Hancock and Atthey (1870c) in describing this specimen found it "necessary to establish a new genus for the reception of this curious species", which they named Batrachiderpeton lineatum. Hancock and Atthey (1870c) used this skull together with a less perfectly preserved one (NEWHM:G025.37) and a left mandibular ramus (NEWHM:G025.41) to describe their new species. Watson (1913) referred to this specimen as the type of Batrachiderpeton lineatum Hancock and Atthey, and cited it as Specimen I.
