Pyxis arachnoides Bell, 1827: p. 395 , pl. XVI: figs 1, 2

Current name: Pyxis arachnoides Bell, 1827

Lectotype: OUM 1092 ( Bell Collection , Catalogue of Testudinata No. 13a; shell, SCL 14.4 cm, bears small label with number “5”or “6”).

Paralectotype: OUM 8528 ( Bell Collection , Catalogue of Testudinata No. 13b; shell, plastral forelobe missing, SCL 12.3 cm, bears small label with illegible number).

Remarks: Bell (1827: pp. 394–395, 397) explicitly states that his description of Pyxis arachnoides was based on two shells in his collection, one of which (now OUM 8528) had lost the movable plastral forelobe. Two further ethanol-preserved specimens (both catalogued under number OUM 8782) must have been acquired later and bear, therefore, no type status. Although somewhat idealized, the carapace figured in Bell (1827: fig. 1) agrees quite well with OUM 8528, while the ventral view (fig. 2) corresponds to OUM 1092. Bour (1978: p. 153) designated the latter specimen as lectotype of Pyxis arachnoides Bell, 1827 .
