410 ENTOZOA. 
L. ocularis, Cuy., fastens itself to the eyes of Herrings and 
other fishes ; its horns are simple and short, two larger and two 
smaller; the body is slender, and its cords long and not 
doubled*. 
L. multicornis, Cuv., is another with very numerous, small, 
and unequal horns, found on the gills of a Serranus in the East 
Indies. i 
In another group, 
PENNELLA, 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 lamine of a 
feather. The two very long filaments arise from the commencement 
of this plumous portion. 
P. filosa; Pennatula filosa,Gmel,; Boecone, Mus., 286; 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 f. 
In a third group, 
Spuyrion, Cwv., 
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 pro- 
vided with a thick bundle of hairs ¢, 
In a fourth, 
ANCHORELLA, Cuv., 
The animal is only fixed to the gills by a single production, which 
originates underneath the body, and is directed posteriorly §. 
In a fifth, 
BRACHIELLA, Cuw., 
We observe two prominences somewhat similar to two arms, which 
unite in one corneous body, by which the animal fastens itself to the 
gills ||. 
In a sixth, 
Lernea itself. This fact, added to the observations of Messrs. Audouin and Milne 
Edwards, relative to the Nicothoe dstaci, has inclined those naturalists to the opinion 
that most of these Lernzz may be Crustacea that have become monstrous subsequent 
to being fixed, and that the males remain free; which, according to them, explains the 
circumstance of our being able to find females only.—Ann. des. Sc. Nat., IX, 345, pl. 
xlix. Before this idea can be received as definitive, we must be able to find these 
males.
