(i) Allolobophora piitris Hoffm. (This apparently is the same as Kinberg's 

 " Hypogaeon havaiaim") 



(2) A. foetida (Savigny). 



(3) A. caliginosa (Savigny). 



(4) A. nordenskioldii Eisen.

PoNTOscoLEX Schmarda. 



Pontoscolex hawaiiensis Beddard, P. Z. S., 1896, p. 196. 



The ubiquitous genus Pontoscolex occurs in the Hawaiian archipelago. I formed a 

 new species for the representatives of this genus which were collected by Mr Perkins 

 chiefly on the ground that the dorsal vessel was usually double for a certain extent. 

 Dr Michaelsen has criticised my conclusion ; and it may be that he is right. In any 

 case the genus and species which are at least hard to distinguish from the South 

 American P. corethriirus occur in the most widely separated regions of the globe. 

 Dr Eisen however' has lately commenced a detailed study of this genus, so that the 

 matter of the specific identity or difference of the specimens of Pontoscolex found 

 scattered over the world had better be left alone for the present. 



Amvntas Kinberg. 



The main earthworm inhabitants of this archipelago belong to the genus Atnyntas 

 as I think (following Michaelsen") it should now be called. The much better name 

 Perichaeta was used for a Dipteran genus before it was applied to an earthworm ; and it 

 appears to me, in spite of the ingenious protest of Horst', that there is no way of escaping 

 from the conclusion that a name once used cannot be resuscitated. One unrecognisable 

 species ''Perichaeta corticis" has been described by Kinberg^ The remaining species 

 are the following : —
