Type material.

NHMUK 1901.6.22.794-795, two paralectotypes, H. Strebel leg. (Godman coll.).

Remarks.

Strebel gave the measurements of nearly 30 specimens in his description of Bulimulus palpaloensis , but did not mention the material as presented by Martens-who remarked on the label " Otostomus palpaloensis Streb /.../ collected by Strebel". From their remarks ( Strebel and Pfeffer 1882: 86) it is likely that Strebel collected the material himself (see also Martens 1893 [1890-1901]: 223). The specimens found are evidently material studied by Martens and described as his variety hypozonus; this variety is based on Strebel and Pfeffer 1882: pl. 5 figs 12d, 16. No further evidence is given in this paper on which specimens these figures are based. The suggestion in Köhler (2007) that Martens based this taxon on ZMB material is questionable, as Martens 1890-1901 was entirely based on the Godman collection which is now in NHMUK. The current systematic position is according to Thompson (2011).

Current systematic position.

Bulimulidae , Drymaeus (Mesembrinus) emeus (Say, 1830).
