Type locality.

"provincia Chiquitensi (republica Boliviana)"; see Breure 1973: 118.

Label.

"guarayos, Bolivia"; in d’Orbigny’s handwriting.

Dimensions.

"Longit. a 26 ad 31 millim., latit. 2 ad 14 millim."; in d’Orbigny 1837 [1834-1847]: "Long. 29 millim., lat. 14 millim."; figured specimen herein H 29.7, D 14.9, W 6.2.

Type material.

NHMUK 1854.12.4.132, four paralectotypes ( d’Orbigny coll.).

Remarks.

None of the specimens correspond to the original figured by d’Orbigny. A lectotype-closest to the measurements given by d’Orbigny-has been chosen by Breure from among the material in the Paris museum ( Breure 1975b: 1151). The current systematic position follows Richardson (1995: 145).

Current systematic position.

Bulimulidae , Drymaeus (Drymaeus) linostoma ( d’Orbigny 1835).
