The Irish Naturalist, 
February, 
The problem before us has exercised Southern(5) as well 
as myself, and he hesitated whether or not to record L. 
lineatus as Irish. On looking over my notes of Irish Oligo- 
chaets collected by myself in Belfast and Dubhn in former 
years, however, I find that more than one description agrees 
entirely with that of lineatus, while the material from 
Manchester provided specimens of such diverse form that 
one could be named lineatus and another verrucosus, though 
every intermediate stage could be traced. Since Miiller's 
name takes precedence, and his species is undoubtedly to 
be recorded as Irish, we have the following results : — 
1. Lumbricillus lineatus O.F.M. Collected at Belfast by 
myself, Whitsuntide, 1896 ; Ringsend, Dublin, March, 
1913 ; Dodder, in mud, by Ballsbridge, same date. 
2. Lumbricillus verrucosus Clap. 
3. Lumbricillus subterraneus Vejd. 
4. Lumbricillus litoreus Hesse, 
all to be regarded as more or less closely related to lineatus, 
either as mere varieties or as subspecies. 
5. An undetermined worm, wrongly associated by me 
with Saenuris lineata Grube, found at Ringsend, Dublin, 
with L. lineatus, March, 1913. 
I wrote in the Zoorogist{6) : " While it is an undoubted 
Tubificid, it is the only species yet discovered in Britain 
which has setae like Lumbricillus. In this respect, therefore, 
it is a link between the red-blooded Enchytraeids and the 
Tubificids." As it is desirable to be able to refer to this 
interesting worm in future under a definite name, and as 
my attempt to co-ordinate it with Saenuris lineata Grube 
was an error, I propose the following solution of a difficult 
question. 
Genus Aegialina Friend, n. gen.^ 
Characters as defined for the family Tubificidae by the 
authorities, except that there are " absolutely no capilli- 
form setae, and no forked setae, but all of the Pachydrilid 
{Lumbricillus) type." — Zoologist, June, 1912, p. 221. 
1 The generic name is from the Greek word atytaA,os> the seashore, 
strand ; and the specific name has allusion to the sigmoid shape of the 
setae.
