Observations upon the Structure of a Genus of Oligo- 
chseta belonging to the Limicoline Section. By 
Frank E. Beddard, M.A., F.R.S.E., Prosector and Davis 
Lecturer to the Zoological Society of London .

(Abstract.) 
The present paper refers to a number of specimens of Moniligaster , 
some of which belong to the species Moniligaster Barwelli already 
briefly described by myself;* others (one other at least) are possibly 
referable to a distinct species. I do not, however, give this species 
a name, principally for the reason that it will very possibly turn 
out to be identical with one or other of the species recently noted 
by Professor A. G. Bourne from the Nilgiris and Shevaroys. I am 
not at all certain that M. Barwelli is not identical with his M. 
minutus. The present paper contains a fuller account of the repro- 
ductive organs than I have yet given, but unfortunately it will be 
still found to be incomplete in certain particulars; some of these 
gaps, e.g ., the clitellum and the egg-sacs, are filled up by Bourne’s 
paper, assuming of course that the characters of these organs as 
given by Bourne will turn out to be generic , which is likely. The 
present paper contains some account of the other organs of the body, 
which has not yet been published. 
As I have taken pains in common with other naturalists to point 
out that the Oligochteta cannot be divided into “ Limicolce ” and 
“ Terricoleef it may seem illogical to speak of a “ Limicoline 
Section.” As, however, I regard most earthworms as forming a 
distinct group marked off from other Oligochmta, it is convenient 
to have an expression for Oligochseta which agree in not being 
“ Terricolce for this purpose the terms “ Limicolae ” or “ Limicoline 
Section” are made use of simply as a matter of convenience. 
I consider (in opposition to Dr Rosa) that Moniligaster is not an 
earthworm except in habit; its affinities with earthworms are 
chiefly shown in the presence of gizzards, in the thickness of body 
* I give no references to literature in this Abstract ; they will be found in the 
complete paper.
