This list may be increased by the addition of the following 

 forms, which are unrecognisable ; in many cases even the 

 generic name is probably wrong ; these are queried : — 



Acanthodrilus uUginosus, Hutton. New Zealand. 

 1 Dig aster Icevis, Hutton. 

 1 Digaster campestris, Hutton. 

 % Lumhricus annulatus, Hutton. 



PerichcEta sylvestris, Hutton.

 permit of the deduction of any general statements respecting

 U. corethrura. 

 2 Certainly not Lumhricus, as clitellum extends from xiith to xviiith segment. 



? Dichogaster.
