Some Notes on Tertiary Fossils of California. Ves 
FALSE BAY. 
Along the shores of False Bay, which bounds the tract known 
as Pacific Beach on the south, are found numerous large 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 I have 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 feet 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 lugubre. Chiton (valves). 
Lottia gigantea. Haliotis cracherodii. 
Acmaea spectrum. Drillia moesta? 
PE Aspelta: Monoceros sp.? 
‘““ scabra Leptothyra sp. indet. 
Gadinia reticulata. , Volvarina varia. 
Fissurella volcano. Bittium sp. indet. 
Calliostoma canaliculatum Cumingia Californica. 
Glyphis aspera. Lucina Californica. 
Crepidula lingulata. Platyodon cancellatum. 
2 dorsata? Zirphoea crispata. 
Petricola carditoides. Septifer bifurcatus. 
Chama exogyra. Pachypoma yibberosum. 
Balanus 3 sp. indet. Strongylocentrotus sp.? 
Vermetus ? sp. Serpulorbis squamigerus. 
This isa 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 zequisulcatus, 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. 
Leaver UpIdC 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 Centrai America. The 
little republic is indeed the most densely populated country in 
both Americas, with exception, perhaps, of some of the lesser
