the richest fossiliferous portions being covered by the con- 

 glomerate. The Coralliochama is fairly abundant in places 

 but is poorly preserved. The following is a list of the fossils 

 found in place and in the bowlders. These fossils as well as 

 those in the other two lists given in this article were deter- 

 mined by t)r. J. G. Cooper. The original descriptions with 

 two or three exceptions were by Gabb.

Although this list contains several species found in the 

 Shasta Group the predominating character is that of the Upper 

 Cretaceous. 



At the northeastern extremity of the point, and about a mile 

 west of Old San Diego, is a bluff consisting of sandstone and 

 some shale carrying casts of Eocene fossils. Quite a variety 

 was found here but specific determinations were in many cases 

 impossible so that the list is not given. The strata dip north- 

 easterly at a small angle and though they cannot be traced by 

 surface outcrops the whole of the distance to the Chico beds at 

 the southern end of the point four miles away, yet judging 

 from the scattered exposures with the same character and 

 similar dip, the indications are that they are conformable with 

 the Chico. The vertical distance between the two fossiliferous 

 beds is probably not over twelve hundred feet.' It would ap- 

 pear that the Chico and Tejon are conformable here as in many 

 other parts of the State, but that there is no blending of the 

 faunas of the two divisions.
