[Vol. i. 



the right bank of the Eel River just below Scotia a very fine section 

 is exposed in stream cliffs several hundred feet high. Here the 

 rocks have a great thickness, comparable to that exposed in the 

 Ferndale section, and the beds are dipping at much higher angles; 

 and the belt of country underlain by them is correspondingly 

 narrower. 



Fossils. — Many of the Scotia beds teem with fossils, and in 

 almost all parts of the section shells or fragments of shells may be 

 detected, although in many cases they are difficult to remove from 

 the rock in good condition. From the more favorable beds distrib- 

 uted through the section the writer found fossils which prove the 

 Pliocene age of the series. A few Pliocene fossils had previously 

 been known from Humboldt County and described by Gabb*, but 

 the geological relations of the rocks in which they were found have 

 never been discussed, and so far as the writer is aware no geologist 

 has hitherto examined this interesting field. The few Pliocene 

 fossils described by Gabb from Humboldt Count}' undoubtedly 

 came from the beds which are here designated as the Wild-cat 

 Series. The collections of the writer from the Scotia section, 

 together with some fossils found in the museum of the University 

 of California and still others collected by Mr. A. Carpenter, were 

 placed in the hands of Dr. J. C. Merriam for identification, and he 

 has kindly furnished the following list of species: —
