Albany Island, North Australia, 3-8 fms, {Ooppinger) ; Dupuch'sIsland, Torres Straits {Reeve).A single specimen from Albany Island belongs to the pale variety(fig. 21 «, Con. Icon.) with a reddish-pink peristome, and has a remarkablefrond on the labrum, the second from the top, measuring55 millimetres in length. The tooth on the labrum exhibits aremarkable development in this species.19. Fusus hanleyi.Trophon hanleyi, Angas, Proc. Zool. Soc. 1807, p. 110, pL xiii. fig. 1.Fusus hanleyi (-£". Smith .'), Sowerby, Thes. Conch, p. 83, fig. 145.Hah. Port Jackson {Angas and Coppinger) ; Port Curtis {Ooppinger).Mr. Sowerby erroneously attributes this species to me ; the coarsenessof his figure renders it of but little use, that in the ' Proceedings'being far preferable.20. Fusus heptagonalis.Reeve, Conch. Icon. fig. 2Qa,h; Soioerby, Thes, Conch, fig. 132.Hah. ? Port Molle, Queensland {Ooppinger).The colouring of Sowerby's figure is totally incorrect, and it is notnearly so accurate with regard to sculpture as that in the CouchologiaIconica.' This species is not always heptagonal, the number'of ribs in three cases out of four being eight instead of seven. Whenin fine condition the spiral ridges of this species are finely imbricatelyscaled by the parallel wavy lines of growth. The only specimenobtained by Dr. Coppinger is in a bad state of preservation,and of a considerably more dwarfed or stunted growth than the typeand two other specimens in the Eritish Museum. It is, however,adult, exhibiting the thickened lip and eight lirao within of an adultshell. The canal, too, is short, and the last whorl has an inconspicuouspale zone around the middle, also observable in one of the otherspecimens above referred to.21. Fusus cereus. (Plate V. fig. D.)Shell short, ovately fusiform, pale yellowish, ribbed, and transverselyscabrously lirate. Whorls about 8, the remaining sixthickened beneath the suture by a stout ridge, then obliquely sloping,angled at the middle and contracted at the base, strengthenedwith eight stout costa3, which are obliquely contiuuous up the spire,and crossed by four spiral squamose liraD, two of them aroiind thelower half of the whorls being twice as thick as the other two above,and particularly prominent upon the ribs. The last volution, in
