A single proximal phalanx (figs. 5a and 5b) from the Tejon Hills 

 collections is similar to Meryeoclus phalanges from the Barstow fauna. 

 It seems slightly more slender and smaller than the average of the 

 Meryeoclus phalanges from the Barstow fauna, but is not shorter than 

 the smallest. It is perhaps slightly more slender than the Ricardo 

 specimens. The form represented by this bone may be specifically 

 distinct from M. necatus, the Barstow species. 



These Meryeoclus specimens evidently represent a faunal stage 

 later than early Miocene and earlier than late Lower Pliocene. 



EHINOCEROTID OE PROBOSCIDEAN TOOTH FRAGMENT 



A small fragment of a large cheek-tooth (fig. 6) with thick enamel 

 was at first considered to represent a proboscidean of the Tetrabeloclon 

 type. The structure of the enamel is in some respects more like that 

 in forms of the rhinoceros group.

 the southern end of the San Joaquin Valley, California.

ISURUS, near PLANUS (Agassiz) 



A well-preserved shark tooth (fig. 7) represents a form near Isurus 

 planus described by Agassiz from Ocoya Creek, or Poso Creek, Cali- 

 fornia. This species is also reported by Jordan 4 from the "Temblor" 

 near Bakersfield, California.
