The specimens separated under this name, in Mr. Cum- 

 ing's collection by Dr. Chenu, from A. vaginiferum are 

 longer, agglutinated with finer sand, with the disc larger, 

 and frill less tubular, It is extremely doubtful however 

 whether any value can be attached to these points of dif- 

 ference.
