In the “Editors Address,” with which the first number of the 
present series of ‘The Zoologist’ commenced, allusion was made 
to the discovery, a few years ago, of the local occurrence in 
England of Dutrochet’s Land Leech, Trochetia subviridis. had 
hoped that the remarks then made would have elicited from some 
correspondent an account of this little-known annelid, and of the 
circumstances under which it has come to be regarded as indi- 
genous to this country. In this, however, I have been disappointed, 
and nearly a twelvemonth having elapsed without receipt of any 
communication (except a brief note from Dr. Murie), it occurs to me 
to offer the following remarks, in the hope that their perusal may elicit 
some information on a subject which certainly deserves further in- 
vestigalion, and upon which at present comparatively little is known.
