32 MOLLUSC A. 



tion of this species is sometimes used in France for pulmonary 

 disorders*. 



Lima, Feruss. 



The respiratory opening towards the posterior part of their shell, 

 and frequently much larger. Such is 



L. antiquorum, Feruss., pi. iv and viii, A, f. 1 ; L. maximus, L. ; 

 L. sylvaticus, Drap., Moll., IX, x. Frequently spotted or streaked 

 with grey ; found in caves and dark forests. 



L. agreslis,Ij. ; Feruss., pi. v, f. 5 — 10. Small, without spots ; 

 and one of the most abundant and destructive animals. f 



Vaginulus, Feruss. 



Have a dense mantle without shell, stretching over the whole 

 ](>ngth of the liody ; four tentacula, the lower 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 riglit inferior tentaculum, and that of the 

 female imder the middle of the right side. These organs, as well as 

 those of digestion, are very similar to the same parts in the Slug. 



These MoUusca are found in both Indies, and closely resem- 

 ble the common LimacesJ. 



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, with an exremely wide aperture and a very 

 small spine, wliicli is not one tenth of the length of the body ; other- 

 wise these animals resemble the Liniaces. 



Test, haliotoidea, Drap. ; Cuv., Ann. du Mus., V, xxvi, 6, 11. 

 A common species is found in the southern departments of France; 



* Add : the L. aWtis, MiiU., Feruss., pi. i, f. 3 ; — L. hortensis, Id., pi. ii, f. 4 — G. 



f Add : L. alpinus, Feruss., pi. v. a; — L. (jugates, Drap., pi. ix, f. 1 and 2, &c. 

 N.B. The Plectophora, 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, 

 by drawings of very equivocal authority, Favanne, Zoomorphose, pi. Ixxvi, copied 

 Feruss., pi. vi, f. 5, 6, 7. 



M. de Blainville (Malac, p. 464) now doubts the reality of his genus Limacet.la, 

 and rejects bis genus Veronicella, Diet, des Sc. Nat. The Phylomichus and 

 EuMELES, Raf., are too imperfectly indicated to be admitted into a work like this. 



X Vayinidus Taunaisii, Feruss., pi. viii, A, f. 7 ; and viii, B, 2 .3 ; — V. alius, Id., 

 pi. viii, A, f. 8, and viii, B, f. 6 ; — V. Langsdorfii, Id., pi. viii, B, f. .i and 4 ; — ]'.

 XIV, L\. ; 



The genus Meghimatium of Van Hassel., Bullet. Univers., 1824, Zool. tome 

 III, p. 82, should apparently be added to it. 



N.B. Tlie genus Vaginula differs from Oxchidium, with 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 Peroxia. His anatomy of the Vaginula in the Moll. 

 Terr, et Fluv, of M. de Ferussac, pi. viii, C, is very good.
