and the coast. I cannot see that they differ appreciably from 

 the Madeiran ones ; and Mousson also came to the conclusion 

 that they are specifically identical with the ordinary type, of 

 more northern latitudes. ' M. Wollaston a recueilli,' says he, 

 ' un bon nombre d'individus de cette petite coquille a l'etat 

 vivant, tandis qu'ordinairement on ne la trouve que morte. 

 J'ai longtemps hesite a lui appliquer le nom de l'espece euro- 

 peenne, mais un examen scrupuleux ne me permet pas d'etablir 

 des differences palpables et constantes. Notamment la co- 

 lumelle un peu excavee, se prolongeant jusqu'a la base de 

 l'ouverture et se terminant la par une troncature franche, est la 

 meme ; c'est dans cette partie que se manifestent le plus aise- 

 ment les differences specifiques dans ce petit genre, si difficile a 

 eclaircir.' 



G-enus 14. LOVE A, Watson. 



I have already mentioned, at p. 247 of the present volume, 

 that the Canarian ' Achatinas ' of this particular type are too 

 nearly related to the Madeiran ones not to be admitted (by 

 presumption) into the same genus with them ; though I would 

 wish expressly to state that their animals, in which alone the 

 generic peculiarities reside, have yet to be examined. The 

 characteristics of Lovea, as recently established (Proc. Zool. 

 Soc. Lond. 677; 1875) by Mr. Watson, consist in the tail of 

 the animal being not only obliquely lopped-off at the tip and 

 provided with a mucous gland at the angle of the truncation, 

 but likewise in the mantle extending ' beyond the edge of the 

 aperture, all round,' and in being prolonged backwards ' like a 

 tongue, behind the posterior corner.' The very highly polished 

 surfaces of the Loveai seem to be connected, as Mr. Watson pro- 

 perly observes, with the perpetual movement upon it of the mantle, 

 and especially of its posterior prolongation ; though at the same 

 time I would remark that this particular feature is equally 

 conspicuous in numerous other species, such as the A. acicula 

 and lubrica, in which the latter has not been observed to hold 

 good — at any rate to a similar extent. 



As regards the species enumerated below, the L. Reissi is so 

 nearly related to the folliculus, Grron., as to be barely separable 

 from it ; and since the latter has been ascertained, both by 

 Mr. Watson and myself, to possess the exact distinctions of 

 Lovea, we may feel pretty confident that the former will be 

 found to possess them equally. And inasmuch as the Reissi 

 belongs unmistakeably to the same type, or section, as the 

 various species which succeed it, there can be little doubt that 

 they are all of them Loveas, as defined, and limited, by Mr. 

 Watson.
