Remarks. Wood (1848) described as Chiton fascicularis (?) some valves from the Pliocene Crag of Sutton ( U.K.), with a sculpture similar to that of Acanthochitona fascicularis ( Linnaeus, 1767) [now A. crinita ( Pennant, 1777) , after Kaas 1985a], but more elevated and angular. De Rochebrune (1882) considered this material very different from the known species and proposed the new taxon Acanthochites woodi . The description and figure of Wood (1848) (reproduced here, Fig. 153M View FIGURE 153 ) are not sufficient to identify the species with certainty, and the location of the Wood’s material is unknown, so this taxon should therefore be considered a species inquirenda.

Type material. Holotype: Gottinger Geologischen Institut (Koenen coll.), the tail valve figured by Koenen (1892: figs 23a–c).

Type locality. Latdorf , Magdeburg, eastern Germany ( Lower Oligocene) .

Remarks. No further material of this Oligocene taxon has been found since its original description. A possible attribution to Leptochiton by Janssen (1978). was based on Koenen’s diagnosis, as the holotype was never restudied after. The main features deduced from the original description and figure ( Fig. 153N View FIGURE 153 ), based on a single tail valve, are: depressed valve; sculpture given by thin ribs arranged in groups with discontinuous orientation; absence of tubercles; presence on the ventral side of the valve of a longitudinal furrow which extends from the mucro to the anterior edge; apophyses connected by a lamina. These characters are sufficient to exclude the attribution of this species to the family Leptochitonidae . At present, the generic attribution of this species remains uncertain.
