Bulimulus alternatus hesperius Pilsbry and Ferriss, 1924 Figs 15C, 15iv

Bulimulus alternatus hesperius Pilsbry and Ferriss in Ferriss 1924: 40; H.B. Baker 1962: 10.

Type locality.

[U.S.A., Texas] "east side of the Pecos [river] at the High Bridge".

Label.

"near Pecos river / Texas"; see remarks.

Dimensions.

"34 mm. long, 17.4 mm. diameter"; figured specimen H 34.2, D 17.2, W 7.7.

Type material.

RBINS/MT2353, two probable paratypes, ex Eyerdam, J.H. Ferriss leg., 1924 (Dautzenberg coll.).

Remarks.

Pilsbry and Ferriss (in Ferris 1924) state they have selected a specimen as type, which according to H.B. Baker (1962) is holotype ANSP 84627a. As the label states that the material was collected by Ferriss in 1924, it probably belongs to the original type series. The locality-although more vaguely formulated on the label-corresponds to the area mentioned by Ferriss (1924) for the type series.

Current systematic position.

Bulimulidae , Rabdotus alternatus (Say, 1829).
