. Bulletin - United States National Museum. Science. EASTERN PROVINCE INTERIOR REGION SPECIES. 241 The lingual membrane (T. M. U. S., V, Plate IV, Fig. O) is arranged as usual in the Helicidce. Morse'counted 115 rm. 259. rows of 5G-1-5G teeth; another membrane gave 49-1-49 teeth, with 22 perfect laterals ; I hav^e myself counted 5G-1-56 teeth, with 11 perfect laterals. The central teeth have a very jaw of t. dorsaUs. long, narrow base of attachment, widening towards the lower margin, which is excavated. There is a line of reinforcement running parallel to the lower edge and for a short distance along the sides. The re- flected portion equals only one-fourth of the length of the base of at- tachment. It is stout, and bears a short, stout median cusp, having a short, blunt cutting point. There are no side cusps or cutting points. The laterals are like the centrals, but asymmetrical; their reflected portion is also longer. The outer laterals {h) have an outer side cusp. The marginals (c) are a simple modification of the laterals, being quad- rate, longer than wide, with one inner, broad, long, oblique, bluntly pointed cutting point, bearing an inner, side, short, acute cutting point. These cutting i)oints on the extreme marginals [d) are simply short and bluntly rounded. Some membranes examined by me seemed to have an extension to the base of attachment beyond the upper margin of the reflected j^ortion, to which it was parallel. This membrane is peculiar in the long, narrow base of attachment and short, reflected portion of the central and first lateral teeth. Tebennophorus Caroliiiiensis, Bosc. Color of upper surface whitish or yellowish-white, variegated with clouds and spots of brownish and blackish, so arranged as to form three ill-defined longitudinal bands, one on the center of the back and one on each flank, extending from the head to the posterior extremity, anas- tomosing more or less with each other, and having smaller spots of the same color between them ; i
