Ophiomusium jolliense McClendon, 1909 . Ophiosphalma jolliense Hendler, 1996 .

Holotype: MCZ 7048 (this specimen was labelled “ O. clarkii McClendon ” - there is no such species and I assume McClendon decided on a different name for his species after writing the label. No locality data was on the label, but five examples of this species were collected at stations off southern California in 115–603m (D.L. Pawson pers.comm.), of which one must have been McClendon’s type. More recently, Hendler (1996) has recorded O. jolliense from the same areas off California.

Main features: Disc with many imbricating plates both dorsally and ventrally. Radial shields separated by 4–5 plates. Large interradial plate visible only dorsally. Oral shield indistinct, genital slits long, reaching to end of third arm plate. Three pairs of exposed tentacle pores.

Oral papillae not separated. Cluster of small tubercles around arm bases. Dorsal arm plates longer than wide, throughout arm.
