II. Descriptions of a few Invertebrated Animals obtained at the Isle of France.

THE following paper is devoted to the description of a few Invertebrate Animals which 
were selected from the specimens I brought home with me from the Isle of France, and 
of which descriptions, as far I can ascertain, have not yet been offered to the public. 
Genus Acrinia, Linn. 
ACTINIA SANGUINEO-PUNCTATA. 
Tab. V. Figg. 1, 2. 
Act. flavescenti-rufescens, guttulis punctisque sanguineis confertis per series lonyitudinales 
numerosas dispositis ornata ; ore guttis ceruleis quinque circundato ; tentaculis viri- 
descentibus, hyalinis. 
Reddish brown, or yellow, with longitudinal rows of brilliant red dots, the interspaces 
being charged with minute concolorous points. The tentacula are subulate, hyaline, 
greenish brown with pinkish tips: from their base white streaks pass towards the 
centre, becoming lost in the depression which surrounds the truncate cone bearing the 
mouth. The mouth is very small, and has five blue patches coalescing and encircling 
it. The base is lobed, formed of a very fine membrane, which is thrown into folds by 
a set of internal, apparently muscular, partitions, which radiate irregularly from the 
centre. 
This species appears hitherto undescribed. It is exceedingly pretty in the water, but 
never arrives at a large size, an inch being the utmost limit I have ever found it to 
attain. It is found on the rocks, beneath low water mark, nearly all round the Isle of 
France ; but does not appear to thrive well where the water is much agitated by the 
wind or south-east swell. 
Genus Xenia, Lam. 
Xenia DesJARDINIANA. 
Tab. V. Figg. 3—8. 
Xen. pallidé livido-cerulea ; polypis 8-, rarivs 9-radiatis. 
VOL. 1. E
