82 Friend: Researches among Annelids. 
of the memoirs of Dr. Michaelsen and Ude, I have not been able 
to consult their diagnoses of this species, so that I cannot tell 
whether or not this point has been noticed in the Continental 
forms. Perhaps, when the spring arrives, some collector would 
send me more material from Apperley, to enable me to make — 
a more complete examination. 
2.—Worms NEw TO SCIENCE. : 
The pressure of work has prevented me hitherto compiling — 
and publishing a list of the new species of aquatic and micro- — 
scopic worms, upon which I have been working at intervals 
during the past two or three years. There are two, however, 
which are of such interest that I give a brief preliminary account 
of them, in order to stimulate research. 
(1) Limnodrilus wordsworthianus Friend. This species 
was found by me at Old Carlisle, near Wigton, Cumberland. 
It has all the characteristics of a Lémnodrilus, and comes very 
near to L. hoffmeisteri Clap. It is found in mud at the roots of 
water Plants, and looks like a Tubzfex or Stylodrilus. When 
it is at once distinguished by the absence of capilliform sete, while 
it lacks the characteristic penis of Stylodrilus, and has more than. 
two sete in the bundles of the anterior segments. It is two to three 
inches in length, but owing to its habit of coiling up when under 
observation, it is very difficult to obtain exact measurements 
without killing the specimens. The blood-tufts in the epidermis 
are fully developed. The head is pointed, the prostomium being — 
portion of the y. The chitinous penis-sheaths are trumpet- 
shaped, and about four times as long as broad. The brain is 
rounded off behind, a kind of squared circle; but in the living” 
worm the appearance changes with every convolution, The. 
nephridia in the front part of the body are covered with vesicular 
cells. Delicate papilla cover the prostomium, and extend to 
the peristomium. This, I believe, is a feature not recorded for 
other species. 
2) Marionia appendiculata Friend. A worm of peculiar 
interest found in backwash at Askham, near Furness. Its most 
striking peculiarity, and one which is, so far as I am aware, 
unique in this group of annelids, is the presence of a pair of 
Lianne ciliated Wetec ss connected with and fo orming the
