The genus according to the system of Migula is given its proper symbol which precedes the number thus:[(7)]

Bacillus coli (Esch.) Mig.becomes B.222.111102
Bacillus alcaligenes Petr.becomes B.212.333102
Pseudomonas campestris (Pam.) Sm.becomes Ps.211.333151
Bacterium suicida Mig.becomes Bact.222.232103
