a smaller thinner variety than the ordinary Mascarene ones, very 
seldom having a brown band on the last whorl. 
2. Hexitx (Conuxus), n. sp.? 
From Mahé, Félicité, and Silhouette. Rare; amongst dead leaves, 
&c., in damp places. 
3. Hexix (Discus) serratus, H. Ad., n. sp. 
From Mahé, Praslin, and Silhouette. Uncommon; on the ground 
in moist places. 
4. Hexrx (Discus), n. sp. 
From Silhouette. Very rare. 
5. Hexix (Stytoponra) unrpEentata, Chemn. 
From Mahé, Félicité, Silhouette, and Curieuse. On the ground, 
amongst decaying leaves of the ordinary Cocoa-nut tree, &e, This 
species is not found at all at Praslin. ‘The variety from the three 
latter localities, as given above, differs from the Mahé typical form 
in being thicker, more produced, with a strongly marked brown 
band round the last whorl, and in often being deformed. This spe- 
cies, even in its youngest stages, can be readily distinguished from 
Styl. studeriana, the spiral strize on the first few whorls not being 
cancellated, as is the case with the latter species ; it is also far more 
globose, &c. &c. The animal is a uniform brown, varying in shade ; 
the foot underneath is greenish, and the tentacles a purplish grey, 
6. Hexrx (Srytoponta) sruperrana, Feér. 
From Praslin only. This species is remarkable from its being 
restricted to one island, like the extraordinary tree the Coco-de-mer, 
on whose leaves and trunk it lives; unlike the preceding species, I 
never found any live specimens of it on the ground. ‘There are two 
varieties, one a rich brown colour, the other a decided yellow. In 
shape it always appeared to be perfectly constant; and the reflexed 
outer lip is always white, whilst in Styl. unidentata it is violet-— 
although I procured one specimen of the latter in which it also was 
white, 
7. STREPTAXIS SOULEYETIANA, Petit. 
From Mahé, Praslin, and Silhouette. In damp places, on the 
ground. Animal ash-colour, the posterior part greenish yellow, 
stained on the neck with mauve (varying in shade), foot (underneath) 
yellow, tentacles black. 
8. Ennea (ExmA) neviiut, H. Ad., n. sp. 
From Mahé and Silhouette. Extremely rare at the first-men- 
tioned locality, more plentiful at the latter; on the ground, amongst 
dead leaves &e.
