very minute spines, but the longitudinal bands of muscles were 
not well defined. The segments were mature, but not gravid, 
and were extremely short. Three fairly well defined sizes were 
noticed, for which the following are the dimensions :—

Our specimens measured 4 mm. long, and each consisted of 
about 30 segments. The Jast segments measured °3 mm. long, and 
‘3mm. broad. The neck is I mm. long. The number of hooks 
could not be satisfactorily counted as many of them were missing. 
They measured 03 mm. long. The genital pores are unilateral, and 
are situated in the anterior } of thesegment. The penis is ‘13 mm. 
long, ‘018 mm. broad, and covered with exceedingly minute spines. 
There are six testes. The cirrus sac is situated transversely at the 
anterior and extends two-thirds the distance across the segment. 
The uterus, in gravid segments, consisted of two circular sacs, one 
on each side, which appeared to communicate with each other.
