FRIEND: NEW YORKSHIRE EARTHWORMS. 89 
thologists, I shall be content to give simply those characters by 
which it can be distinguished from the gilt-tail Owing to the 
distance between the seta, which are so divided as to appear like 
eight separate rows instead of four couples, Eisen made it the type 
of a new genus, and called it Dendrobena. This generic title is now, 
however, discarded, as the gilt-tail, and other species of Al/olobophora, 
have the same peculiarity in a somewhat less marked degree. The 
worm is darker and hardier than the gilt-tail, and somewhat shorter. 
The true position of the girdle in the type appears to be at present 
unknown, for different writers have confused at least three species 
in their diagnoses, and I am just now a little in doubt as to which 
claims precedence. . My specimens have the girdle extending from 
segments 27 to 33, with Zudbercula pubertatis forming a ridge on 28, 
29, 30; but I have other specimens from Northants which are very 
similar in general form, yet appear to be the same as 4. arborea Eisen, 
which has only recently been split off from A. doeckii, and was largely 
accountable for the confusion which has existed. I have taken 
the Tree Worm near Carlisle, and have recently received it from 
Perea I need more material for settling the question 
definit 
I gots found the golden variety of Ad//urus at Calverley 
during the past year, which must be added to the record in 
‘The Naturalist,’ 1891, p. 1 
In 1880 Oerley, a Hungarian naturalist, described a new worm 
aS variety Zacteus of the common earthworm (Lumbricus terrestris L., 
var. dacteus Oerley) as occurring at Buda-Pesth. Now, no true 
Lumébricus is other than a dark, purplish colour, and Oerley’s worms 
have in more than one case been found to belong to the genus 
Allolobophora, though named by him Lumbricus. This variety is one 
of those which come under this head, and I have therefore named it 
Allolobophora lactea n. sp. It is not only new to Yorkshire, but new 
to Britain, and was found by me at Apperley Bridge, at a spot which 
has yielded some very valuable results to my careful and repeated 
investigations. I can do no more here than place the worm on 
record, because, while I have abundant material for determining the 
species absolutely, I am disposed to think it is either identical with 
or closely allied to Allolobophora longa Uhde—a species which 
abounds around Carlisle, and this point will be determined in my 
Series of articles on critical species 
I append a revised and entaried list of all the species of earth- 
Worm at present known to me as occurring in the North of England, 
but I still have materials on hand which will yield some additions to 
—— when properly worked up.
