IRISH OLIGOCHAETS. 
BY REV. HILDERIC FRIEND, F.R.M.S. 
In a recent issue of this Journal^ I gave some account 
of the annehds found in earth attached to Primula roots 
from Poyntzpass. After my examination in May, I placed 
the material (eartli and decaying roots) in a tin box, and 
set it aside till the end of September. Meanwhile I had 
been studying the seasonal order of appearance^, and, as 
my second examination of the Poyntzpass earth throws 
further light on the subject, I think it desirable to give an 
account of what I have found. My first report show^ed 
no fewer than eight species of annelids to be present in 
the small quantity of earth received. I removed all the 
specimens I could find, leaving the earth, ae^ far as could be 
ascertained, free from oligochaets of every description. 
It was, therefore, with no little surprise that I found, after 
the lapse of four or five months, no fewer than nine species 
of annelids present. These, moreover, were not all of 
the same species as previously reported, but consisted of a 
number of new species, one of which seems to be new to 
science. I give them in the order in which I found them 
and at the end will be found a complete list of the species. 
The earth has again been set aside to see if any further 
results may be obtained. 
1. Dendroba3na subrubicunda, Eisen. 
One adult and two young specimens found, in addition to those reported 
in September. A cocoon also seen on September 24th, but next day 
the cocoon seemed to have yielded a young worm, which was returned 
to the box with the two young ones, to await development. The cocoons 
of this species are green, and about the size of a mustard seed or smaller. 
2. Fridericia bisetosa, Levinsen. 
Three further specimens of this species were present. Length about 
10 mm., segments about 50. White to the naked eye, but brownish under 
the microscope. Setae 1-2 with blunt external points ; bent within. 
Spermatliecae with fairly long ducts and two diverticula. Salivary glands 
slightly branched ; brain straight or slightly convex before and behind, 
appearance varying with tension.
