^913- Friend. — Notc^ on Dublin Oligochacts. 171 
Southern has given an account (2). In the mud left by 
the tide, I found a species of Pachyroihd which agrees very 
closely with Marionina gcorgiana, which I have already 
taken in England. Typical Fridericia bulbosa also occurred. 
This is one of the variable species of Fridericia, hence the 
qualihcation. 
Well pleased with my first day's work, I turned inland 
on Prida3^ March 7th, and examined the district to the 
south-west of Donnybrook, giving special attention to the 
earth by the side of the Dundrum road. Here the usual 
Lumbricids were abundant, including such forms as L. 
terrestris, L. rubellus and L. castaneus, with A. longa, A, 
chorotica, and A. caliginosa. The Gilt -tail {Dendrobaena 
stibrubicunda), Brandhng, and the interesting form once 
known as the Celtic Worm {A. celtica), but now recognised 
as D. mammalis, were not uncommon. In the damp soil 
by the runnels, Allurus was abundant, but I could not find 
anything save the typkal form. There were one or two 
Tubificidae and numerous Enchytraeids, including Henlea 
Dicksoni and a species new to science. 
March loth was spent by the side of the canal between 
Leeson Park and Phoenix Park. The worm which was 
years ago found in Dr. Scharff's garden at Leeson Park, 
and named Eisenia hibernica was re -discovered in a heap of 
garden refuse. Vast numbers of Enchytraeus minimus and 
E. albidus were also met with, and a species of Buchholzia 
which was in no instance mature. Here, too, Achaeta 
bohemica was plentiful, as were F. bulbosa, E. Buchholzi, and 
other Enchytraeids. In a ditch beyond Portobello, as 
well as in the mud by the sides of the canal, Tubifex was 
found. It was not common in my gleanings, but two 
species of Limnodrilus occurred, viz., L. Hoffmcistcri and 
L, udekcmiarius and a species of Ilyodrilus. Two cocoons 
of Limnodrilus full of eggs were in fine condition. The 
usual earthworms were found, including Allurus, and some 
species of Fridericia. 
On the nth I visited Sandy mount, but was unable to 
find E. sabulosus described by Southern as occurring there. 
Returning by the canal, which had proved very productive
