[Eeceived January 12, 1887.] All the specimens collected by Mr. Johnston were from an altitude of from 7000 to 8000 feet. Of the seven species one only appears to be new. This is not surprising, as Dr. Buchholz made fine collections in very much the same region some years ago, which were described by Dr. E. von Martens1. The species are :- 1. Vaginula pleuroprocta, Martens. 2. Helicarion plicatulus, Martens. 3. Helix (Trochonanina) percarinata, Martens. 4. Stenogyra retifera, Martens. 5. Stenogyra oleata, Martens. 6. Streptostele buchholzi, Martens. 7. Gibbus (Edentulina) johnstoni, sp. nov. The first two species were met with by Buchholz at Aburi on the Gold Coast, the next four at Bonjongo in the Cameroons Mountain. The following is a description of the new species of Gibbus:- GIBBUS (EDENTULINA) JOHNSTONI. Testa anguste umbilicata, ovata, subtenuis, nitida, grisea; anfractus 6i, celeriter crescentes, convexi, superiores regulariter arcuatim et confertim striati, penult, et ultimus obsolete striati; apertura inverse auriformis, albida, longit. totius -f 1 Monatsb.
