 specimen, consisting of 35 segments, measures 75 mm. in length 

 and 18 mm. in breadth at 15th segment. The largest one ever

 segments. This small specimen is perhaps a young animal. 



Prostomium small, dorsally almost wholly occupied by the

 lateral tentacles about .V the length of the median tentacle, wliich

 Caruncle large and rugose, consisting of an elevated, doubly cre-

 interrupted brown line. The caruncle, fixed to the first two para-
