摘要

2019年11月,在圣基茨岛收集了21个完整或破碎的蜗牛壳,记录了陆地蜗牛种类Drymaeus virgulatus (f russac, 1821年)。完整的贝壳是在南弗里盖特湾和梅杰斯湾的后海岸收集的,而贝壳碎片来自北弗里盖特湾砂脊的自然暴露部分,在那里它们可以追溯到前哥伦布时期。因此,这一证据证明了这个物种过去在岛上的存在。在最近的malacology调查中没有发现这个分类群,这表明它已经从圣基茨灭绝了。在圣马丁附近的Tintamarre岛的洞穴中收集到的一个大型bulimulidae的洞穴碎片也与这个分类群有关,增加了第二个西印度岛,这个物种显然在最近几个世纪里消失了。

Drymaeus virgulatus, an extirpated land snail species on Saint Kitts and Tintamarre islands
The land snail species Drymaeus virgulatus (Férussac, 1821) is recorded in St. Kitts in the form of 21 complete or fragmented shells collected on the island in November 2019. The complete shells were collected on the backshores of South Frigate Bay and Majors Bay, while shell fragments come from naturally exposed sections of the North Frigate Bay sand ridge, where they date to the pre-Columbian period. This evidence therefore attests to the past presence of this species on the island. The absence of this taxon from recent malacological surveys points to it having been extirpated from St. Kitts. Apertural fragments of a large bulimulidae collected in the caves of Tintamarre Island, near St. Martin, are also related to this taxon, adding a second West Indian island from which this species apparently disappeared in recent centuries.
