358 ENTOZOA. 
Prennevia, Oken, 
The head is inflated, the nape furnished with two small horns, and 
the neck corneous; the body is long, transversely rugose, and pro- 
vided posteriorly with little filaments arranged like the laminz of a 
feather. The two very long filaments arise from the commencement 
of this plumous portion. 
P. filosa; Pennatula filosa, Gmel.; Boccone, Mus., 2863 Ellis, 
Phil. Trans., LXIII, xx, 15. From seven to eight inches in 
length; it penetrates into the flesh of the Xiphias, Thynnus, and 
_ Orthagoriscus, tormenting them horribly. It is found in the 
Mediterranean(1). 
In a third group, 
Spuyrion, Cuv. 
The head is widened on each side like a hammer, and the mouth 
is furnished with hooks; the neck is slender, and followed by a de- 
pressed and cordiform body, which, besides the two long cords, is 
provided with a thick bundle of hairs(2). 
In a fourth, 
ANCHORELLA, Cuyv. 
_ The animal is only fixed to the gills by a single production,-which 
originates underneath the body, and is directed posteriorly(3). 
In a fifth, 
BRACHIELLA, Cuv. 
We observe two prominences somewhat similar to two arms, 
which unite in one corneous body, by which the animal fastens itself 
to the gills(4).
