REV. H. FRIEND ON SOME NORFOLK ANNELIDS. 395 
This time I made careful drawings and notes, and on 
turning to these after exactly twenty years I find that two 
species of fresh-water Enchytrseids were in the bottle. They 
were undoubtedly the same as the 1890 consignment, and 
while one is named Pachydrilns ( Lumbricillits ) subterraneus , 
Vejdovsky, the other is probably P. Evansi, Southern. The 
former of these two Annelids has been received by me from 
Worcester, Nottingham, Birmingham, Edinburgh and else- 
where, and collected by me in Ireland and many parts of 
England. But as great advances have been made in the 
study during the past twenty years, and many new species 
have been discovered, it would be a great pleasure to me if 
naturalists would send me supplies from different localities, 
that I might investigate the matter carefully in the light of 
modern research. I think it possible that the second species 
might prove to be new to science. 
During the year 1892 I had a most enthusiastic corres- 
pondent in the person of Mr. Arthur Mayfield, of 88, Stafford 
Street, Norwich. I much regret that I have not heard of 
him for many years, since it is to him that we owe practically 
the whole of our knowledge of the Earthworms of Norfolk. 
He had been reading some papers of mine (as Dr. Plowright 
had done in 1890) in Science Gossip, and wrote offering his 
services. On receipt of my reply he sent me, under date 
July 6th, 1892, the following : — I walked down to a bit of 
marshy ground near Norwich, and took what I believe to be 
four specimens of Allurus, which I herewith enclose with a 
couple of small worms from a rubbish heap. One of these is 
of a greenish hue ( L . viridis perhaps ?). The three large 
worms are out of the garden.” 
My notes show that four species were contained in the 
box, and these constitute our first authentic record. 
1. Lumbricus terrestris , Linn. 
2. Lumbricus castaneus, Savigny. 
3. Aporrectodea chlorotica, Savigny. 
4. Allurus tetrcedrus , Savigny.
