drilus the segregation of the nephridium into several almost

Introduced Worms. — I here append a list of exotic species 

 which we have collected in several localities in the South 

 Island. They have been identified for me by Mr. Beddard 

 and Mr. J. J. Fletcher, F.L.S., the author of several valuable 

 papers on Australian earthworms." 



Microscoles modestus, Rosa (Eiidrilus (?) dubius, Fletcher). 

 Allolobophora rubicunda, Eisen. (Lumbricus campcstris, Hutton). 

 fcetidus, Sav. (Lumbricus annulatus, Hutton). 



„ turgidus, Sav. 



„ purptircus. 



„ rubelhts, Sav. 



Lumbricus terrcstris. 

 Allurus tetraedrus, Sav. 

 Tubifex rivulorum. 



The first-named species is one of wide distribution ; it 

 occurs in Australia, Tasmania, Norfolk Island, and New Zea- 

 land. It was first described by Dr. Bosa, who obtained a 

 single specimen among some soil which had been brought to 

 Genoa with plants from Buenos Ay res. Four months later it 

 was described by Mr. Fletcher as Endrilus (?) dubius, wdiich 

 name must now be regarded as a synonym. There still, how- 

 ever, exists some doubt as to there being one or two species — 

 a larger and a smaller form. Both forms are common in 

 gardens at Ashburton, the smaller one inhabiting garden-soil, 

 the larger form occurring in rubbish-heaps and old heaps of 

 manure. Fletcher gives its measurements at 45mm. to 

 65mm. long, with a " clitellum of a yellow hue." The 

 clitellum of the smaller form occurring at Ashburton is 

 reddish in colour, that of the larger one is distinctly yellow, 

 while some specimens attain a length of 4in. and 4-3rin. It 

 is a robust species, and easily identified by its yellow posterior 

 extremity. 



The second and third species in the above list were 

 described! by Professor Hutton ; his names, however, must 

 now remain as synonyms. Allolobophora turgidus is another 

 remarkable species, having a wide geographical range. It 

 occurs in North America and Mexico, in many parts of Aus- 

 tralia, Tasmania, and New Zealand. It is rapidly spreading 

 and increasing everywhere where gardens are cultivated. 

 Allolobophora imrpurcus is common in some districts in 

 gardens, and A. rubellus occurs in moist soil on swampy flats,
