. Bulletin - United States National Museum. Science. THE 13ATRACIIIA OF NOllTII AMERIOA. 171 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
