The tooth from California represents a form approaching 

 Elasmognathus bairdii of the Recent fauna in certain characters. 

 In some respects it is intermediate between E. bairdii and 

 Tapirus terrestris. Though the California specimen shows some 

 resemblance to T. haysii, the considerable difference in form of 

 Mo makes it very difficult to believe that the two are specifically 

 identical. The specimen seems at least as near E. bairdii as to 

 any described species, but the nature of the cingida and of the 

 tubercles between metalophid and hypolophid seem to distinguish 

 it from that form. The writer considers that a tentative recog- 

 nition of the distinguishing characters of the California specimen, 

 together with an indication of its geographic location, is more 

 desirable than a very doubtful reference to one of the described 

 species. This form is therefore tentatively distingiiished as 

 Tapirus haysii calif ornicus.

.SPECIMEN FEOM MARINE BEDS AT CAPE BLANCO, OEEGON 



The tapir specimen from Cape Blanco, Oregon, was obtained 

 in June, 1911, by Mr. Bruce Martin while collecting in the marine 

 beds of that region for the California Academy of Sciences. 

 It was found in the bluff about three miles south of Cape Blanco 

 and one-half mile north of the mouth of Elk River. At this 

 locality the formations comprise two lithologic phases: (1) an 

 upper, gray-buff sand, which is loosely cemented and breaks 

 down readily; (2) a lower, blue-gray, argillaceous sandstone, 

 which is better cemented and forms steeper cliff walls than the 

 upper zone. There is no evident discordance between the upper 

 and lower zones. 



A considerable marine fauna obtained from the upper sand 

 by Martin seems quite certainly to represent a phase of the 

 Pleistocene near that of the San Pedro stages. The marine fauna 

 of the lower sand is distinctly older than that in the upper zone, 

 and shows some resemblance to that of the upper Merced series.
