Bulinus derelictus Broderip, 1832 Figs 10H , L17vii

Bulinus derelictus Broderip in Broderip and Sowerby I 1832b: 107; Reeve 1848 [1848-1850]: pl. 23 fig. 151; Neubert and Janssen 2004: 208, pl. 6 fig. 65.

Type locality.

"Cobijam Bolivia [now Chile] (Puerto del Mar)".

Label.

"Bolivia S. America", with a taxon label in Pfeiffer’s handwriting. M.C. label style I, V.

Dimensions.

"Long. 6/12, lat. 5/8 poll. [H 12.7, D 15.8 mm, see remarks]"; figured specimen herein H 30.3, D 18.8, W 6.6.

Type material.

NHMUK 20100609, four probable syntypes (Cuming coll.).

Remarks.

Broderip described this taxon from the Cuming collection, but did not state on how many specimens his description was based. The original measurments seem to be erroneous, as these indicate a height/diameter ratio uncommon for this genus. Neubert and Janssen (2004) reported three specimens, with a maximum height of 23.1 and diameter of 15.3 mm, labelled ”Peru” (ex Cuming), which they consider syntypes. The specimen corresponding to Reeve’s figure has been found in the NHMUK collection, together with three others; they are considered probable syntypes.

Current systematic position.

Bulimulidae , Bostryx derelictus (Broderip in Broderip and Sowerby I 1832).
