11. RHopoDRILUS MINUTUS, 0. Sp. 
A small species one inch in length. 
Prostomium extending over a portion of peristomial ring, but not 
(2) 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 setze. 
Spermathece four pairs in segments vi.—ix. ; each sac with a single 
diverticulum longer than spermatheca and dilated at its extremity.

Limnodrilus, Claparéde, Mém. Soc. Phys. Genéve, t. xvi. 
13. Lrmnopriwus, sp. ine. 
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 
studying the living worm, I do not feel able to identify the species.

Besides the above-named species, I have received examples of 
Lumbricus and Allolobophora which 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. Parker, 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 Iam 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-
