1870.] On the Land Shells of Bourbon, 405 



8. Helix Baeclayi, Bens. (M-ejpta apud Albers). 



This is, I believe, Deshayes' H. Eucleli, both description and 

 figure agree admirably ; the unique specimen, from which this latter 

 was described, appears to have been accidentally broken, whilst 

 being figured. Deshayes says, " from the debris I believe it to 

 have been 6 to 7 mil. in diameter" ; of H. Barclayi, however, I have 

 never found any specimen more than 4 mil. At Bourbon I found 

 this species rather local, on huge boulders, perfectly undistinguish- 

 able from Mauritian specimens. 



Tentacles iron grey, posterior of foot white, the rest of the ani- 

 mal the same, with numerous and regular dark grey streaks, 

 showing very distinctly through the transparent shell in a trans- 

 verse pattern. 



9. Helix Salaziensis, n. sp. 



Shell very minute, somewhat turbinated, horny, thin and fragile ; 

 4^- rather convex whorls, minutely transversely striated, striaa 

 wide apart, acute and presenting, under a magnifying glass, a 

 somewhat lamellar appearance ; widely and deeply umbilicated ; 

 the base rather convex, in young specimens provided with a simi- 

 lar sculpture as on the whorls, becoming obsolete, however, in full 

 grown ones ; aperture small, with the margin of the outer lip 

 simple and acute. 



Diam. 2, Alt. 4 — 5 m.m. 



I have named this minute species after the village near where 

 I found it, about 24 miles up a steep pass towards the centre 

 of the Island. Salazie is extensively used as a sanatarium, 

 on account of the invigorating temperature and some noted 

 mineral water-springs ; it seemed to me, to be one of the most 

 favourable localities I have yet visited in the tropics for the 

 botanist and naturalist : plants and ferns, insects, birds, &c, 

 all seemed equally attractive and abundant. I especially noticed 

 many beautiful Orchids in my rambles towards the old extinct 

 volcano, which towers, some little distance off, at the back of 

 the village, some 11,000 feet above the sea. I found the little 

 shell above described, in company with the preceding, on large 

 masses of rock.
