NEW YORKSHIRE EARTHWORMS.

A vEar’s work among the earthworms of Yorkshire has enabled me 
to correct and enlarge the list which I published some months ago. 
As it seems likely that the list will be still further enlarged by 
continuous research, I do not propose at present to revise it, but 
simply place on record new facts. I have recently been able to 
identify a new worm found in the Haigh Beck, Idle, which has 
I believe, been regarded formerly as the young of another species. 
In 1836 there appeared a catalogue of species of Annulose 
Animals in Loudon’s Magazine of Natural History (vol. ix., 235)s 
by Templeton, in which we find reference to an unknown worm. 
This is named Lumbricus omilurus (= Omilurus rubescens Temp.). 
Recent writers have all pushed it aside, and relegated it to the limbo 
of the unknown. I have been able to recover what I believe to be 
Templeton’s species, and as it is a genuine Lumbricus, and at present 
is without synonyms, I purpose retaining the name Zumbricus 
rubescens (Temp.), and calling it the Ruddy Worm, as distinguished 
from the Red Worm (Luméricus rubellus Hofim.), with which 
I believe it has been confounded. 
The following is a description of my Yorkshire specimens, which 
corresponds very nearly with that given by Templeton. 
Colour exactly like the Red Worm, except the tail, which is 
usually a more transparent flesh-colour ; beautifully iridescent, pale 
underneath. About three or four inches long, fore part of the body 
round, tail flattened. No apparent girdle (clitellum), but a well- 
defined region (segments 34 to 39), modified especially on the 
underside to serve the purposes of a clitellum. A band connects 
segments 35 to 38 on the under surface—this is known as ‘ubercula 
pubertatis, and is farther back than in any other known British 
species of Lumbricus. In the Red Worm (Z. rudedlus), the well- 
marked clitellum extends from segments 27 to 32, the tubercula from 
28 to 31. Total number of segments about 120. Sete of three kinds, 
arranged as in typical Lumbricus, with specially modified (penial) setae 
on segments 11, 13, 34 to 40 (under the clitellum). The first dorsal 
pore varies in position between the sth and the 7th segments. The 
male pore is on a papilla in segment 15, and prominent papillze are 
found in the 28th and 2oth quite ventrally. The worm like the 
other true Lumbrici, and unlike the majority of the Allolobophor®, 
yields no coloured fluid, but secretes a slimy mucus when irritat
