1877, op. cit., p. 715, Pl. txxtv, figs. 8-9. Southern end of Lake Nyasa and near the 
small lake Pamolombue of the Shire River. On account of its very flattened spire, 
this species seemingly belongs in a distinct group, for which Bourguignat’s name 
Nyassana would be available.

third page of accompanying letter-press). River Congo. This shell was apparently 
obtained in the Congo estuary by Cranch, the naturalist of the Tuckey Expedition 
(1816). See our remarks upon this species under the treatment of L. intortus 
(Lamarck).
