This species is closely allied to Arenicola marina, but has only (> setigerons segments anterior 

 to the gills, iiud 11 gill-bearing segments instead of 7 and 13. as in .1. marinn. These numbers are 

 constant in the five specimens obtained. 



The <! abranchiate segments are each composed of ."> distinct aitmilations. and each bear a pair 

 of simple tubercular feet. The dorsal seta' are all of one kind, about IN in number: slender and 

 slightly serrulate, the longest longer than the foot. The ventral seta- are .'!.", to 10 in number, and 

 form a single row on each side of the ventral surface of the ring. They are .-liort, .-lender, and 

 simple, and barely project above the surface of the skin. 



The branchiate segments arc each composed of li annulations. Each brauchia consists of one 

 cluster of about 15 simple cirri aniiiilated in contraction. The bram-hia- increase in .size from the 

 first to the ninth pair: the. tenth and eleventh pairs are slightly smaller. The, feet are small and 

 tubercular; the dorsal seta-, 7, similar to those of the abranchiate segments, but only about two- 

 thirds of their length. The ventral setie are the same as in the abranchiate segments. 



The caudal portion is about one-third of the length of the animal, without tubercles or other 

 appendages. 



Color, in alcohol, blackish gray, lighter on the ventral surface. 



Five specimens were picked up on the beach, after a fresh westerly wind, September li' and 13, 

 1882. 



A couple of mutilated specimens were also obtained from the gullet of an eider duck which 

 had been diving on one of the sandy patches in about 3 fathoms just above the station.
