ARCHER—ON RHIZOPODA. 293 
those I have (be it but provisionally as it may) referred to Pleurophrys ; 
the pseudopodia are, however, far more changeable, and more arbo- 
rescent, and the foreign bodies on the “‘ test’”’ far more loosely aggregated 
than in Pleurophrys or any Difflugia. The forms meant to be repre- 
sented by fig. 1 and fig. 6 are, perhaps, the only two that could be passed 
over the one for the other; but I need hardly insist on their differences 
being sufficiently important. The whole of the forms which are pour- 
trayed in my figs. 1, 2, 3, 4, 5, and 6, seem all to belong to a type quite 
and equally distinct from Difflugia as from the Gromida. 
Genus, Gromia (Duj.). 
Gromia socials (Arch.). 
Pl. X., figs. 7-11. 
Specific Characters.—Very minute, often occurring socially, body 
bluish, granular, with a distinct sharply marked, white nucleus, contain- 
ing a minute dark nucleolus; pseudopodia elongate, branched, slender, 
reticulosely incorporated with each other, often mutually with those pro- 
ceeding from other indiwiduals, showing wrregularly shaped expansions, 
and carrying along in a slowish current minute opaque granules; test 
hyaline, colourless, orbicular, or broadly elliptic. 
Measurements.—Diameter about ~755” to zeo7"’ 
Locahty.—A single pool only in ‘‘ Glen-ma-lurValley,”’ hence as yet 
very rare. 
Affinities and Differences. —The minute size, hyaline test, dense 
body substance, minute passage for the pseudopodia, white nucleus 
(with its nucleolus), and social habit, clearly mark out this form from 
other Gromie ; its distinctions from Cystophrys Haeckeliana have been 
pointed out, as they seem to me, in a previous part of the present com- 
munication. 
Dr. J. Barker exhibited preparations showing mucous folds in 
Stomach of the Lioness. 
The following resolution was passed unanimously :— 
‘* That the Meeting desire to place on record the loss the Society has 
sustained by the death of their esteemed Member, John Good, Esq.” 
Mr. Witttam Arcuer laid his resignation of the office of Joint 
Honorary Secretary before the Meeting, which was ordered to be en- 
tered on the Minutes. 
Professor E. Percevan Wricut, M.D., laid his resignation of the 
office of Joint Honorary Secretary before the Meeting, which was also 
ordered to be entered on the Minutes. 
These resignations were in consequence of the resolution passed at 
the last night of meeting, vide p. 230. 
The Society then adjourned to the first Wednesday in November.
