Body slender, considerably larger at the posterior ex- 

 tremity. Head of tolerable size, rounded, and provided 

 with two narrow, rather hooked horns at its back part, 

 directed backwards. The head is connected to the body 

 by means of a long and very slender cylindrical neck, 

 which is fm-nished with about a dozen constrictions, Avhich 

 make this part of the body appear as if it were beset 

 with an equal number of rings or knobs. 



A short distance beneath the head it is very narrow, 

 gradually increasing in size as it joins the body. Abdo- 

 minal portion small, blunt, and obliquely truncate. The 

 ovarian tubes are very long and slender, about as long 

 again as the whole body of the animal. 



Length of the body about an inch ; ovaries, one inch 

 and a half.
