    the Macleay-Museum, which had been preserved in spirit for a moderate period (2-3 monthsf), to which circumstance is also to be attributed the stiffness of fig. 8. The marking characteristic of the species, however, I have represented as seen in perfectly fresh specimens, since it becomes indistinct only a few hours after death. Fig. 3 (pi. 22).—View of the dorsal surface. The dorsal fins are somewhat bent to one side. The eyes are not to be seen, when the head is viewed from above, on account of the overhanging eyebrows (vide. fig. 9). Fig. 4 (pi. 22).—Ventral aspect. (The black line, drawn with the pen, on the lower part of the body, between the abdomen and the anus, and the anal fin is an unnatural representation of the slightly depressed mesial line.) Fig. 8 (pi. 23).—Lateral view of the same. Fig. 9 (pi. 23.)—Head of a young H. PMllipi, about 761 mm. (221 in.) in length, drawn from a fresh specimen (with the aid of the camera lucida and compasses). Fig. 10 (pi. 23).—Anterior part of the head of the same young fresh specimen viewed from the ventral aspect. [After looking at fig. 10, compare it with fig. 29 (pi. 25) in order to obtain a correct idea of the nasal grooves with both their orifices.] Figs. 11, 12, 13 (pi. 23) represent three profile-views of the mouth of the same (761 mm. or 22T in. long) B. PMllipi. Fig. 11 (pi. 23).—Mouth closed. Fig. 12 (pi. 23).—Mouth half open. Fig. 13 (pi. 23).—Mouth open to its utmost extent. PLATE 24. Hkterodontus Phillipi, PI. Figs. 14 and 15.—Teeth of the upper and lower jaws of the young H. PMllipi, figured on plates 22 and 23 (figs. 1, 2, 8.) The sketch, of about five times the natural size, was made from a photograph (by which the increase in size was effected.) Through the carelessness of the artist who copied the photo- 127] I
