Some Notes on Tertiary Fossils of Califorjiia. 7/ 



FAI.SK BAY. 



Aloiii^ the shores of False Bay, which iiounds the tract known 

 as Pacific Beach on the south, are found numerous larg^e deposits 

 of shells, formed largely of Donax Californicus in places, and 

 containing remains of echinoderms, besides other mollusks. 

 These need to be studied in connection with those before men- 

 tioned, but 1 ha\'e as yet given them but small attention. 



OCEAN BEACH. 



Ocean Beach lies south of Pacific Beach, with False Bay be- 

 tween them. Both lie within the limits of San Diego city. 

 About two miles south of Ocean Beach, near the top of the cliff, 

 about forty ieet above tide water, I found another exposure in 

 June, 1888, where I made a collection of about fifty species of 

 shells, including those species given in italics in the Pacific 

 list, and the following additional shells. 



Omphalius fuscescens. Hipponyx sp. indet. 



Monoceros Uigiibre. Chiton (valves). 



Lottia gigantea. Haliotis cracherodii. 



Acmaea spectrum. Drillia moesta? 



" pelta. Monoceros sp.? 



" scabra Leptolhyra sp. indet. 



Gadinia reliculata. \'olvarina varia. 



Fi.ssurella volcano. Bittium sp. inOet. 



Calliostoma caiialiciilatiini Cumingia Californica. 



Glyphis aspera. Lucina Californica. 



Crepidiila lingulata. Platyodon cancellatum. 



" dorsata? Zirphoea crispata. 



Petricola carditoides. Septifer bifiirratus. 



Chania e.\ogyra. Pachyponia gii)berosum. 



Halainis 3 sp. indet. Strongylocentrotus sp.? 



Vermetus ? sp. Serpulorbis squamigerus. 



This is a very promising locality, and a much greater variety 

 may be expected after a more careful and thorough examination 

 of the whole exposure — only a small part having been examined 

 by myself 



ROSEVILLE. 



From a cliff at Roseville, nearly east of the Ocean Beach loca- 

 lity and on the shore of San Diego bay, were numerous valves 

 of Pecten ctquisulcatus, Chione simillima and C fluctifraga, im- 

 bedded in the soil a few feet above tide water. Other similar 

 deposits are not rare along the bay shores. C. R. Orcutt. 



THE REPUBLIC OF SALVADOR. 



A little over thirty miles south of San Jose de Guatemala be- 

 gins the republic of Salvador, the smallest, though the second 

 in point of population of the countries of Central America. The 

 little republic is indeed the most densely populated country in 

 both Americas, with exception, perhaps, of some of the lesser
