OBSERVED AT MOGABOR. 203 



Hah. In Mad., lus. Can. (Lanzarote, Fuerteventura, Teneriffe, 

 Gomera), Hispania (Malaga), Lusitania (prope Lisboam), Italia 

 (prope Bolsenam), &c. 



/3. decussata. Striis incremeuti subdistinctioribus lineisque spiralibus 

 subtilissimis paucis obsolete decussata. 



Found intermixed with a in the Canaries, Spain, Italy, &c., but 

 not in JSIadeira. 



In size, colour, habit, &c., agreeing perfectly with a, but ap- 

 proaching B. Faivce in the decussated sculpture, which is, how- 

 ever, mostly irregular and much fainter, or sometimes almost 

 evanescent. 



14. Achatina folUcuhts (Gron.), Pf (ed. 1) ii. 283. 



a. ahhreviata ; loug. 9, diam. ^\ ; apert. long. 4 millim. 



Near Mogador, at the Emperor's Garden up the river. Agrees 

 with Portuguese better than Madeiran specimens, in the more 

 prominent columella. See Catal. Moll. Mad. in Proceed. Zool. 

 Soc. 1854, p. 200. 



/5. prodiicta ; long. 10, diam. 3|- ; apert. long. 4 millim. 



From Eabat, a single specimen, Mrs. Elton. Differs from a only 

 in the spire being longer in proportion to the aperture, and in the 

 less prominent or developed columella. In this latter point it 

 agrees with Madeiran better than with Portuguese examples. 



15. Acliatina ruricola, Lowe. 



T. majuscula sat firma subpellucida turrita subcyliudracea elongata gra- 

 ciliuseula, spira producta obtusiuscula ; anfr. 6 planis aequalibus 

 sutura subindistincta parum impressa marginata obliqua ; apert. 

 ovata sursum acuta nee acuminata ^ fere (vix ultra) longitudinis 

 sequante ; columella arcuata subdilatata basi vix prominula obscure- 

 que oblique truncata, peristomate simplici. 



Long. 8, diam. 2\; apert. long. 2f millim. 



Hab. Prope Mogador in rure, n-r. 



Partaking chiefly of the characters of A. maderensis and A. pro- 

 ducta, Lowe, this elegant little species, of which I found a single 

 example at the picturesque spot already so often mentioned, 

 called the Emperor's Garden, about four miles from Mogador up 

 the river, is perfectly distinct from each; and it will not even 

 enter into either of the groups to which they respectively belong, 

 appertaining properly to that of A. folliculus (Gron.). In shape 

 both of the shell and of its aperture it most resembles A. made- 

 rensis, Lowe ; but it wants the peculiar bright polish; it is twice as 

 large ; the spire is miicli less blunt, with flatter volutions and a
