Since the foregoing account of _europæus_ was written, a description of the type-skull, with two excellent photographic figures, has been published by L. Brasil,[29] of the Caën Museum. A comparison of the figures with those of the Atlantic City and Long Branch skulls on Pls. 2 and 8 of the present article, confirms the identification of the latter specimens with _M. europæus_. Besides a brief description of the type-skull M. Brasil’s paper contains measurements and two text figures of the right mandibular tooth, natural size. MESOPLODON STEJNEGERI True. _Mesoplodon stejnegeri_ True, Proc. U. S. Nat. Mus., vol. 8, p. 584. Oct. 19, 1885. This species was originally described from a single cranium of a young individual, which was collected by Dr. L. Stejneger on Bering Island, Commander Group, Bering Sea, in 1883. With but a single skull, the characters of the species could not be very satisfactorily defined, and some European cetologists have been inclined to doubt its validity.[30] In 1904, however, another skull was obtained by the National Museum, which made it certain that the species was entirely distinct from _M. bidens_ or other known forms of the genus. Early in the year mentioned Dr. D. S. Jordan, president of Stanford University, called my attention to a small whale, which stranded on the coast of Oregon, 1½ miles south of the United States life-saving station on South Beach, Yaquina Bay, near Newport, in February, and proved later to represent the present species. Doctor Jordan’s information was obtained from Mr. J. G. Crawford, of Albany, Oregon, who wrote him in part as follows, under date of March 7, 1904:
