variam aeque ac denfiffimam determinari nequit, 
tayien paima longiora effe videntur. 
Obferv. III. A Conferua fugacijjima , cui teneritate fua 
fimilisefl, differt, i. Filis varie inflexis, in 
ficco flatu grifeis et chartae vel vitro arctiffime 
adglutinatis. 2. Geniculis linearibus, parum con¬ 
tractis, fubpellueidis: nec articulis aequalibus 
magnitudine et figura. 
Filamentis geniculatis rnmojis. 
Conferua crifpata filamentis geniculatis, dichoto- 
inis, capillaribus, denfiffime inflexis: geniculis tenuifiimis; 
articulis oblongis, linea fpirali pulcherrime pictis, ficcitate 
alternatim compreffis. 
In aquis dulcibus, ftagnantibus aefiate ad fuperficiem, 
magnos, faepe vitra pedales, denfiffunos, bullas non raro 
aereas includentes, extractione ex aqua tenaces et cohaeren¬

Filamenta longa, capillaria, tenuia, primo intuitu ex¬ 
acte aequalia, debi.ia, tamen fat tenacia, varie et denfiffi- 
me inter fe inflexa, vt abfque ruptura feparaii nequeant. 
Rami alterni, remotiflimi, filamentis craflitie aequales. 
Genicula in viuido flatu microfcopii compofiti ope rite obfer- 
vanda, tenuiffima, pellucida, annularia; ficcitate euiden- 
tia et obfcura. Articuli in vigore fub microfcopio folari ob¬ 
longi, maxime pellucidi, linea obfcura fpiraliter circumuo-

natim compreili, fubdiaphani. 
Obferv. I. Aefiate, vbi laetiflimum virorem habet et ad 
aquae fuperficiem in confpcctum venit, filamen¬
