This species is of great interest both on account of its sit- 
gular form, and because it has always been an imperfectly 
known species, without a definite location, either geographically 
or systematically. Pallas stated that his specimens were 
h 
ed to American shells, but with one exception the axis alone

The species described by Prof, Dana, under the same specifi : 
name, has a calcareous axis and belongs to -Juncella. 
minutely granulous with rough irregular spicula, closely united 
together. The spicula are of many forms and sizes,
