THE 13ATRACIIIA OF NOllTII AMERIOA.

is divided centrally by a longitudinal dark brown line, beginning as a 

 few dots, on the top of the head, then uniting into a continuous stripe, 

 which extends to the rumi), and is a little narrower than, or about equal 

 to, the two light stripes into which it divides the color of the back. 

 The light dorsal stripe is bordered on each side by a continuous dark 

 stripe well defined on the upper edge. The under parts are yellowish 

 in alcohol, distinctly mottled or vermiculated with brown in about 

 equal proportions. In the present specimen there is no distinct light 

 line below the brown of the sides, which breaks up gradually below, 

 passing into the reticulation described. There is a single light spot in 

 the darkest part of the sides, one to each intercostal section. The sides 

 of the tail are dark brown, with vertical light bars analogous with the 

 white spots just described. 



In other specimens the dark brown which borders the yellowish of 

 the back is sharply defined on its lower margin, also forming a con- 

 tinuous line of variable diameter, with a series of white spots, one to 

 each space, between the costal furrows. Below this again is another 

 continuous, quite well-defined light stripe, after which succeeds the 

 mottling described. In this case there are three black stripes, one 

 median dorsal, and two lateral; and four light stripes, two median, of a 

 brownish-yellow color, and two lateral, whitish in alcohol. 



The comparison of form has already been made with S. longlcaudus. 

 The color differs essentially in the vermiculation, with brown beneath, 

 instead of being perfectly immaculate. If the varieties of 8. lonrjicandus 

 having three series of dorsal dots had these united into continuous 

 stripes there would be some resemblance to the present species. Such 

 is, however, never the case. The tail, instead of being yellow, with 

 narrow vertical dark lines, is dark, with narrow vertical light ones. 



I have found a cirrigerous form of this species in North Carolina.
