From forest at George Town were collected 8 examples of a 

 species which do not agree with any of those already described. 

 It is a stoutish worm but short, measuring 49 mm. by 3 mm. in 

 diameter. Such an individual possessed 94 segments. 



The prosiomium is complete. The setce have the usual dispo-
