Filaraia Rudolphi, 1809a, 69. Misprint for Filaria. 

 Filaria Mueller, 1787, 64-67. Type species by elimination F. martis. 



In the original reference Mueller (1787) does not give any specific names in 

 connection with this genus, but he gives a number of bibliographic refer- 

 ences arranged under their respective hosts. The species in question, so far 

 as they can be determined by a comparison of Mueller, 1787, and Gnielin, 

 1790a, are as follows: 



A. In Mammals: 



leonis Gmelin, 1790a, 3040. [Sp. inq., in Rudolphi, 1809a, 68; Diesing, 



1851a, 280; Molin, 1858, 421; Stossich, 1897, 71.] 

 Zeporis. Gmelin, 1790a, 3040. [Sp. inq., in Rudolphi, 1809a, 69; Diesing, 



1851a, 280; Molin, 1858, 421; Stossich, 1897, 72.] 

 martis Gmelin, 1790a, 3040. [Renamed "Filaraia" mustelarum Rudolphi, 



1809a, 69; Filaria mustelarum subcutanea Rudolphi, 1819a, 7, 216; F. 



quadrispina Diesing, 1851a, 271-272; see also F. perforans, Molin, 1858, 



387; see also Stossich, 1897, 32.] 



B. In Birds: 



gallime Gmelin, 1790a, 3040. [See Capillaria semiteres Zeder, 1803a, 61; 



Hamularia nodulosa Rudolphi, 1809a, 84; Trichosoma longicolle 



Rudolphi, 1819a, 14, 221.] 

 falconw Gmelin, 1790a, 3040. [Renamed Filaria falconum Rudolphi, 



1809a, 70, sp. dub.; see also F. foveolata Molin, 1858, 375; see also 



F. nodispina Molin, 1858, 402.] 

 ciconise Gmelin, 1790a, 3040. [See Dicheilonema labiatum.'} 



C. In Insects: [Probably all Gordiidse or Mermithidse.] 



scarabfd Gmelin, 1790a, 3040. 



carabi Gmelin, 1790a, 3040. 



silphse Gmelin, 1790a, 3040. 



grylli Gmelin, 1790a, 3040. 



monoculi Gmelin, 1790a, 3041. 



lepidopterorum Gmelin, 1790a, 3041. 



tenlhredinis Gmelin, 1790a, 3041. 



phryganess Gmelin, 1790a, 3041. 



Lamarck (1801, 340) mentions only 1 species, namely, Filaria equi Mueller, 

 but this can not be taken as designation of type, since Mueller did not 

 include it in his original (1787) species. Since Mueller distinctly intended 

 to separate Filaria from Gordias, and since all the forms he mentions for 

 insects probably belong to the Gordiidse or Mermithidse, and some of them 

 have already been eliminated from Filaria, it will be best not to consider 

 the insect parasites in determining the type of Filaria; such a procedure of 

 exclusion is further justified by the tendency since Mueller's time to.look 

 upon Filaria as a genus parasitic in warm-blooded animals; it also agrees 

 w^ith the principle of page precedence. 



In considering the 6 remaining species (3 from mammals and 3 from birds), 

 it may be noted that F. gallinse and F. ciconise have already been elimi- 

 nated; further, F. leonis and F. leporis are viewed as doubtful species, hence 

 these may next be eliminated from consideration. There now remain 

 F. martis and F.falconis. Of these two, conditions clearly favor the selection 

 of F. martis (see F. quadrispina Diesing) .
