A female specimen of Heterodontus galeatus Giinther captured off Sandon Bluff, New South Wales, Australia. The inset figure shows the mouth opening, the nares, oro-nasal grooves, labial folds and some of the front teeth. After Whitley, 1940, Fig. 56, p. 73. The most outstanding peculiarity of this species is the unusual height of the supra' orbital ridges. These ridges approach each other anteriorly, and diverge posteriorly; they end abruptly a short distance behind the eye. Garman (1913) says that they end ab' ruptly in young specimens, less so in old. As shown in a frontal view by Maclay and Macleay (1879) the ridges lean outward (laterad) at an angle of about 45 degrees from the median plane. Waite (1898 and 1899) and Whitley (1940) refer to this shark as the "crested species". The name Crested Shark seems appropriate, though it might with some justice be applied to any species of Heterodontus. The name "Crested Port Jackson Shark", used by Whitley, seems inadmissable. Garman (1913) states that the form of H. galeatus is similar to that of H. francisci, but the head is short and angular. The anterior gill-opening is more than twice as "wide" (presumably meaning high or long) as the hindmost. The origin of the first dorsal fin is above the hinder part of the pectoral base; the hind margin of the first dorsal is concave. The base of the anal fin is about two-thirds of its length distant from the lower lobe of the caudal. The color pattern is not well shown in Maclay and Macleay's lateral view (1879), but is quite distinct in their dorsal view of the same specimen. Six broad transverse dark stripes are said to be visible, but in the drawing the most posterior stripe is very faint. Garman (1913) states that the general color is brown, with a transverse stripe of darker across the orbits, widen
