■ Doris cocdnea,tForbes, in Report Brit. Assoc, for 1843, p. 133.
Hab. Under stones and rocks between tide-marks; not uncommon on the Cornish Coast.
Body rather above half an inch’long* a little depressed, ellipttöroblong, with the sides
nearly pafhllel. Cloak not extending much beyond the foot, of a bright scarlet colour,
generally' sprinkled with small black spots, and thickly covered with very mimite spiculose
tubercles of nearly equal size; under side of the same colour as the upper, without markings.
Dorsal tentacles stout, short, and clavate, yellowish, blotched with brown; transparent
towards the base; they have about ten broad laminm, deeply cleft and widely separated in
front, and spreading much on each side, above which the tentacle is terminated by a slender
projecting stile with an obtuse apex. •' The apertures are without sheaths,>«but surrounded by
pale, opaque; yellow tubercles, larger than those on the other parts of the cloak, with a few
intermediate dark brown or black markings: the tubercles are also larger, and of the same
yellow colour between the tentacles, uniting them by an indistinct band. BrancJua very
smalfi'formihg a small, almost complete circle,,consisting of ten slender, upright, sharp-pointed,
and simply pinnate plumes of a red-colour, paler than th # cloak, and ipclining to pink; the
two posterior plumes are smaller than the rest, and appear to arise ffdin’ the, base of those
next to them!' The wholé' are retractile w ithi^smallcavity. Oral tentacles%og, linear, and
slender, tapering towards the points. Head tubular,'rounded in frpnt, with the lips fleshy.

appearing through. I t is roundedrand cleft transversely in front, with the upper lamina^
notched in the centre; ibe posterior extremity is pointed, and extends a little beyond the
cloak when the animal is crawling.
This handsome species was first sent us from Polperro on the Cornish coast by.Mr. R. Q.
Cduch, and afterwards by Mr. Cocks from Falmouth. On a recent visit to the latter place,
we found it not u n c om m o n there.in the month of June, and, with -the exception of
D. tuberculata, it was t6en the only species observed on the rocky parts of the coast.
We have ascertained, by a comparison with Professor Edward Forbes’s drawings, kindly
lent us for the purpose, that this is the species^ mentioned in his ‘ Report on the lEgean
Mollusca,’ under the name of Doris coedinea. We hesitate, however, to unite it with the
Doris found by the same distinguished naturalist in the Isle of Man, and described , in the
‘ Annals of Natural Hikory’ (vol. v), as D. argo. The latter will much more likely prove to
