1889.] ON THE OLIGOCHyETOUS FAUNA OF NEW ZEALAND. 377 



mistook them for Impalas, which, however, are not found on the Tana 

 on either bank. 



" It was only when I fired at the Gazelles, and the Hunter's Ante- 

 lopes (a pair of young males) ran away, that I noticed that they were 

 something new to me. They ran with rather a heavy gallop like a 

 Hartebeest. I then had a very long track after them, and managed 

 to kill the young male which I first sent you. 



"We did not come across these Antelopes again for some days, but 

 then met with them in large numbers and got several specimens. 

 They seemed to me to have more vitality than any other Antelope 

 I have ever killed. This species certainly does not extend down to 

 the coast, but we saw them as far as the furthest point we reached 

 (about 250 miles) up the river, at a place called Mussa. Their Galla 

 name is ^ Herola,' not ' Harunta,' as given in your original de- 

 scription (supra, p, 59)." 



5. On the Oligochsetous Fauna of New Zealand, with pre- 

 liminary Descriptions of new Species. By Frank E. 

 Beddard, M.A., F.R.S.E., Prosector to the Society. 



[Received June 12, 1889.] 



The only papers dealing with the Oligochseta of New Zealand are 

 by Baird (4), Dr. Button (8), ^Nlr. W.^V. Smith (15), and myself 

 (1, 2, 3). The papers of Dr. Hutton contain short descriptions of 

 Earthworms, accompanied by a few figures illustrating the form of 

 the prostomiura and the distribution of the setae. The species are 

 all referred to the genera Lumbricus and Megascolex ; but it is 

 quite clear from Dr. Hutton's statement as to their characters that a 

 considerable number of species are wrongly identified with Lumbricus, 

 and that they belong to other genera, especially to Acanthodrilus. 



This is the case with Lumbricus uliginosvs, which is possibly 

 identical with either Acanthodrilus novce zelandicB, A. dissimilis, or 

 vl. ros(S. Lumbricus campestris may perhaps be my Neodrilus mono- 

 cystis ; it is stated by Captain Hutton to possess " male genital 

 openings on the ninth segment. Vulvee on the two last segments of the 

 clitellum." The " male genital openings " are clearly the spermathecal 

 pores, while the " vulvae " are no doubt the atrial pores. luasmucli as 

 Captain Hutton describes the atrial pores of Lumbricus uliginosus as 

 occupying the last three segments of the clitellum, it seems possible 

 that the presence of only two pairs of apertures in L. campestris may 

 mean the atrial pores of the xviith segment and the male pores of seg- 

 ment xviii.,which I have recorded as characterizing Neodrilus. The 

 systematic position of Lumbricus levis is hard to understand from the 

 description given in Captain Hutton's paper. 



Lumbricus annulatus is, as Captain Hutton states, not far removed 

 from Allolobophora fcetida. Having examined specimens from New 

 Zealand of a species which I cannot distinguish ivoin A. fcetida,! am 

 inclined to think that there is no necessity to recognize A. annulata
