30. Astartr livnvlata, Conrad. Huntington and Greenport, dredged 

 in five to ten fathoms. Though not uncommon, and 

 though the valves are often found united, we have 

 never obtained this species in the living state; in fact, 

 there is no evidence that it has ever been found alive 

 north of Cape Hatteras. Linsley, who hist detected 



A>tarte lunuiata. it north, and who gave it the name of A. mactracea, 

 had but one valve. Stimpson and Prime, who dredged it at New Bed- 

 ford, fomid it under the same circumstances as ourselves.
