from which the fossils were taken. The faunas are generally so small, and the strati- 

 graphic notes so incomjalete, that it is not possible to make any definite correlations 

 between these deposits and the different horizons of the San Pedro series. 



Port Los Angeles. — The writer has obtained the following species from a hard, 

 sandy stratum underlying more than a hundred feet of soft, sandy deposits in the mouth 

 of the canyon at the end of the large wharf at Port Los Angeles, near Santa Monica: 



Astijris gausapata Olivella bipUcata Plcuroloma perversa 



Bfla sanct(E-monlc(e Olivella intorta Tapes staminea 



Biitium asperum Ostrea lurida (!) Turritella cooperi 



Nassa mendica var. cooperi Pisaniafortis Trophon scalariformis 



Naxsa perpinguis Pleuroioma carpenteriana Venericardia venlricosa 

 Ntverita recluziana 



The stratum from which the above fossils were obtained is probably Pleisto- 

 cene, corresponding to the lower San Pedro series of Deadman Island, for lithologically 

 and faunally the strata are quite similar. The overlying beds are soft and unfossilifer- 

 ous, and lie slightly unconformably on the lower fossiliferous stratum; and although 

 they contain no fossils, still, from lithological and stratigraphical reasons, it is probable 

 that they are equivalent to the upper San Pedro deposits. These Pleistocene strata ex- 

 tend down the coast from the great wharf to about one-half mile below Santa Monica. 



San Clemente Island. — The post-Pliocene deposits of San Clemente Island are 

 small. W. S. T. Smith' says that they consist of fine sand and rolled pebbles, and 

 have a maximum thickness of only ten feet. Lucina californica is the only fossil 

 shell reported from these deposits. 



Newport. — Much of the coast line from Long Beach to San Diego consists of 

 more or less elevated deposits of Pleistocene age. Deposits of Pleistocene age have 

 been examined by W. L. Watts in the vicinity of Newport, Orange county.^ About 

 a.mile north of the town of Newport is a formation of soft sandstone and yellowish 

 clay-shale, with layers of hard calcareous strata, and some strata which appear to be 

 made up largely of diatomaceous material. These deposits contain the following 

 species, which have been identified by Dr. J. C. Merriam : 



Anemia lampe Crucibulum spinosum Plarunatiornia macroschisma 



Cardiumpanamense[^C'. procerum] Macoma imjuinata Pomaulax undosus 



C'hione simillima Neverila recluziana Tapes staminea 



Chione succincla Peclenii'quisnlealus[1^P. vcntricosus^ Zirphiea crispala [^=Z. Gabbi] 



The fauna given above shows that this deposit is equivalent to the upper San 

 Pedro series. 



The oil-sand and sandstone west of the inner bay at Newport contain the 

 following species:^ 



Biitium asperum Macoma inquinata Olivella biplicala 



Bryozoan remains Monoceros enyonatum Peiricola carditoides 



Crepidula adunca Sassa/ossata Tapes staminea 



Lucina californica Nassa perpinguis 



This fauna corresponds to that of the ui)per San Pedro .series, although no 

 definite relation can be established, owing to the lack of characteristic fossils.
