 Spironoura Leidy, 1856, Feb., 52-53. Type species ? S. gracile. 



J861: Spirura Diesing, 1861, for Spironoura Leidy, not Spirura E. Blanchard, 



1849. 



gracile Leidy, 1856, 52-53. $ 9 

 affine Leidy, 1856, 53. $ 9 



Spiroptera Rudolphi, 1819a, 22-29, 235-255. Acuaria and Anlhuris renamed, hence 

 same type, Spiroptera anthuris. For discussion of this very complicated 

 case, see p. 48. 

 Spiropterina van Beneden, "1858a, 270;" 1861a, 270-271. S. coronata, only species, 



hence type. 



Spiropteru Rudolphi, 1819a, 237. Misprint for Spiroptera.

Spiroxis Schneider, 1866, 29. Corrected to Spiroxys Schneider, 1866, 125. 

 Spiroxys Schneider, 1866, 125-126. S.. contorta (Rudolphi, 1819) Schneider, 1866, 125; 

 =Spiroptera contorta Rudolphi, 1819a, 25, 242-243, only species, hence type. 

 1866: Spiroxis Schneider, 1866, 29. Corrected to Spiroxys. 

 Spirura E. Blanchard, 1849a, 161-165. Type species probably S. talptv. 

 [Not Spirura Diesing, 1861a.] 

 talpx (Gmelin, 1790a) E. Blanchard, 1849a, 162-164. $ 9 Host Talpa 



europxa. See also Spiroptera stmmosa. To Filaria by Schneider, 1866. 

 megastoma (Rudolphi, 1819) E. Blanchard, 1849a, 164-165. $ 9 Host 



Equus caballus. To Filaria by Schneider, 1866. 



Under ordinary circumstances it would be better to select megastoma as type, 



on account of its host, but Blanchard seems to have based his genus more 



upon talpsc than upon megastoma; on this account, his original intentions 



will probably be better carried out by taking (alp;c as type. 



Spirura Diesing, 1861a, Dec. 6, 681-682. Spironoura Leidy, 1856, renamed, hence 



takes same species as type. 

 gracilis (Leidy, 1856) Diesing, 1861a, 681-682. 

 nffinis (Leidy, 1856) Diesing, 1861a, 682.
