Altogether 28 specimens, 5 ft. 5 in. to 6 ft. 7 in. long were caught. Some of the females were gravid, the embryos being in separate compartments, others had evidently bred. From five to ten embryos constitute a brood, each between 15i and Hi in. (388 to 438 mm.) long. I saw one female caught off Bunbury, the southernmost limit. A female specimen, 1,890 mm. long and weighing 100 lb., from Dirk Hartog Islan

From five to ten embryos constitute a brood, each between 15i and Hi in. (388 to 438 mm.) long. I saw one female caught off Bunbury, the southernmost limit. A female specimen, 1,890 mm. long and weighing 100 lb., from Dirk Hartog Island, is here figured. Its ovaries extended most of the length of the coelome, no ova were visible and the uteri were flaccid, so it had perhaps bred some time previously. General colour pale grey above and parchment white below; iris pale bronze. The presence of an interdorsal ridge which becomes obsolete before reaching either dorsal fin (as in G. eblis Whitley, to which this species is. 3. Sand Shark, Galeolamna dor salts, Whitley. Female from Dirk Hartog Island. Dorsal, lateral and ventral views; teeth and dermal denticles. most closely allied) is noteworthy, but dorsalis is always separable from eblis by its higher dorsal fin. In dorsalis the distance from the origin of the first dorsal fin to its tip goes about 5 to 5£ times in total length, but in eblis it goes 8 to 9 times in the same. The head of dorsalis is generally about 4^ to 5£ in total length, rarely 4 or less, as in eblis. In dorsalis the pectoral fins are very long, the second dorsal fin is larger and pectoral angle further back than in eblis. It seems likely that eblis breeds at a much larger size and has much larger embryos, but I have incomplete data on.
