Bulimus aureolus Guppy, 1866 Figs 21A , L7i

Bulimus aureolus Guppy 1866: 49.

Drymaeus (Mesembrinus) aureolus ; Breure 1979: 117.

Type locality.

[Trinidad].

Label.

”Trinidad”; in Guppy’s handwriting.

Dimensions.

"Height 0.6 inch, breadth 0.3 inch" [H 15.2, D 7.6 mm]; figured specimen H 23.2, D 10.71, W 6.2.

Type material.

NHMUK 1866.1.3.8, two syntypes (ex Guppy).

Remarks.

Guppy described this taxon from immature specimens: "The specimens from which the species was described by me in the Annals and Magazine of Natural History (1866) were young and imperfect." ( Guppy 1871: 307). There is another shell (NHMUK 1875.2.8.1), also presented by Guppy, which could be from the series he is referring to in the second paper; it is therefore not considered a syntype since this specimen was later collected than the type series, but unfortunately all three specimens have been mixed and there is no way of separating the two lots.

Current systematic position.

Bulimulidae , Drymaeus (Mesembrinus) aureolus (Guppy, 1866).
