Purely consequential recommendations (e. g., 

 Tatu for the tatous^iasiMrMS for the Ameri- 

 can hairy-tailed hats), are not inserted in the

Notes to the List 



1. Oercopithecus has been invariably used 

 for the gueonons up to 1911, and its transfer 

 to the tamarins only depends on Gronovius, a 

 doubtfully binomial writer. 



2. Daulentonia is almost unknown to gen- 

 eral writers, the use of Chiromys having been 

 nearly universal. 



3. The names objected to are both known in 

 connection with other animals, and the use of 

 either of them for the paca is most confusing. 



4. Technically Dasypus ought to be trans- 

 ferred to the tatous. 



6. Echidna has been used by all classes of 

 writers. It would have to be withdrawn from 

 ichthyology. 



6. The use of Cynocephalus involves a par- 

 ticularly objectionable transfer. 



T. An early reference by Pallas in connec- 

 tion with Oryx gazella makes it advisable to 

 affix the name Gazella to the gazelles before 

 it is attempted to be used for the gemsbucks. 



8. The transfer of the name Callithrix from 

 the titi monkeys {Callicehus) to the marmo- 

 sets is highly confusing. The name should be 

 dropped altogether. 



9. Hippotragus has been widely used; 

 Ozanna is practically unknown. 



10. The use for the mountain chinchillas of 

 Vizcaccia, the vernacular name of Lagostomus, 

 is most objectionable. 



11. By the technical rules Nycteris would 

 have to be transferred to the American hairy- 

 tailed bats (Lasiurus). 



12. Hydrodamalis is almost unknown to 

 writers of any class. 



13. Specific name (satyrus) to be fixed as 

 well as generic, the original Simia satyrus 

 Linn, being a chimpanzee.

THE IONE formation OF THE SIERRA NEVADA 



FOOTHILLS, A LOCAL FACIES OF THE 



UPPER TEJON-EOCENE 



One of the numerous problems of California 

 geology is the correlation of the Tertiary (the 

 superjacent series), of the Sierra Nevadas 

 with the Tertiary of the Coast Ranges. Many 

 geologists have written on the age of the aurif- 

 erous gravels and their associated formations 

 since the time of Whitney, but the age of these 

 formations is still in question and their rela- 

 tion to the marine deposits of the Coast 

 Ranges is improved. 



While collecting during the past two years 

 for the department of paleontology, University 

 of California, the writer has had opportunity 

 for the study of the relationship of the lone 

 of the Sierra Nevadas with the marine Eocene 

 of the Coast Ranges. His conclusions are 

 based upon visits to four typical lone local- 

 ities, viz., Marysville Buttes, Sutter Co., Cal., 

 vicinity of Oroville, South Table Mountain, 

 Merced Falls, and the type locality near the 

 town of lone in the Jackson Quadrangle. 



The conclusion from this study is that the 

 lone, in part at least, is marine and of Tejon- 

 Eocene age. Marine fossils have been found 

 in the upper portion of the lone formation at 

 Marysville Buttes, Oroville, South Table 

 Mountain, Merced Falls and lone. Appar- 

 ently the same faunal zone, the Siphonalia 

 sutterensis zone,^ is represented. 



In the study of the Eocene of the Marys- 

 ville Buttes the writer's conclusion was that 

 " the supposed marine lone of MarysviUe 

 Buttes is evidently Eocene." In the " Note 

 on the Faunal Zones of the Tejon Group," 

 the strata beneath the Older Basalt of Oro- 

 ville South Table Mountain which Lindgren 

 mapped as lone, were correlated with the 

 Eocene of the Marysville Buttes. Several of 

 the fossils obtained from the strata beneath 

 the Older Basalt were identical with those of
