Bulimus (Thaumastus) insolitus Preston 1909: 509, pl. 10 fig. 9; Breure 1979: 44.

Type locality.

"Chanchamayo, Peru".

Label.

"Chanchamayo Peru".

Dimensions.

"Alt. 70, diam. maj. 29.5 mm.". Figured specimen H 70.4, D 31.2, W 5.6.

Type material.

NHMUK 1947.3.11.1, holotype (ex Preston).

Remarks.

Preston wrote "[a]n extraordinary shell"; the singular implies that he had only one specimen at hand, the specimen thus is the holotype. A label states "Purchased from / Preston many years ago / by Mayor Connolly with / others / A. M. N. H. viii p. 509". The current systematic position follows Richardson (1995: 377) at the species level, the generic classification should be re-evaluated by further studies of the anatomy and by molecular research; this could also affect the arrangement at family level.

Current systematic position.

Megaspiridae , Thaumastus insolitus (Preston, 1909).
