ELEDONE. A479 
4. On the ventral surface of the mantle sac the 
brownish chromatophores are larger than in other parts 
of the mantle, and situated further apart. The prevailing 
colour here is white, with a light, metallic green cast. 
5. The dorsal surface of the visceral dome, like that 
of the web and head, shows patches of cream in between 
large flecks of a reddish-buft colour. From the eyes two 
oblique lines of cream colour slant inwards and meet, 
forming a light-coloured V on the dorsal surface of the 
head. ‘The iris of the eye is deep orange in colour. The 
chromatophores are continued over the free edge of the 
mantle, for about half an inch inside the pallial cavity. 
The marbling of the skin is most distinct when the 
animal is recovering from excitement. When quiet the 
cream and buff flecks fade into one another rather 
indistinctly, while the intense blush caused by excitement 
spreads all over the skin and temporarily eliminates the 
marbling, but when recovering again, the cream flecks 
show up well against the terra-cotta patches. When the 
animal is excited the skin becomes of a very dark reddish 
terra-cotta tinge. After death the eyes become dull, and 
the skin loses its velvety gloss and beautiful colouration 
utterly, and becomes overcast with a dull grey tinge. 
When Eledone is frightened in any way, the skin changes 
colour, and an intense pallor spreads over it, causing it to 
become quite ghostly in appearance. At this time the 
eye stands out very prominently, because the iris remains 
dark orange, as does the eyelid surrounding it, and thus an 
orange circular patch marks out the eye, on a whitened 
body. However, under normal conditions this patch does 
not stand outin any way. At the same time that the pallor 
is seen the animal tries to escape by rapidly swimming 
backwards, and attempts to eject ink. Almost 
immediately the pallor is replaced by an _ intense
