Teeth of Etmopterus baxteri (synonym of E. granulosus): Teeth 14-1-14/25-27, dissimilar in the two jaws. The upper teeth erect, each with a long, sharply-pointed, awl-shaped, smooth-edged major cusp flanked on each side by up to four small lesser cusps, and borne on a longitudinally-striated bifid base. Most of the upper teeth have three lesser cusps on each side of the major cusp, with the middle cusp of these three considerably larger than the others though not more than one-third the length of the major cusp. A few teeth near the centre of the jaw have four lesser cusps on each side, with the largest lesser cusp separated from the major cusp by two small lesser cusps, while in the teeth towards the angle of the jaw there is a reduction in the number of lesser cusps to one or two on each side. Three series of upper teeth functional at the centre of the jaw, two towards the angles. The lower teeth blade-like, each with a smooth, little-sculptured, rectangular base almost twice as high as broad, and bearing a single, smooth-edged, triangular cusp. Each cusp is sharply notched laterally, strongly oblique, and overlaps the adjacent cusp so that an almost continuous cutting edge is formed. There is no median tooth, and the base of the first tooth on the left side overlaps that of the first tooth on the right. A single series of lower teeth functional [2751];
