These openings, however, are at the ends of tubes the inner extremities of which are in front of the [supratemporal] canal. The canal is nearly straight, bending slightly forward in the middle and a little backward near each end. . At the end of the jugular, near the middle of the first branchial aperture, there are two branches not found in any other of the sharks examined: a spiracular [HLC in Figure 29, plate VII], turning upward and forward toward the spir- acle; and a gular [HLB in Figure 29, plate VII], turning down and forward near the median line, and finally uniting with the oral [HLA in Figure 29, plate VII] a short distance from the inner end. . Apparently the pre- nasal is reversed in direction, meeting the nasal in front and running backward to join the sub- rostral. . Like the corporals, the oral, gular. Text-figure 128.
