In order to make the text more useful to scientific workers, various 
abbreviations are used and an effort is made to designate the status 
of some of the names by use of type, as follows: 
CAPS are used for systematic names above the superfamilies. 
SMALL CAPS are used for valid, available, and in some cases for dead super- 
famil}^ names (ending in oidea), family names (ending idae), and subfamily 
names (ending inae). 
Larger heavy face type, is used for side headings for current generic and 
specific names of hosts; slightly smaller heavy face type is used for side headings 
for current generic names of parasites. 
Italics are used for — 
(1) Generic names which have a definitely valid, or an available status for 
the species quoted in connection with said generic name, or are 
considered sub judice; i. e., they are not definitely known to be dead. 
(2) Specific names which have a definitely valid, or at least an available 
status for the animal in question, or are sub judice; i. e., they are 
not definitely known to be dead. 
Roman type, lower case, is used for — 
(1) Generic names w^hich have a definitely unavailable (hence dead) status 
(as homonyms, or because of advances in classification) in con- 
nection with the species quoted with said generic name, especially 
under the host cited. 
(2) Specific names which are definitely unavailable (hence dead) for the 
species in question, especially as applied to the reported occurrence 
in the host cited. 
In order to simplify the lists of technical names, the synonyms — 
when a considerable number are more or less generally recognized — 
are placed in footnotes; if the synonyms are only few in number they 
are cited in the text in order to save expense in printing. 
For special information, in connection mth some of the names, 
the following signs and abbreviations are used — hut their absence from 
any given entry has no significance. 
t In this and the companion key-catalogs to the parasites of animals other 
than man, the dagger (f) is used before superspecific names to signify that 
characters, diagnoses, or other data regarding these superspecific groups are to 
be found in the key-catalogs of the parasites of man; when used before a specific 
name it signifies that the species in question has been reported for man. Thus 
the key-catalogs to the protozoa, the worms, and the arthropods of Homo are 
taken as bases for all the companion numbers. Groups not reported under 
Homo are taken as bases for all the companion numbers. Groups not reported 
under Homo are keyed under the order in which is classified the first host for 
which the parasites are cited in these ke5^s. Thus ail parasites in this bulletin 
are classified under # 407 CARNIVORA, p. 922. 
* This species has been reported for this host for the United States. 
# This sign refers only to the hosts, and these have serial numbers which are 
independent of the serial numbers of the parasites. 
? Doubts have been expressed or exist as to the name or to the specific or 
the generic determination. 
[ ] The use of brackets around a specific entry signifies that the species has 
been classified, either as a synonym or otherwise, under the genus cited above 
but that our card catalog contains no citation of an actual binomial combination 
with the generic name in question, and the present citation is not to be construed
