Arno, Marshall Islands (an island close to Majuro).
1mm. I've been wrong before but I believe this is adult with formed peristome. Is this Turbinidae, Liotiidae?     -------------------- David Kirsh

It is a Pickworthiidae, and probably Astrosansonia dautzenbergi (Bavay, 1917) .
Below is a link to a pdf of: Le Renard J. & Bouchet P. 2003. — New species and genera of the family Pickworthiidae (Mollusca, Caenogastropoda). Zoosystema 25 (4) : 569-591. http://www.mnhn.fr/publication/zoosyst/z03n4a1.pdf -------------------- Bret Raines

Thanks, Bret. Harry Lee concurs. He sent a response on Conch-L:
Although missing its (precariously upright and elongate) protoconch, it is otherwise an absolutely perfect match for the specimen of Astrosansonia dautzenbergi (Bavay, 1917) in Le Renard and Bouchet (2003: 571; fig. 1). Of further interest is the fact that the authors, who described and illustrated the (taenioglossate) radula, had to compare the shell with the phylogenetically very remote vetigastropods Dentarene and Pterarene. As Andrew warned, there are uncanny evolutionary convergences in shell morphology in these little white skeneiform snails (LWSS). -------------------- David Kirsh
