A single specimen from Albany Island belongs to the pale variety 

 (fig. 21a, Con. Icon.) with a reddish-pihk peristome, and has a re- 

 markable frond on the labium, the second from the top, measuring 

 55 millimetres in length. The tooth on the labrum exhibits a 

 remarkable development in this species.

Air. Sowerby erroneously attributes this species to me : the coarse- 

 ness of his figure renders it of but little use, that in the ' Proceedings ' 

 being far preferable.

The colouring of Sowerby's figure is totally incorrect, and it is not 

 nearly so accurate with regard to sculpture as that in the ' Concho- 

 logia Iconiea." This species is not always heptagonal, the number 

 of ribs in three cases out of four being eight instead of seven. When 

 in fine condition the spiral ridges of this species are finely irnbri- 

 '.V scaled by the parallel wavy lines of growth. The only spe- 

 cimen obtained by Dr. Coppinger is in a bad state of preservation, 

 and of a considerably more dwarfed or stunted growth than the type 

 and two other specimens in the Pritish Museum. It is, however, 

 adult, exhibiting the thickened lip and eight line within of an adult 

 shell. The canal, too, is short, and the last whorl has an inconspicuous 

 pale zone around the middle, also observable in one of the other 

 specimens above referred to. 



21. Fusus cereus. (Plate V. fig. D.) 



Shell short, ovately fusiform, pale yellowish, ribbed, and trans- 

 versely scabrously lirate. "Whorls about 8, the remaining six 

 thickened beneath the suture by a stout ridge, then obliquely slo- 

 ping, angled at the middle and contracted at the base, strengthened 

 with eight stout costie, which are obliquely continuous up the spire, 

 and by four spiral squamose lirce, two of them around the 



lower half of the whurls being twice as thick as the other two above, 

 and particularly prominent upon the ribs. The last volution, in
