Hab. Hermite Island, Cape Horn ; growing with J. colorata.
Cæspites vix ¼ unc. lati, pallide straniinei. Folia pauca, alterna, nisi apicem caulis versus remota.

It is smaller and has more tumid leaves than any of its congeners ; the latter resemble in fonn the shell of Helix putris, whence the trivial name.
