1860, Crossodera (Du jardin, 1845) as genus, Cobbold, Journ. 

 Proc. Linnean Soc. London (for 1859), V, Zool., (17), pp. 31-32. 



1896, Bunodera Raïlliet, Recueil de méd. vét., (7), lïl, n° 15 

 (mardi 15), p. 160. Crossodera J)uia.rdm renamed. 



Crossodera Dujardin, 1845, has been adopted in a subgeneric 

 sensé by Stossich, Braun and Railliet ; raised to generic rank by 

 Cobbold it has been used in this sensé by Stossich (1892), Monti- 

 celli (1893) and Railliet (1896), thelatter changing the name by the 

 rule of homonyms. As the typeappears neverto hâve been selected 

 we hère designate as such the first and best known species mentioned 

 by Dujardin, namely D. nodulosum (Zeder, 1800) = Fasciola lucioper- 

 cae Mtiller, 1776. 

 Campula Cobbold, 1859. — Type, Campula oblonga Cobbold, 1859. 



1859, Campula Cobbold, Linnean Soc. Trans. London (for 1856- 

 1859), XXII, pt. III, p. 168, pi. XXXIII, figs. 84-85. Type and only 

 species Campula oblonga Cobbold, 1859. 



1895, Opisthorchis R. Blanchard, Bull. Soc. Zool. France, XX, 

 nos 8-9^ p. 217. Also : Maladies parasitaires, Bouchard's Traité de 

 path. gén., II, p. 750 (december 10). Type, Distoma felineum Rivolta, 

 1884. 



1896, « Opisthorchis R. Blanchard, 1895 » of Railliet, Recueil 

 de méd. vét., (8), III, n» 15 (marchl5), p. 160. 



Campula w^as originally proposed for distomes with a crooked 

 intestine, while Opisthorchis was based upon the topography of the 

 génital organs ; the two gênera are, however, hardly to be separated 

 at présent, since Campula agrées in topography with Opisthorchis. 



The genus as diagnosed by R. Blanchard seems to contain a 

 homogeneous assemblage of forms, and has been adopted by 

 R. Blanchard, Railliet, and Stiles & Hassall. 



Gephalogonimus Poirier, 1886. — Type, C. Lenoiri Poirier, 1886. 

 1886, Gephalogonimus Poirier, Bull. Soc. philomathique Paris, 

 (7), X (1885-1886), n^ 1, p. 22. Only and hence type species, 

 C. Lenoiri Poirier, 1886. 



This genus has been adopted by Stossich (1892, 1895), Railliet 

 (1893), and Monticelli (1893). Braun (Vermes) evidently reserves 

 jugdment upon it. It appears to us to be w^ell founded upon the 

 following diagnosis taken from the type species, and C. ovatus 

 (Rudolphi) and C. pellucidus (Linstow, 1873).
