Fig. J, K.

Cyphaspis stigmatophthalmus Richter, 1914 ; Feist and Schindler 1994: 210, pl. 4: 9–15 (see list of older synonymies therein).

Remarks.—This taxon has been variously attributed either to Cyphaspis Burmeister, 1843 or Otarion Zenker, 1833 . Following the revised differential diagnoses of these genera given by Adrain and Chatterton (1994) we attribute the species to Otarion (note that stigmatophthalmus was omitted from the annotated species list of Otarion published by Adrain and Chatterton 1994).

Material.—Figured specimens: 1 cranidium from section “2”, upper trilobite association (UM2− RF 248); Additional material from section “2”, upper trilobite association: 1 cranidium (UM2− RF 249); from section “1”, lower trilobite association: 2 cranidia (UM2− RF 250–251).
