Correlation of Tejon Deposits with Eocene stages of the Gulf 
Slope.

‘“VVihile looinparing the Texan Eocene fossiils with type specimens and 
others in the collection of the U. S. National Mnsenm, and in the Phila- 
delphia Academy of Natural ISeienees, I have been impres'sed with the 
reman kable sameness in faunal characters throughout the vast extent of 
the lower iClaiborne, or Lisbon/ horizon ; many of the species from 'South 
Darolina are identical with those from the banks of the iEiio Grande, and 
the rocks .from ,Ft. Tejon, Oalifornia, furnish a very similar fauna with 
several identical and many more analagous species. iGabb’s Cardita hornii 
is Venericardia planicosta Lam. as held by Conrad; the type specimen is 
slightly malformed and imperfect, but others from the same locality are 
quite typical planioosta. Gabb’s At'chitectonica cognata is Conrad’s Sola- 
rium alveatum; Gabb’s Architecionica hornii, Conrad’s Solarium amoe- 
num; Gabb’s Neverita secta, Conrad’s Natica cetites, and so on. Gabb’s 
peculiar and characteristic little Whitneya ficus lis known from Alum Greek 
iBluff, Colorado IRiver, .Bastrop county, Texas, and is in itself a strong 
argument for the synchrony of the Texan and California beds from which 
it is derived. iMoreover, in deposits of this horizon on both sides of the 
Rockies, there are similar developments in the genera Crassatella, Cytherea, 
Pyruda, Levifusus, Rimella and others. 
‘“With the .above facts in mind, I cannot help suggesting that those who 
have an opportunity to study the Eocene iseries of California (Tejon 
deposits) would do well to look for the Midway stage whiclT ranks second 
in persistency among the subdivisions of the Eocene along the Gulf slope. 
In other words, search should be made along the Chico-Tejon contact for 
such species as Enclimatoceras ulrichi, Gucullcea macrodonta, Ostrea pulas- 
Icensis, together with varieties of Venericardia planicosta, Turritella rnor- 
toni, T. humerosa, and other Midway forms.”

“In the following brief report no attempt is made to give a detailed 
account of the organic remains derived from this well. Many of the forms 
.are new and peculiar, and must be carefully .studied, described and fi.gured 
before their introduction into paleontological literature. Many of the well 
known forms present varietal characteTS worthy of minute study and 
description. LAccordingly, the following pages are devoted to the results 
of a study into the relationships existing between the fossils obtained from 
the well and the recent faunte of the Atlantic and Pacific shores of
