The following report is based upon two collections of ammonoids just brought to me by J.T. Dutro for examination. The only recognizable forms are lirate gastrioceratids, which in the United States are generally lumped together und a single genus, Pseudogastrioceras. In Russia the same shells are referred to four genera: Pseudogastrioceras, Uraloceras, Altudoceras, and in part Paragastrioceras. All of these are Permian. As the Alaskan shells probably belong to a new species, additional material from this locality would be highly desirable.
