a description of the formation of chalk from Lithothamnia' iu shallow waters 

 in tlie Mediterranean, which gives a solution of various formations in geol- 

 ogy, especially of the more recent chalk beds. Whether it will apply to 

 the extensive structureless chalk beds of western Kansas at all is doubtful.

 northern California. (Bull. U. S. Geol. Survey, No. 33, p. 16, 1880. 

 Washington.) 



The forms come from near Pence's Ranch, and Professor Ward remarks: " If it 

 were certain that the specimen is either Cinuamomum or Palhirus, I should 

 say that it could scarcely have come from a higher horizon than the Mio- 

 cene and more likely from a lower. But the specimen may possibly repre- 

 sent a /'ojjh/«.s _^uulike any modern form. At any rate I would not have 

 been surprised at just such a collection from the Eocene or Laramie group."
