La Periplaneta americana, habitée par un nombre encore plus 
considérable de parasites végétaux et animaux, devient a ce 
point de vue encore plus digne d’étre étudiée. . . . Le pauvre 
béte est une vraie ménagerie ambulante.

APPENDICES 
The plants and animals are listed by phylum, class, order, and 
family in the order adopted by the taxonomic sources we have fol- 
lowed, but in alphabetical order by genus and species. In listing the 
authors of the species, we have followed the current usage of spe- 
cialists in the field; for the helminths the original describer, the re- 
viser, and the dates of both are given; for the bacteria and fungi the 
describer and reviser are listed; for the protozoa the original de- 
scriber is given. 
Each organism, in so far as we have been able to determine, is 
listed by its current name. To reduce the number of entries for each 
organism, we have synonymized the names reported by earlier authors 
with the names now in use. The only synonymy given is that which 
identifies the organism by the name used by the author of the paper 
cited; no attempt was made to prepare complete taxonomic synony- 
mies. 
Under the name of each organism the associated cockroaches are 
listed as being natural or experimental vectors. The name of each 
cockroach is followed by the country in which the observation was 
made, the authority, and comments on the invasion. Unidentified 
cockroaches associated with specific records are indicated by the 
word “Cockroaches.” Question marks following the names of or- 
ganisms or countries indicate tentative or questionable identifications.
