摘要

1963年，对一种罕见的刺猬(狐尾科)Ocajila Macdonald进行了大量先前未被描述的标本，从而对该属的齿列进行了更完整和详细的描述。在此之前，只有一种(型)物种Ocajila makpiyahe Macdonald, 1963年被描述过，并且仅限于不到5个标本。新材料使两个新物种得以确认，来自蒙大拿州惠特尼扬的Ocajila macdonaldi和来自蒙大拿州Arikareean的Ocajila rasmusseni。此外，在蒙大拿州的Orellan中发现了一个不确定的物种，代表了该属的最早出现。

The Hedgehog Ocajila Macdonald, 1963 (Mammalia, Lipotyphla, Erinaceidae) from the Oligocene (Orellan to Arikareean) of North America

ABSTRACT A large sample of previously undescribed specimens of the rare hedgehog (Erinaceidae) Ocajila Macdonald, 1963, allows for a more complete and detailed description of the dentition of this genus. Previously, only the single (type) species, Ocajila makpiyahe Macdonald, 1963, had been described and limited to fewer than five specimens. The new material has allowed for the recognition of two new species, Ocajila macdonaldi from the Whitneyan of Montana, and Ocajila rasmusseni from the Arikareean of Montana. In addition, an indeterminate species is recognized from the Orellan of Montana, representing the earliest occurrence of the genus.

期刊介绍： Annals of Carnegie Museum is a quarterly journal that publishes peer-reviewed short and medium-length original scientific contributions in organismal biology, earth sciences, and anthropology, in 40 by 52.5 pica format (168 by 220 mm or 6-5/8 by 8-5/8 inches). Subject matter must be relevant to Carnegie Museum of Natural History scientific sections or Powdermill Nature Reserve (PNR), preferably with connection to the Carnegie collection and/or personnel. Carnegie Museum staff and research associates receive publication priority, but others are encouraged to submit papers, especially those manuscripts explicitly based on the Carnegie collection.
