Some New or Little Known Oligochata. 31 
incompletely described by Dr Michaelsen, while the other is 
well known. I am able, however, in the present paper to 
record a wider distribution. The species that I deal with 
now are the following :— 
1. Pontodrilus hesperidum, n. sp. 
2. Microscolex nova zelandie, un. sp. 
3. Fridericia antarctiea, n. sp. 
4. Henlea ventriculosa, d Udek. 
5. Cryptodrilus spatulifer, Mich. 
I. Cryptodrilus spatulifer, Mich. 
Cryplodrilus (?) spatulifer, W. Michaelsen, Jb. Hamb. wiss. Anst., vi. 
I have examined a single specimen of a worm which I 
refer to this species in spite of a few discrepancies between 
my own observations and Michaelsen’s statements. 
The specimen was collected some few years ago by Mr 
Lane, who was sent out by the late Mr Berkeley James to 
Chili for the purpose of collecting birds. 
The colour of the preserved specimen was, as Michaelsen 
has remarked, of a dark purple-red dorsally; it measured 
60 mm., and consisted of 93 segments. 
The prostomium, however, is different from that as described 
by Michaelsen; in the worm examined by myself it was 
complete, %.c., it completely divided the buccal segment, 
reaching as far as the boundary line between this segment 
and the one behind. 
The setw are strictly paired, and are visible on all the 
segments of the clitellum. 
The elitellum extended from the xiiith to the xvith segment. 
The nephridiopores open in front of the dorsal pair of sete. 
The male pores are upon the xviith segment. 
There is a gizzard in segment vi.; the intestine begins in 
segment xvii. or perhaps in xvili.; after the xviith segment 
it gradually increases in calibre until a little way after the 
beginning of the xviiith segment. 
The first septwm divided segments vi./vii. 
The testes seem to be present to the number of a single 
pair only ; in any case I could only discover a single pair of
