developed oblique muscular bands which separate the longitudinal 
coat in the median line inferiorly. 
The occurrence of an Annelid proper devoid of bristles is an 
interesting fact ; for, though such organs are feebly developed in 
Tomopteris , they have been considered on the whole so universal, 
that, for example, the two great divisions Polychseta and Oligo- 
cheeta rest thereon. The new form likewise shows no trace 
of segmentation externally, in this respect agreeing with the 
Nemerteans, yet in structure it is truly an Annelid proper. It is 
difficult to assign its exact position at present, and the association 
with the Opheliidm may be regarded as provisional. 
4. The following concluding Kemarks were made by Mr 
D. Milne Home, who occupied the Chair in room of the 
President : — 
I. I have been requested by our Secretary to announce formally 
from the Council, that this is the last meeting for the Winter 
Session. 
You will have seen from the billet, that our President, Sir 
William Thomson, was to have been in the chair to-night, and 
to have closed the session with some remarks suitable to the occa- 
sion. 
The Council are much disappointed, and no doubt you also are; 
but I am more distressed than any one at Sir William Thomson’s 
absence. There is a letter from him to the Secretary, dated on 
Friday last, mentioning that he could not attend this evening, as 
he expected to be in his yacht to-day in the Bay of Biscay. 
The Council, therefore, had no alternative but to appoint me, as 
the only Vice-President at hand, to occupy the chair to-night. The 
occupation of the chair is unaccompanied by any difficulty,— but the 
other duty, of offering concluding remarks worthy of your accept- 
ance, I find it simply impossible to perform. I am sure you will 
neither expect it, nor wish me to attempt it. 
Such remarks, therefore, as I shall offer, will be matter of mere 
form, and will not contain thoughts or suggestions, or information 
of any scientific value.
