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 furnished with about a dozen constrictions, which 
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.

about the same size at both extremities. The neck is 
long and slender, quite smooth, and destitute of the con- 
strictions which mark so decidedly the preceding species. 
The neck is white, and the body is of a brown, horny 
colour.
