11. Rhododrilus minutus, n. sp. 



A small species one inch ia length. 



Prostomium extending over a portion of peristomial ring, but uot 

 (?) completely dividing it. 



Dorsal pores present after clitellum. 



Dorsal blood-vessel single. 



Alimentary tract. The gizzard occupies segment v. ; there are 

 no calciferous glands. 



Intersegmental septa separating segments vi.-xii. specially thick- 

 ened. 



Sperm-sacs in segments xi., xii. racemose. 



Nephridia paired, opening in front of third setae. 



Spermalhecee four pairs in segments vi.-ix. ; each sac witli a single 

 diverticulum longer than spermatheca and dilated at its extremity.

12. Tubifex kivulorum, Lamarck, Hist. Nat. Anim. sans 

 Vertebres, t. iii. p. 228. 



Genus Limnodrilus, Claparede. 

 Limnodrilus, Claparede, Mem. Soc. Phys. Geneve, t. xvi. 



13. Limnodrilus, sp. inc. 



A species of Limnodrilus appears to occur very abundantly in 

 New Zealand ; but as none of the specimens which I have examined 

 were sexually mature, and as I have not had an opportunity of

Genus Phreoryctes, Hoffmeister.

 Familie der Regeuwiirmer, p. 40. 



14. Phreoryctes smithi, F. E. B. 



Phreoryctes smithii, F. E. Beddard, Ann. & Mag. Nat. Hist, 

 ser. 6, vol. i. p. 389. 



Besides the above-named species, I have received examples of 

 Lumbricus and Allolobophora wliich I have not yet worked out. 

 Dr. Benham informs me that he has received specimens of a 

 Eudrilus from New Zealand. 



The list of New-Zealand Earthworms which is published in the 

 present paper is principally based upon the examination of two large 

 collections, which were kindly made for me by Mr. W. W. Smith 

 in the neighbourhood of Ashburton, and of one collection which 

 Prof. T. J. Farker, F.R.S., was so good as to forward me from Dune- 

 din. As the same species occurred abundantly in all these collections, 

 I suppose that the list which I am now able to present to the Society 

 contains a fair sample of the earthworm fauna of the country. 



I wish therefore to point out, of course with due reserve, the con-
