Genus Bathraspira Cossmann, 1906 View in CoL
Fig. 2B, C View Fig .
Type species: Cerithium tectum Orbigny, 1842 , original designation; Albian , France .
Included species: The protoconch is known only for Bathraspira pagodoidea ( Kiel, 2006) . All the other species of Bathraspira remain therefore uncertain.
Remarks.—Usually, Bathraspira was assigned to the caenogastropod familiy Procerithiidae (for example Cossmann 1906; Abbass 1973; Kiel 2006). Protoconch and early teleoconch whorls have been unknown until Kiel (2006) described Gymnothilda pagodoidea from the Albian of Madagascar. This species unites a mature teleoconch which is typical for Bathraspira and a protoconch as well as early teleoconch whorls which are typical for Gymnothilda . If the juvenile specimen of this species illustrated by Kiel (2006: fig. 8/1) was found alone, it would be certainly assigned to Gymnothilda . Steffen Kiel (personal communication 2010) also agreed that “ Gymnothilda ” pagodoidea belongs to Bathraspira . It is yet unknown whether this ontogenetic change is also present in other Bathraspira species. In any case, Bathraspira pagodoidea ( Kiel, 2006) is certainly a member of the Mathildidae . Bathraspira sp. sensu Kollmann 1982 (late Early Cretaceous) represents a juvenile specimen consisting of a protoconch and two teleoconch whorls; it shows the characters of Tricarilda . Stratigraphic and geographic range.— Bathraspira is known only from the Cretaceous; France, England, Madagascar.
