330 MOLLUSCA. 
ANIMAL with the foot of a clear ochreous red, darkest at the margin ; 
head rather paler, mouth not surrounded by a veil or hood, but sunk 
in the centre of the cephalic mass, the labial dilatations scarcely appa- 
rent; branchie of a darker colour, continued to the anal tube; under 
surface of the margin clear orange. In some individuals the foot 
is flesh-coloured, and the margin roseate: this variety is barred lake 
and orange above. In others, the foot is ash-coloured, and the margin 
barred dark purple and cinereous. 
The sHett exhibits a great variety of colours, from a uniform dark 
chestnut and purple banded, to a pale green, with roseate or pale 
green bands. Scarcely any two are alike; most varieties turn darker 
on drying. They were peculiar for being always remarkably clean, 
while other species in the same pools would be loaded with zoophytes 
and Fuci. 
It is allied to C. Bowent, King, but it never becomes black or is 
destitute of marginal bars. The margin has a slight velvety feel when 
fresh, becoming horny when dried. [s. P. c.] 
Found in pools at Orange Harbour.

There can be little doubt that this is Chzton Merckiz, Middendorff, 
in Mem. de l’Acad. des Sciences de St. Petersbourg, Sciences Natu- 
relles, vi. 179, tab. xi., figs. 5, 6. The margin, which was imperfect 
in our specimens, is described as “limbus pilosissimus, mediocris.”
