Description of a new fossil species of Chara.—In a former volume of 
this journal' I described, under the name of Chara compressa, a Chara 
fruit from the Wasatch group or lower Tertiary rocks of Wales, 
Utah. That species was well characterized by being longitudinally 
much depressed, the height being at least one fifth less than the width. 
© apex was obtuse or even slightly depressed and the number of 
spitals, as observed in side view, ten. This was the first North Amer- 
ican species founded upon the ‘fruits,’ and I am now able to add a 
second equally well characterized species.

disolving the limestone in
