NATURAL SCIENCES OF PHILADELPHIA. 19 



But the principal object of the writer of this article, is to furnish 

 a list of localities of remains of fossil elephants and mastodons, 

 to which additions may be made from time to time. 



The writer, during a residence of eight years in California, has 

 spent considerable time in visiting locations where the fossils have 

 been discovered by others, and has succeeded in discovering a 

 number of localities not before known, where fragments of bones 

 and teeth, portions of skeletons, and, in some instances, whole 

 skeletons of the large pachyderms have been found, and has been 

 so fortunate as to discover the onl}^ new species, and, at the same 

 time, probably the oldest mastodon found on the Pacillc Coast. 



List of Localities Fossil Etephas. 



Alameda Comity No. 1. Near Mission San Jose, Elephas Ame- 



ricanus and E. ? Discovered by the writer in post pliocene 



detritus with Mastodon, Lama, Equus, Bos, and a large carnivore ; 

 upper molar deposited in Amherst College ; portion of lower jaw 

 with molar in Yale College, and portion of tusk in Wabash Col- 

 lege. 



No. 2. In Livermore Valley, two large molars of Elephas Arae- 

 ricanus, discovered by the writer in post pliocene with Lama 

 California ? Bos, Equus, Cervus, etc. ; one molar in Wabash Col- 

 lege, the other in writer's collection. 



No. 3. Portion of tusk, from bed of a creek between Haywood 

 and Dublin, formerly in writer's cabinet, deposited in Wabash

Calaveras County. No. L Near Murphy's, in auriferous gi'avel, 

 fragment of molar of Elephas Americanus, discovered by the 

 writer ; deposited in Yale College. 



Los Angelos County. At San Pedro. 



Placer County. No. 1. Near Forest Hill. 



No. 2. Near Michigan Bluff, in auriferous gravel. 



Solano County. No. L At Mare Island, molar. (W. P. Blake, 

 Proc. Cal. Acad. Nat. Science.) 



No. 2. Near Rio Vista, entire skeleton of Elephas Americanus, 

 about seven feet below the surface in clay. The partj' who dis- 

 covered it " went for it" with a pick, and with the assistance of 

 his neighbors, and by dint of perseverance and hard labor, they 

 succeeded in entirely destroying the bones, so that when the 

 writer visited the locality he found a large pile of small fragments, 

 and succeeded in obtaining casts of portion of the right side of lower 

 jaw with molar, and a portion of upper molar; which, with three 

 or four vertebra, comprised all that was taken, and they were so 

 broken that they had to be built up and partially restored in order 

 to get the easts. 



Fossil 31astodon. 



Alameda County. No. 1. Near Mission San Jose, in post plio- 

 cene gravel, the writer discovered an almost entire lower jaw,
