 epizootic disease among frogs associated with edema, more particularly of the 

 extremities, aud great weakness is said to have been due to Bacillus srp- 

 ticaemiae ranarum- n. sp. "The bacillus is a slender Gram-negative rod, pos- 

 sessing one flagellum, motile, and not forming spores. It is pathogenic for 

 certain fishes, crabs, guinea pigs, rabbits, and pigeons. The organism forms a 

 toxin to which guinea pigs and rabbits are susceptible."
