According to Scudder (1882, 262), and Sherborn (1902, 777), this genus was 

 proposed in 1791 by Bruguiere. Cuvier (1798a, 637-638) mentions it, but 

 does not give any species in connection with it. Lamarck (1801, 340) gives 

 only Probosddea bifida (Mueller); = Ascaris bifida Mueller [see Fabricius, 

 1780a]. Rudolphi (1801) was apparently not acquainted with the fact that 

 Probosddea had been proposed. Bosc (1802a, 43-45) attributes Probosddea 

 to Bruguiere, and mentions the following species: 



bifida (Fabricius) [= Ascaris bifida Fabricius, 1780a; = Probosddea bifida (Fabri- 

 cius) Lamarck, 1801; = Ophiostoma bifidum (Fabricius) Zeder, 1803a]. 

 rajse (Mueller, 1776) [sub Ophiostoma by Rudolphi, 1801, 48; to Fusaria and 

 Ophiostoma by Zeder, 1803a, 124, 128; eliminated from Ophiostoma as doubtful 

 by Rudolphi, 18lOa, 270]. 

 pluronectis Mueller, 1776 [renamed Echinorhynchus platessoidie Gmelin, 1790a; 



doubtful species in Rudolphi, 1809a, 310]. 

 gadi (Mueller, 1776) [= Ascaris gadi Mueller, 1776; =A. clavata Rudolphi, 



1809a, 183]. 

 rersipellis (Fabricius, 1780) [= Echinorhynchus acus, according to Rudolphi, 



1809a, 279].
