REV. H. FRIEND ON SOME NORFOLK ANNELIDS. 
scarce. I found Allolobophora turgida rare, but L. rubellus , 
A. chlorotica and Allurus were plentiful. In an old tree- 
stump I found D. arborea and a specimen of B. eiseni was 
taken under a decaying tree trunk at Calthorpe. This is the 
extent of our knowledge of the earthworms in Norfolk. 
I sought in vain for that well-known and widely distributed 
water-worm, Lumbriculus variegatus, 0. F. Muller, while at 
Sutton, and should not now be able to report it for Norfolk 
but for the happy circumstance that in March, 1893, I 
received three specimens from Mr. Mayfield taken from a 
ditch at Colney. This, as far as I can remember, was his 
last communication; and I wish here to pay a hearty tribute 
to him for the valuable service he rendered to the natural 
history of Norfolk. 
While working at the Sutton Broad Laboratory I gave 
special attention to the smaller forms of Annelids, such as 
can only be determined by the use of a microscope. Owing 
to the long drought nearly all the ponds, ditches and runnels 
were dry, and as a consequence aquatic forms were rare. A 
day spent at Yarmouth with a view to learning what 
estuarine, marine, or brackish water forms existed, and how 
far inland they could be discovered, was an absolute blank. 
Not a single specimen of any kind was to be obtained owing 
to the drought. On the shores of the Broad, where the soil 
was sufficiently damp to enable Annelids to survive, we met 
with some interesting forms, but it was very disappointing not 
to be able to secure any representatives of the Aeolosomatidce, 
and only two of the Naididce. Of the Tubificidce only two 
species were found, and the greater part of my time was 
spent in working out the Enchytrceidce. 
The most abundant worm, especially among the vegetation 
in the running waters is Slylaria (= Nats) lacustris, Linn. 
The generic name Stylaria , as well as the specific name 
proboscidea which is often used instead of lacustris , each 
point to the most striking peculiarity which this Annelid
