The tube is usually about 30 mm long or less, but may attain 58 mm 

 (from Redondo Beach, in 136-172 fms) ; it is straight or nearly so (pi. 

 49, fig. 5), constructed of very fine, reddish sand particles (pi. 52, fig. 

 21 ) , thin, though not so fragile as those of some other species having simi- 

 lar thickness. Length of the body is 19 or 20 mm to as much as 35 mm; its 

 texture is typically soft, translucent in the posterior third. Cephalic spines 

 have a distinct metallic luster, coppery or reddish ; they are long, flattened 

 through most of their length, taper to fine, attenuate tips that extend well 

 beyond the cephalic plate, but their tips are recurved and bent backward
