with white. Dorsal tentacles long, produced, clavated, trun- 

 cated superiorly, laminated : of a pale purplish colour. Mouth 

 with a small triangular shaped veil. Branchial plumes 5 ; 

 large, broad and long ; closely tripinnated ; of a rusty red 

 colour, grizzled with white. Foot short, oblong, oval; of a 

 purplish pink colour ; sides of under surface veined and of a

The mantle of this inelegant Doris, is not unlike some car-

 edge of the mantle of the young is mottled yellow. The 

 whole animal is nearly 5 inches long, and 3 J broad in the 

 centre. Ova white, deposited in narrow tape-like form in 4 

 or 5 broad coils. The white ova alone sufficiently distin- 

 guish this ugly Sea nymph from her rival D. exanthemata.

 Oral tentacles long, linear, pointed ; of a bright brown colour. 

 Branchial plumes 6, tripinnated ; of a golden brown colour. 

 Foot golden brown ; narrow, longer than mantle. 



This warty Doris is easily distinguished from others of a 

 brown colour by its rufous warty mantle, and the dirty white

 Very common in low water in the months of September 

 and October.
