Spec. Char. —Body slender; head short; branchial arches almost vertical, their pectination coarse and distant. General 
color reddish brown, marmorated and blotched, (almost vermiculated,) obscurely with blackish; quite distinctly on the 
belly. Length 6 £ inches. Head and body about 3£. 
This species differs from S. lichenoides 1 in the variegation of reddish brown and dark brown 
in nearly equal proportions. The body is more slender; the branchial arches more perpendicular 
to the axis of the body. The feet are quite well developed. The form is much more slender 
than in S. mexicanus , the limbs stouter, the color quite different.
