Marks , employed for classifying the Schizomycetes. 129 
(a) Cocci closely packed in firm cartilaginous-mucous 
matrix. 
Thiopoly coccus. Cocci densely grouped without 
order, in irregular compact families. Divisions 
in one plane. 
Sarcina. Cocci in regular, ckbical, closely packed 
families of eight. Divisions in three planes. 
(3) Cocci loosely aggregated in a flattened mucous matrix. 
Lampropedia, Cocci loosely grouped in fours, 
regularly distributed in a firm mucus in flat 
tables, like parallelograms. Cocci dividing in 
two planes. 
Thiocapsa. Cocci few, in irregular families, in a 
firm flat mucous membrane, without definite 
outlines, loosely associated without order. 
Divisions in three planes. 
Pediococcus. Cocci in fours, the small regular 
families loosely connected in one stratum, 
enveloped by an amorphous, thin, hardly con- 
spicuous deliquescent mucus. Divisions in two 
planes. 
C. Streptococcaeeae. 
Cocci in moniliform chains. Arthrospores, larger than the 
mother-cells, developed in or at end of chains. 
(a) Filaments (chains) in membranous gelatinous capsules. 
Leuconostoc. Capsule large, dense, lamellose. 
Schuetzia. Capsules compressed, thin, not lamel- 
lated. 
(3) Filaments (chains) in cylindrical sheaths. 
Perroncitoa. Sheath membrano-gelatinous. 
(y) Filaments (chains) devoid of capsule or sheath. 
Babesia, Filaments falsely dichotomous, with 
arthrospores at apex. 
Streptococcus. Filaments simple, with scattered 
arthrospores. 
D. Mieroeoeceae. 
Cocci devoid of either cysts, capsules, or definite sheaths of
