Description of the Triassic Fossils of California and the 

 adjacent Territories: BY W. M, GABB. 



Of twenty-eight species described, twenty -four are new. 

 We have also a new genus, Rynchopterus, nearly allied to 

 A vie u la. 



Description of the Jurassic Fossils: BY F. B. MEEK. 

 Fifteen species, all of them new. 



Description of the Cretaceous Fossils: BY "W. M. GABB. 



This paper includes the greater part of the volume. The 

 Cretaceous was found by Mr. Gabb to be very largely devel- 

 oped in California, and this gentleman (who, by a long special 

 study of this Formation and its fossils, has become the very 

 highest American authority on the subject,) has worked up 

 with much care the immense material placed at his disposal. 

 Nearly two hundred and seventy-five species are described, of 

 which all but about twenty-five are new. There are also sev- 

 eral new genera: — 



Haydenia, a form between Buccinum and Volutharpa. 

 Whitneya, somewhat resembling Fasciolaria. 

 Tessarolax, very closely allied to Aporrhais. 

 Lysis, general form like Stomatia. 



- Megistostoma, close to Philine. 

 Turnus, belonging to the Teredidse. 



. Cyprinella, allied to Cyprina. 



- Eripliyla, allied to Astarte and Gouldia. 

 Anthonya, belonging to the family CrassateUidse. 

 Meekia, apparently allied to Tancredia, Lycett. 



Following the descriptions in Mr. Gabb's Report, is a valu- 

 able "Tabular Statement of the principal Localities of Creta- 

 ceous Fossils," twenty-seven in number. 



Mr. Conrad has favored us with the following remarks on 

 some of the species described by Mr. Gabb. 



Observations on certain Eocene Fossils described as Creta- 

 ceous^ by Mr. W. M. Gabb, in his Report, published in tJie 

 '■'Paleeontology of California:'^ BY T. A. conrad. 



"Mr. Gabb has included the rock of Canada de las Uvas, 

 which contains Yenericardia planicosta and Aturia zic-zac, in 

 the Cretaceous series, but he has failed to show one Cretaceous 

 fossil from that rock. I think the Eocene also occurs at San 

 Diego, and all the Eocene forms of California that I have 

 seen figured, are such as characterize the oldest members of 

 the period, corresponding to the deposits of Shark River, N. 

 J.; Piscataway and Fort Washington, Maryland; Pamunky
