Naesiotus lycodus ; Breure and Borrero 2008: 13.

Type locality.

"Galapagos, Indefatigable Island, 450-550 ft.".

Label.

"Galapagos, Indefatigable Island, 450-550 ft.".

Dimensions.

"Length of shell 11; diameter 8 mm"; figured specimen herein H 10.0, D 7.3, W 6.2.

Type material.

NHMUK 1937.6.18.11-12, two possible paratypes, CAS expedition leg. 1905-1906 (ex Schlesch).

Remarks.

These specimens are here considered only as possible paratypes, despite the evidence on the label. The reason is that material of Naesiotus snodgrassi (Dall, 1900) was found (NHMUK 1937.6.18.6-7), originating from Schlesch and designated as ‘paratypes’, which proved to be collected by the expedition of the California Academy of Sciences in 1905-1906 according to the label; for that reason it is impossible that they belonged to the type series. All type material from this source is thus viewed with much suspicion.

Current systematic position.

Bulimulidae , Naesiotus lycodus (Dall, 1917).
