Treatment

obeliscus, Helix (Cochlicella), S. Moricand, 1834b: 540 , pl. 1 fig. 4.

Type locality: Brésil, près de Caravelhas [Blanchet]. Holotype: MHNG-INVE-66256 (1) ( Subulinidae ) [ Fig. 68 View Figs 67-79 ].

– Remarks. In the original paper Moricand stated “je n’en connais qu’un seul individu”. The lot found consists of nine specimens, but seems to be a mixture of specimens obtained at different times, as Moricand (1836b: 424) wrote “L’individu que j’ai figuré [in Moricand, 1834b] n’était pas adulte, j’en ai reçu depuis lors qui ont 16 tours de spire, et un autre plus grand encore”. The specimen closely matching the original dimensions has been figured and is considered the holotype.
