Anthea Tuediae is amongst the largest of our species. The body, 
when relaxed, generally measures three inches in length, and about 
the same in diameter ; it is of a uniform reddish or brownish-orange 
colour, and either smooth or contracted at pleasure into circular folds. 
The base is smooth and orange-coloured, with a thin areolar skin. 
The mouth is ever varying in size and form, and there are often pro- 
truded from it vesicular-like lobes of a reddish colour scored with 
fainter lines. When fully expanded, the oral disk is not less than 
four inches across ; there is a smooth space between the mouth and 
tentacula, which are very numerous, and placed in several rows 
around the circumference ; those of the inner row are larger than the 
others, measuring frequently two inches in length, and they become 
gradually shorter in the exterior series. They are of a chesnut or 
reddish flesh colour, often darker coloured towards the bases, but 
never variegated with rings of different hues, thick and clumsy, ta- 
pered to an obtuse point, marked longitudinally with distinct lines or 
impressed striae, tubular, perforated at the ends, and constricted at 
their insertions. The creature has no power of withdrawing them 
within the oral aperture, nor does it seem capable even of shortening 
them in any considerable degree, but it twists them in a wreathed or 
spiral form, or gives the whole circle a greater or less degree of ex- 
pansion.
