32 MOLLUSCA. 



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

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

 with grey ; found in caves and dark forests. 



L. agrestis, L. ; 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 

 length of the body ; 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 right inferior tentaculum, and that of the 

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

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



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

 ble the common LimacesJ. 



TESTACELLA, Lam. 



Have the respiratory orific 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, which is not one tenth of the length of the body ; other- 

 wise these animals resemble the Limaces. 



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. albus, Miill., Feruss., pi. i, f. 3 ; L. hortensis, Id., pi. ii, f. 4 G. 



f* Add : L. alpinus, Feruss., pi. v. a; L. gugates, 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 LIMACELLA, 

 and rejects his genus VERONJCELLA, Diet, des Sc. Nat. The PHYLOMICHUS and 

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



Vaginulus Taimaisii, Feruss., pi. viii, A, f. 7 ; and viii, B, 2 3 ; V. altns, Id., 

 pi. viii, A, f. 8, and viii, B, f. 6 ; V. Langsdorfii, Id., pi. viii, B, f. 3 and 4 ; '. 

 Itirit/n/ns, Id., pi. viii, B, f. 5, 7 ; Onchidinm occidentale, Guilding, Lin. Trans. 



xiv, ix. : 



The genus MEGHIMATIUM of Van Hassel., Bullet. Univere., 1824, Zool. tome 

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



N.B. The genus VAGINULA differs from ONCHIDIUM, with which M. de Blain- 

 ville has united it, Malac., p. 465, detaching from it, at the sume time, the true 

 Onrhidiums to form his genus PI;UOXIA. His anatomy of the Vaginula in the Moll. 

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