THE UNKNOWN TeELLINa. Shell white, 
oblong-ovate, minutely concentrically 
smooth in the middle; posterior side rather the 
compressed, 
wrinkled,

small, partly imbedded.

It is not without hesitation that this shell is here 
named and described; for although no known species 
appears to correspond with it, yet it bears a rather dubious 
appearance of being the young of a larger form.

I regret to find that a variety of 7. chlorolenca has been 
figured and described under this name as species 51. It 
is a much narrower shell.
