REV. H. FRIEND ON SOME NORFOLK ANNELIDS. 
401 
one or two excursions lately but have so far not been success- 
ful in finding anything that I have not already sent you. 
To-day I found L. terrestris , L. rubellus, A. chlorotica , and 
A. mucosa (=: E. rosea ) on Household Heath (soil, sand and 
gravel, covered with turf), and L. purpureas (= castaneus ) 
and A. turgida under moss on a hedge-bank at Rackheath 
(sandy loam). To tell you the truth, I begin to feel a bit 
disappointed in not finding A. celtica , I). Bceckii , D. constricta , 
and A. lactea. I think I ought to get at least two of them. 
A damp county like Norfolk ought to produce a larger 
number of species than the fourteen I have found. Do you 
not think so ? ” And thus our correspondence closed tor 
1892. 
I resided for some time in the adjoining county of Suffolk 
several years after this, but my attention was at the time 
diverted from the study of these interesting subjects, and it 
was not till I went to Sutton in 1911 that I was able to do 
anything further in the matter. Meanwhile no one had come 
forward to fill Mr. Mayfield’s place, and a blank of nearly 20 
years intervenes. My researches resulted in the discovery of 
one additional earthworm, viz. : — 
15. Oclolasium gracile, Oerley. 
The curious point is that this worm, which has elsewhere 
only been taken very sparingly — usually one individual in 
each locality — was here the dominant type of Allolobophora. 
It abounded near the eel-traps, and by the landing-stage at 
the Laboratory, and when first taken was, on account of its 
abundance, mistaken for A. caliginosa. A tin canister found 
floating on the Broad, left by anglers, contained about fifty 
specimens of L. terrestris adult and in good condition, but 
weakened by having been kept some time in confinement 
without food. I do not know where they had been originally 
taken. 
The season of 1911 was remarkable for its long-continued 
drought, and even in the Broads worms were exceedingly
