In April of this year (1922) a specimen was sent to the Agricultural Department, Armstrong College, by Mr S. Giles of South Shields, along with a note explaining that it had been found “down in the first spit of the soil” in one of a group of allotments there. It was obviously a specimen of a leech, but the specimen was submitted later, to Mr John Ritchie, the Museum, Perth, who kindly identified the species as Trocheta subviridis, and who mentioned that “this gives so far as I am aware, a more northern habitat than hitherto recorded. See Parasitology, vol. III, p. 182.”
