MOLLUSCA. 
tion of this species is sometimes used in France for pulmonary 
disorders*. 
Lima, Feruss. 
The respiratory opening towards the posterior jiart of their shell, 
and frequently much larger. Such is 
L. atitiqiionim, Feruss., pi. iv and viii. A, f. 1 ; L. maximus, L. ; 
L. sijlvaticm, Drap., Moll., IX, x. Frequently spotted or streaked 
witli grey ; found in caves and dark forests. 
L. agresfis, L. ; Feruss., pi. v, f. 5 — 10. Small, without spots ; 
and one of the most abundant and destructive animals. f 
Vaginulus, Ferms. 
Have a dense mantle Avithout shell, stretching over the Avhole 
length of the lody ; four tentacula, the loiver ones slightly forked : 
the anus at the extreme posterior extremity, between the point of the 
mantle and that of the foot, the same orifice leading to the pulmonary 
cavity situated along the right flank ; orifice of the male organ of 
generation under the right inferior tentaculum, and that of the 
female under the middle of the right side. These organs, as Avell as 
those of digestion, are very similar to the same parts in the Slug. 
Tliese Mollusca are found in both Indies, and closely resem- 
ble tlie common Limaces|. 
Testacella, Lam. 
Have the respiratory crific and the anus at the posterior extremity; 
the mantle very small" and placed on the same extremity ; it con- 
tains a small oval shell, Avith an exremely Avide aperture and a A^ery 
small spine, Avhieli is not one tenth of the length of the body ; otlier- 
Avise tliese animals resemble the Limaces. 
Test, haliotoidea, Drap. ; Ciw., Ann. du Mus., V, xxau, 6, 11. 
A common species is found in the southern departments of France; 
* A.cld : the L. albtis, MiilL, Fo'russ., pi. i, f. .3 ; — L. hortensis, Id., pi. ii, f. 4 — G. 
'f- Add : L. ulpinus, Feruss., pi. v. a; — L, gugutes, Drap., pi. ix, f. 1 and 2, &c. 
N.B. The Plectophoiia, Feruss., would be Limaces, having a sort of small conical 
shell on the end of their tail, and far from the shield ; they are only known, however, 
liy drawings of very equivocal authority, Favanne, Zoomorphose, pi. Ixxvi, copied 
Fei’uss., pi. vi, f'. G, 6, 7. 
M. de Blainville (Malac., p. 464) now doubts the reality of his genus Limacella, 
and rejects his genus Ykronicella, Diet, des Sc. Nat. The Phylomichus and 
Eumei.es. Raf., are too imperfectly indicated to be admitted into a work like this. 
I Vaginulus Tuunaisii, Feruss., pi. viii. A, f. 7 ; and viii, B, 2 3 ; — V. alfiis, Id., 
pi. viii. A, f. 8, and viii, B, f. 6 ; — V. Langsdorjii, Id., pi. viii, B, f. 3 and 4 ; — F. 
IfPfigatus, Id., pi. viii, B, f. 5, 7 ; — Onchidium occidenlale, Guilding, Lin. Trans. 
XTV, ix. 
The genus Meghimatium of Van Hassel., Bullet. Univers., 1824, Zool. tome 
III, p. 82, should apparently be added to it. 
N. B. The genus Yaginula differs from Onchidium, Avitli which M. de Blain- 
ville has united it, Malac., p. 465, detaching from it, at the sume time, the true 
Onchidiums to form his genus Peronia. His anatomy of the Yaginula in the Moll. 
Terr, et Fluv. of M. de Ferussac, pi. viii, C, is very good.
