120 THE ZOOLOGIST. 
2. Limnodrilus udekemianus, Clap.—Received from Ballintoy, 
Ireland, and reported in ‘ Irish Naturalist,’ 1897. : 
3. L. wordsworthianus, Friend.— A species new to science 
found by myself in a pond at Old Carlisle, Wigton, Cumberland. 
It lives in mud at roots of plants, and when taken coils up 
as Tubifex does. When examined under the microscope the 
absence of capilliform sete at once shows it is not T’ubifex, while 
the fact that it has more than two sete in each anterior bundle 
differentiates it from Stylodrilus, a worm which is moreover 
readily distinguished by its appendant penis. ‘The worm is from 
two to three inches long, but owing to its habit of coiling up is 
very difficult to measure. Four to six forked sete are found in 
each of the front bundles. The blackish chloragogen cells begin 
in segment v. These cells often become detached and float in 
the ccelomic fluid. They are globular, and when injured burst 
and dissolve into a thousand tiny specks. ‘The first nephridium 
lies in segment vii. Dilated hearts in vili-ix. The tail, as in 
most Tubificids, lighter in colour than the rest of the body. A 
pair of trumpet-shaped penis-sheaths about four (or five) times 
as long as broad. In the living worm the brain appears almost 
circular, or like a square with the two hindmost angles rounded 
off. It changes in appearance, however, with every new move- 
ment of the worm. Eggs were found in as many as six segments 
or more. A remarkable feature is found in the delicate papille 
with which the peristomium and fore part of prostomium are 
covered. I have named it after the poet, because I had the 
honour to be President of the Wordsworth Institute (in his birth- 
place) when the worm was discovered. 
4. Hemitubifex benedii (D’udekem).—Received from Malahide, 
Ireland. . 
5. Branchiura sowerbu, Beddard.— Since Mr. Beddard re- 
ported this beautiful worm from the tank in Regent’s Park, I have 
received specimens from Mr. Nicholson, taken in tanks from Kew 
Gardens, March, 1897. 
I have also records for certain species of Psammoryctes and 
Hyodrilus, but as they are either new to science or still under 
investigation, the localities will for the present be held in reserve. 
As to habitats, it seems almost impossible to examine the wrong 
place if water and mud are present. ‘The worms, however, have
