which were unfavorable to the Strophias, so they gradually died. 
The remains were scattered quite regularly over the entire 
surface of the key, but, judging from specimens examined, they

site of the Indian well, of which I have spoken.

DESCRIPTION. 
Sp. Ch. Size medium. Shell, heavy. Striations, present. 
Whirls, nine. 
Form of shell, rather oval, the first and second whirls being 
about equal in diameter. Then the shell 
slopes to a quite acute point, forming an Fig. 47.

others, hence the striations present a 
peculiarly broken appearance ; they are 
partly rounded, and although not

them. 
Aperture, not large, well arched above, and very slightly com 
tracted at the entrance. Lower tooth, not very prominent, about .02 
high, and about twice as long as high, width about equaling height ; 
its position is about central, and slightly elevated. Upper tooth, placed 
quite high, considerably above the top of the lower tooth, is about one 
half as large as the lower. 
Margin not produced forward quite as far as the diameter of the 
shell, is placed a little to the right of the center of the shell, and is 
very slightly inclined to the right ; it is about twice as thick as the
