228 MOLLUSCA. 
jfimbriatum, Martyn’s Univ. Conch., pl. 1, f. 6. Murex Magellanicus, 
GME vIN and Lamarck, Anim. sans Vert., ix. 589. 
Animat of a uniform ochreous yellow, somewhat paler on the disk 
of the foot, which is small, oval, truncated anteriorly, with a deep 
fissure across. Head distinct, somewhat elongated; mouth inferior at 
the extremity, the upper edge of the head prolonged over it like a hp, 
giving it much the appearance of an inverted glove-finger. ‘Tenta- 
cles short-conical; eyes on a lateral protuberance about halfway up.

Some of the shells have a remarkably bulbous form, and have no 
conspicuous, longitudinal lamine, but merely distinct, revolving 
grooves; and there is every variety between this pattern and the 
remarkably clathrate surface of the typical form.

Fusus tacrntatus (Martyn), Univ. Conch., pl. 42. Murex lamel- 
losus, LAMaRcK, Anim. sans Vert., ix. 591. 
AnrMat very sluggish ; throughout several days’ confinement, during 
which the water was changed twice daily, it never protruded more 
than is represented in the drawing. ‘The tentacles are conical, com- 
pressed, and rather short, with the eyes lateral at the superior third. 
Foot thick, short and broad, regularly rounded behind, and truncate 
in front, with a submarginal groove; pale yellow beneath. Siphons 
short, and like the mantle, of a pale yellow; the margin of the mantle 
appears destitute of any fringe. 
Obtained at Orange Harbour, but appears not to be common.
