The specimens of this species were all collected in one locality, at 

 Race Run, in coarse sand. We did not find it in Provincetown harbor 

 or at Wellfleet, though the conditions seemed to be favorable, and we 

 looked for it with care. At Race Run were obtained numerous speci- 

 mens, but they were all small.
