This is a very large species, the middle-sized ones resembling 

 in general appearance a large sausage. The two spines on the 

 anterior portion are large and well developed. The hinder portion 

 exhibits only one row of spines, instead of two as in most of the 

 known species. The skin is leathery and smooth; the two ex- 

 tremities are bluntly pointed. The longest specimen we possess 

 is about 16 inches long, the shortest fully 7 inches in circum- 

 ference. 



Hab. We possess five specimens of this species, all from Punta 

 Arenas, on the coast of Patagonia. Collected by Dr. Cunning- 

 ham, of the Surveying Expedition to the Straits of Magellan, to 

 whom we are indebted for several species of Annelides above 

 described.
