of several scales; the spots in the lower series are larger. Intervals 

 between the lower series of spots occupied by reddish-brown scales, 

 in shape and color somewhat resembling the dead leaves of the hem- 

 lock {Ahies canadensis) . Intervals between the upper series olivace- 

 ous-brown, more or less blended with the black. Beneath uniform 

 greenish-white, with the bases of the scutellae black, as are also the 

 scales on the exterior rows ; this color, however, rarely shows beyond 

 the margin of the incumbent scales. 



In one specimen, which is much larger than the others, the dorsal 

 spots form a rather narrow margin to the broad dorsal stripe, and are 

 more or less confluent with the ground color. The space between the 

 lower row of spots is pale reddish. Dorsal scales in nineteen series. 

 Ninety spots from head to anus. 



The characters are very strongly marked, and easily recognized.
