Succinea pallida Pfeiffer

Pallid Amber Snail (Succinea pallida)

The Pallid Amber Snail was confined to the sister islands of Ra’iatea and Taha’a, where it was historically very abundant and could be found on any moist places on the ground.

The species, which was described in 1847, is now extinct.

Succinea atollica Hertlein & Allison

Atoll Amber Snail (Succinea atollica)

This very interesting species was described in 1968 based on about 30 specimens that were collected on Clipperton Island in the Pacific Ocean apparently 10 years earlier, when the species appeared to be very abundant on the atoll.

The rather unusal shell (for a member of that genus) reaches a length of about 1,1 cm, it is elongately ovate, thin, andr tanslucent, the upper whorls are light amber-colored, the last whorl is grayish-yellow with iregularely spaced brown lines which parallel the growth lines. [1]

***

The Atoll Amber Snail was not found alive since 1958 and it is obviously extinct. [2]

Succinea guamensis Pfeiffer

Guam Amber Snail (Succinea guamensis)

The Guam Amber Snail was described in 1857, it is thought to be endemic to the island of Guam, Mariana Islands.

The species appears to be extinct now.

***

According to another source this species is said to also inhabit Koror, Palau Islands as well as the island of Pohnpei in the Federated States of Micronesia, the specimens collected from there, however, are somewhat smaller that those from Guam. [1]

Succinea rotumana Smith

Rotuma Amber Snail (Succinea rotumana)

The Rotuma Amber Snail is endemic is to the island of Rotuma, Fiji, including at least one of the offshore islets.

The species was described in 1897 based on six specimens that were collected on the island of Rotuma, another specimen was collected in 1938 on the offshore islet of Uea, this is also the last record for this species, that now is considered most likely extinct.

There is, however, the chance that the species indeed survives on Uea or one of the other offshore islets.
