Fern. Helieidee. 
Succinea, Draparnaud. 
*S. picta, Pfr. — This native of the Island is still to be 
found feeding upon the plants of boxwood (MeUissia begonifolia), 
which grow on Long-range and other south-eastern parts of the 
outskirts of the Island. The ground beneath those bushes is 
covered with its reddish-amber-coloured dead shells. This species 
appears to keep to the lower and hotter climate at an altitude 
of five or six hundred feet above the sea, as it is not found on 
the high land. 
* S . asperula, Pfr. — A native shell, found abundantly in a dead 
and somewhat fossil state in the surface soil on Flagstaff Hill, The 
Barn, and Sugarloaf Hill. The ground under the bushes of 
Samphire ( Salsola salsa) and other scrubwood is covered with its 
pure white, opaque, and bleached dead shells, some of which are 
found embedded in the limestone beds on the south side of Sugar- 
loaf Hill. 
*S. rudorina, Gould. — Still found alive feeding upon the 
cabbage trees and native vegetation which grow on the high central 
ridge, 2600 feet above the sea. It may be distinguished by its 
fyht amber-coloured shell. 
*S. bensoniana, Forb. — Found now only in a subfossil state, 
embedded in the surface-soil. This species is figured and described 
“ Proceed. Geol. Boa,” March 10, 1852, p. 198, pi. v. f. 7. 
*S. solidula, Pfr.— A small species still found living underneath 
and clinging to the rocks and stones on the low land, at New 
Ground, &c., altitude above the sea 1200 feet, where it appears to take 
refuge from the Wire Bird (FEgialitis sancta helence), which inhabits 
those parts and feeds upon it. The little shells of this species be- 
come coated with earth, which, being of the same colour as the rocks 
and stones, serves to conceal them. 
*S. helenee, Forb. — A small species, the delicate little white 
shells of which are found only in a dead state in the neighbourhood 
°f The Barn. 
Helisiga, Less. 
H. sanetse helense, Less. — This very beautiful bright amber- 
coloured creature, a true native of the Island, may easily be distin-
