Nothria elegans^ N. iridescens and A^ pallida are elosely related. 

 Eeologieally they may be reeognized as follows: N. elegans oecupies a 

 limp, thin-walled, sand-covered tube and oeeurs in shallowest benthic 

 bottoms. N. iridescens constructs a tough, chitinized, tightly fitting tube 

 and exists in deeper bottoms. A^ pallida constructs a thick walled, mud- 

 covered tube and occurs in considerable depths.
