anatomy of Earthworms. The extraordinary reduction in size of 

 the spermatheca? in the new species A. vinjo must therefore 

 be considered as one of the more important new facts which 

 1 detail here. It is interesting to notice that the reduction in size 

 is apparently not accompanied by a reduction in number, and 

 certainly not by an increase in number, as with the small but 

 numerous spermathecse of such a form as Miwochceta. 



The marked resemblance in A. biporus between the " genital 

 papillae " of segmeut xix. and the male pores, confirmed by micro- 

 scopic investigation, seems to indicate the remnant of a second 

 pair of spermiducal glands, which is new to the genus. 



In other respects the species represented in the collection show 

 no particularly noteworthy divergences in structure from other 

 species of Amyntas. 



We shall now proceed to the description of the new species, 

 after mentioning the forms alreadv known to science. 



*6 



(1) Amyntas posthumus ' Vaillant. 



(2) Amyntas cingulatus ' Vaillant. 



These two species, the latter, as I believe, with many synonyms, 

 are so widely spread, and have been so frequently reported upon 

 and described, that I have nothing of novelty to add to existing 

 descriptions. 



(3) Amyntas bossch* Horst. 



PcricJuda bogschce, Horst, Xotes Leyd. Mus. xv. p. 324. 



Perichceta bosscluv, Michaelsen, Abh. 8enck. Ges. xxiii. p. 238. 



Amyntas bosschce, Beddard, P. Z. 8. 1900, p. 625. 



It is rather curious that the collection contains a number of 

 specimens of a species of Earthworm which really does appear to 

 be identical with A. bossclia-. It is at least extremely near to that 

 species, and I do not attempt at present to separate it. Nor do I 

 give a full description, since that has been done. In size aud 

 general external appearance A. bosscJue is very like A. pulanensis, 

 which I describe later ; but it has no genital papillie. 



I find, as did Michaelsen. that there are three pairs of sperm-sacs 

 in segments x.-xii. The spermiducal glands, however, are not 

 compact and small ; they extend through segments xv.-xx. and 

 are much broken up into lobules. Their short duct is coiled into a 

 circle or is perfectly straight. The spermathecae agree rather with 

 Michaelsen's than with Horst's description.

I have examined two specimens which are undoubtedly referable
