414 On the Land I Shells of JJovrbon. [No. \, 



32. Sttccixea mascarexsis, n. pp. 



This shell is also common at Mauritius, where it lives in the 

 cultivated plains on walls &c, Deshayes records it, Moll, do 

 la Eeun. p. 90, as S. striata f Krauss, which it certainly closely 

 resembles, but can be distinguished by its less ventricose and more 

 attenuated form. It also resembles Quoy's Succinea australis from 

 Tasmania. 



Shell resembling S. striata, Krauss, but smaller, with the last 

 whorl and the aperture more compressly elongated ; the apex also 

 is more tumid, not so produced. 



Length 7, diam. 4£, m.m. 



33. Achatixa fulica, F e r. Prod. p. 347. 



Deshayes also mentions as found in Bourbon, A. fulva, F 6 r. , 

 this was probably one of the numerous varieties of this Protean 

 species. 



34. A. paxtiiera, F 6 r. Prod. p. 349. 



Deshayes records this species from Bourbon, where I suppose 

 it was introduced as at Mauritius, I did not find it myself. I take 

 the shell, mentioned on the same page as A. purpurea, to have 

 been probably a variety of this species. 



35. Hyalimax malllardi, Fisher, Journ. de Conch. Vol. XV. 



Animal flesh colour, mantle brown, posterior of foot pointed, pro- 

 duced, thickly marked with longitudinal dark brown lines ; 4 dark 

 brown tentacles. The colour often varies in being of a lighter 

 shade throughout. Abundant near Salazie, in damp woods under 

 stones, leaves &c. 



36. Cyclostoma (Tropidophora) tricarixatum, Lam. 

 I only found this curious species at Mauritius, where it is very 



rare and sub-fossil, as extinct there, I believe, as the Dodo. 



37. Cyclostoma fimbriatum, Lam. 

 This, like the preceding, I did not find myself at Bourbon, they 



are both recorded by Deshayes.
