While it is to be regretted that the present anatoroical knowledge 
does not permit a more complete diagnosis, the characters given above 
furnish us a certain amount of valuable information in regard to the 
necessity of excluding from the typical Filaria certain other worms, 
usually classilied as members of this genus. 
A large number of different species of Filaria have been described. 
Of these, the following species have been taken as Wpes of distinct 
genera: 
seihiopica Valenciennes, 1856, see medinensis. 
anthuris Rudolphi, 1809a {Acuaria Bremser,- 1811; AntJnms Rudolphi, 1819; Spi- 
roptera Rudolphi, 1819; Dispharagus Dujardin, 1845). 
bourgii see loa. 
caudispina Molin, 1858 (probably type of Dipetcdonema 1861). 
conjonctivalis Penel, 1905, see loa. 
cystica Salisbury, 1868, see Oxyuris (Oxyurias) vermicularis. 
diuma see loa. 
dracunculus see medinensis. 
hominis Diesing, 1851a (equals lyinpliaiica renamed, type of Hamularia). 
hominis bronchialis see hominis. 
irritans Rivolta, 1884 {Dermofilaria Rivolta, 1884). 
labiata Creplin, 1825a (? type of Dicheilonema 1861). 
loo. Cobbold, 1864 {Loa Stiles, 1905). 
lymphatica Treutler, 1793 {Hamularia Treutler, 1793). 
medinensis Linnaeus, 1758a {Dracunculus 1759). 
inegalocliila Diesing, 1851a {Schizocheilonerna and Tricheilonerna Diesing, 1861a). 
muscse Carter, 1861d {Habronema 1861). 
rnustelarum (pulmonalis) Rudolphi, 1819a {Filaroides Beneden, 1858a). 
oculi Gervais & van Beneden, 1859b, see loa. 
physalura Bremser, 1851 (? type of Monopetalonema 1861). 
quadrilabiata Molin, 1861 ( Tetracheilonema 1861) . 
rigida Siebold, 1836 {Bradynema zur Strassen, 1892). 
subconjunctivalis Guyon, 1865a, see loa. 
In connection with the genus Filaria^ and to some extent in addi- 
tion to the genera just mentioned, certain other groups come into 
consideration. Reference is made to the genera which Diesing, 
1861 a, ^ included in his family Sjnruridea^ namely, the following sub- 
families : 
1. Acheilospiruridea, with the genera Spiroptera, Eucamptus, Proleptus,Hisiioceplialus, 
Dispharagus, Spiropterina; and 
2. Cheilospiruridea, with the genera Spirura, Hystrichis, Echinocephalus, Cheilos- 
pirura, and PhysocejAialus. 
In reference to Sj>iropte)Xi^ it mn}" be noticed that the following 
species have been made types of genera: 
anthuris Rudolphi, 1819a {Acuaria Bremser, 1811; Anthuris Rudolphi, 1819; 
Spiroptera Rudolphi, 1819; Dispharagus Dujardin, 1845). 
hamulosa Dieting, 1851a {Cheilospirura DieAng, 1861). 
^ This paper was presented to the Academy on December 6, 1860, but does not 
appear to have been published until 1861. It is erroneously given as December 6, 
1861, in Stiles & Hassalhs Index Catalogue of Medical and Veterinary Zoology.
