The measurements of the new teeth are somewhat greater than 

 those of the large specimens of Tapiris haysii described by Dr. Leidy 

 from Kentvicky and by Cope from the Port Kennedy Cave. 



Summary. — In taking into consideration the geographic occurrence 

 of the specimen and the very slight degree of alteration in the teeth 

 of the tapir from Oligocene to Pleistocene time, the writer believes 

 that the difference in form between the present specimen and the only 

 previously known lower tooth from California, as well as the consider- 

 able increase in size of the teeth over the described fossil forms, 

 warrants the placing of the specimen in a separate species. He takes 

 pleasure in naming the same in honor of Professor John C. Merriam. 



TERTIARY DEPOSITS OF THE SAN TIMOTEO BADLANDS 



The extensive deposits of the San Timoteo region stretch north- 

 westward from the foothills of San Jacinto some eighteen miles, 

 occupying the divide between the San Jacinto-Moreno and San Ber- 

 nardino valleys, and underlying both to an unknown depth. They 

 consist of a great mantle' of coarse and tine materials, which were 

 spread out from near-by highlands through long undulating cycles of 

 slow gradation and rejuvenation, and were then folded and elevated. 

 During the deposition one great portion at least of the underlying 

 floor sank many hundred feet below the level of the sea. The plateaus 

 and ridges of today are but dissected remnants of the original 

 deposit. In their northern extent the deposits occur as benches about 

 Beaumont at the head of the San Gorgonio Pass, where, spanning the 

 gap between the San Bernardino and San Jacinto ranges, they rest on 

 either side against granite foothills and coarse detrital mountain slopes. 

 In their main extent they form the mesas of Yucaipe and Redlands 

 and the badland ridges to the south of San Timoteo Cafion, a great 

 north-and-south dipping region that plunges in hills and mesas west- 

 ward from the pass into the San Bernardino Valley, and there dis- 

 appears beneath the wash of the Santa Ana River (see fig. Ic, pi. 43, 

 figs. 2 and 3, pi. 44, figs. 3 and 4).
