Canid and Proboscidean Remains from the Ricardo Deposits, Mohave Desert, California

Among the canid remains obtained by University of California collecting parties in the upper portion of the Ricardo beds of the Mohave Desert were several specimens provisionally referred by Merriam to the genus Aelurodon. A maxillary fragment with posterior cheek-teeth, No. 21507 U. C. Coll., furnished the type of the species Aelurodon? aphobus Merriam. A second specimen, a mandibular ramus, No. 22470 U. C. Coll., with well-worn teeth was regarded by Merriam as possibly belonging to Ae.? aphobus, this relationship being suggested by the size and proportion of the teeth in the latter form.
