These late-surviving Leptomerycidae belong to the species Pseudoparablastomeryx scotti and P. francesita, previously assigned to the Blastomerycinae. Likewise, Pronodens silberlingi from Arikareean deposits in Montana and possibly South Dakota is transferred to the Leptomerycidae from incertae sedis in the Cervidae. The relationships between these late Leptomerycidae and contemporaneous Blastomerycinae are shown to be remote despite several parallel features in common. Separation of the family Leptomerycidae from the family Hypertragulidae is advocated"--P.
