper rim; anterior nasal largest, widest 

 where it borders rostral, tapering tovv'ard nostril ; posterior very

 to, or a little less than, its distance from mouth. 



Color in alcohol. — A large, median, black stripe from frontal 

 to tail, covering three whole rows and two half rows of scales ; 

 behind supraocular begins a white line, covering two half rows 

 of scales, extending to tail ; behind eye a second black stripe 

 begins and continues to tail, one whole and two half scales wide ; 

 below this, a white line one and a half scales wide ; toward latter 

 part of body there is a dotted line along the middle of the outer 

 scale row; anteriorly the two black stripes merge in a band of 

 black crossing head, involving the eyes but not reaching the 

 mouth; a whitish band (red in life) in front of" this ; rostral dark;
