HULEN CREEK AND ONO COLLECTIONS. 



251 



Of the 36 species in this list, the Paleontology of California gives 8 as 

 coming from the Shasta and 18 from the Chico, while 2 of the others are 

 doubtfully referred to the former and 2 to the latter. At least 12 of these 

 species are also represented by identical or very closely related species 

 in the Queen Charlotte islands (lower shales), and 7 are similarly repre- 

 sented in the equivalent of the Chico on Vancouver island. 



It will be remembered that Horsetown is a typical and well known 

 Shasta locality, and that the types of two of Mr Gabb's species were 

 obtained there. 



Many of Mr Diller's localities for fossils are on Cottonwood creek and 

 its branches, a few miles southwest of Horsetown. It will be instructive 

 to group together some of these places and consider the fossils that were 

 obtained from them. On Hulen creek, and near its mouth on Cotton- 

 wood creek, the following were collected : 



Ammonites bated, Trask. 

 Ammonite* hoffmanni, Gabb. 

 . Immonites remondi, 

 Turritella. 

 Cytherea. 



Trigonia evansana, Meek. 

 Trigonia tryoniana, Gabb. 

 Nemodon Vancouver ends, Meek. 

 Cucidlsea truncata, Gabb. 

 Pecten opercuHformis, " 



This collection adds two Shasta and two Chico species to the Horsetown 

 and Texas springs list. 



At and about Ono, California, mostly within a mile of the village, the 

 following species were obtained :
