Excerpt from L. M.B.C. Memoirs on Typical British Marine Plants Animals, Vol. 7: Lineus Two very distinct colour varieties are to be met with, viz., reddish brown and olive green - the latter being the more common. Specimens intermediate between these two are also frequent. The colour is more pronounced in front, and is darker on the dorsal surface than on the ventral. The snout and mouth are bordered by pale margins. On the head a reddish patch marks the position of the brain, and a bright red colour-ation is also found in the head slits which is said to be due to the presence of haemoglobin. On the snout in front of the brain occur the deeply pigmented eyes usually varying from 8 to 0 in number on each side, though more may be present on one side than on the other.
