New Zealand Earthworms. 137 



incorrect ; and since Beddard's series of papers upon the New 

 Zealand worms it has become a certainty that most of Ilutton's 

 species belong in all probability to Acanthodrilid genera. 



Consequently, soon after my arrival in Duuedin, I took the 

 opportunity of examining the " types," which I discovered in 

 a storeroom in the Otago Museum. 



Hutton described six species, of which he placed four in 

 the genus Lumbricus and two in Megascolex. In a subse- 

 quent paper * he suggested that L. uliginosus belongs to 

 Acanthodrilus, and some of the species of the former genus 

 were probably members of the genus u D igaster " though upon 

 what ground it is difficult to say. As will be seen from the 

 following account, Hutton has sometimes confused two or 

 more distinct worms under one name. I append a list of 

 his species, so far as it is possible to identify them, and then 

 give some details as to the individuals : — 



(1) Acanthodrilus uliginosus, Hutton. 

 Syn. Lumbricus uliginosus, Huttou. 



(2) Neodrilus monocystis, Bcddard. 

 Syn. Lumbricus campestris, Hutton, partial. 



(3) Lumbricus rubellus, Hoffuieister. 

 Syn. Lumbricus campestris, Hutton, partial. 



(4) Allolobophora caliginosa } Savigny. 

 Syn. Lumbricus levis, Hutton, partial. 



(5) Octochcetus (?) leois, Hutton. 

 Syn. Lumbricus levis, Huttou, partial. 



(6) Allolobophora jostida, Savigny. 

 Syn. Lumbricus annulatus, Huttou. 



(7) Plagiochceta sylvestris, Huttou. 

 Syn. Megascolex sylvestris, Hutton. 



(8) Plagioc/ueta lineata, Hutton. 

 Syn. Megascolex lineatus, Hutton. 



(1) Of the six "types" I have been able to examine in 

 detail only five; but 1 cannot discover the original of li Lumb.
