The seventy-six species listed may be taken as representative of the 

 lower part of the Fernando in the Santa Clara River Valley. Of 

 these seventy-six species, there are sixty-six specifically identified, 

 thirty-three of which are living, giving fifty per cent of Recent species. 

 In the Elsmere Canon collection there are fifty species, of which 

 twenty-two, or forty-four per cent, are living. From Holser Canon, 

 out of forty-eight species twenty-seven, or fifty-six per cent, are living. 

 There are thirty-three species common to the two lists, and although 

 the percentage of living species is slightly greater in the collection 

 from Holser Canon, the two faunas are practically of the same age 

 and may be grouped together as a single faunal zone. The Pico Canon 

 fauna also is of the same age as the other two. 



Eldridge 9 in his discussion of palaeontology divides the Fernando 

 group in the Santa Clara River Valley into three faunal zones — a 

 lower, middle, and upper. The writer's work indicates only two main 

 faunal zones, one lowest Pliocene, and the other near the top of the 

 Pliocene or in the Pleistocene. 



The lower zone, as given by Eldridge, includes five localities, all 

 represented by rather small collections, the lists of which were taken 



9 hoc. rit. The palaeontologic work for this bulletin was prepared by Kalph 

 Arnold.
