of the neck, whicli gradually disappears in tlie dark line of the sides. 

 This band to the last labial is bordered above by a yellow stripe, which 

 does not join the yellow stripe on the side of the neck. It is dark 

 brown, bordered above. Head above light brown, with two yellow 

 brown -bordered parietal spots such as are usually jiresent in water 

 snakes. 



Measurements. — Total length, 385 mm. ; tail, 99 mm. 



This species approaches e({ually several species, but differs from all 

 others. It combines a long body and short tail, with large and few 

 ^inferior labials, as in R. fulviceps^ which is a long- tailed species, with 

 a different coloration. 



We owe tliis species to Sumichrast, who states in his notes that he is 

 not sure of the locality where he obtained it, but thinks it is Orizaba.

Habit moderately slender ; tail 3.2 times in total length ; head distinct, 

 elongate, oval. Scales very thin, without scale-pores, in seventeen lon-
