of it, all agreeing in their peculiar characters, and he proposed for 
it the varietal name of L. mucronata. The Lagena with a collar 
at the base of the neck, described by him in a previous paper, was 
undoubtedly distinct from any of the named forms, and he pro- 
posed to call it Lagena antigua. In his examinations of the Dogs 
Bay sand one specimen only of Lagena vulgaris typica (William- 
son) had occurred, though Z. clavata was comparatively common. 
Perhaps the most interesting kind was a perfect and characteristic 
specimen of Lagena crenata, a form lately described and figured 
by Parker and Jones, from Australia, but he believed not hitherto 
observed as British in the recent state. The very magnificent 
specimens of ntosolenia mels also deserved notice; and the 
curious specimens of Truncatulina lobata, with the later chambers 
“yun wide,” and various monstrous forms of Miliolina, would be 
examined with interest.

Microscopical Soirée, June 18th, 1865. 
AGREEABLY to a resolution passed at the last monthly evening 
meeting, the Museum and Library of the Society were this even- 
ing thrown open for a Microscopical Exhibition; and as each 
Fellow had the privilege of introducing two ladies, the rooms 
were soon thronged with visitors. 
Seventeen microscopes were arranged on tables, and to each 
instrument a card was attached, containing the name of the exhi- 
bitor, with a list of the objects for examination. The instruments 
were by Ross, Pritchard, Smith and Beck, G. Oberhausen, Varley, 
Eden, &e. &e. 
Of the Fellows of the Society, Mr. F. Abbott, Mr. F. Abbott, 
jun., Dr. Agnew, Mr. M. Allport, Dr. Butler, Colonel Chesney, 
Mr. W. Johnston, Mr. F. Giblin, Mr. Napier, Mr. Roblin 
(Curator), and Dr. Turnley exhibited instruments; and Dr. 
Bright, Mr. Stone, and Mr. Legrand kindly acted as volunteers 
for the occasion. The microscope (by Smith and Beck) belonging 
to Mr. Stone attracted attention, as being the only one present 
of the binocular construction. 
With so many good instruments, and with powers ranging 
from 50 up to 1000 diameters, a great variety of objects were 
submitted for examination. Amongst others might be noticed 
the circulation of the blood in animals (tail of tadpole) ; circula- 
tion of sap in plants (Nitella) ; animal tissue; vegetable tissue ; 
method of measuring accurately microscopic objects; diatoms in 
great variety from this colony, England, and elsewhere; infu-
