 Ascaris phocse Fabricius, 1780a, 272. [United with Ascaris atax Mueller, 1776, 

 214, Ascaris neitsib [neitsil] Mueller, 1776, 214, and Ascaris bifida Fabricius, 

 1780a, 273; (=Proboscidea bifida (Mueller) Lamarck, 1801), by Rudolphi, 

 1809a, 119, under the name Ophiostoma dispar Rudolphi, 1809a, 119; uniden- 

 tifiable according to Krabbe, 1878.] 



Ascaris globicola (Fabricius, 1780) Gmelin, 1790a, 3036; [= Gordius globicola 

 Fabricius, 1780a; eliminated from Ophiostoma as doubtful by Rudolphi, 1810a, 

 279]. 



Ascaris rajte Mueller, 1776, 214. [To Proboscidea by Tableau encycl., pi. 32, 

 figs. 11-12; to Fusaria and Ophiostoma by Zeder, 1803a, 124, 128; eliminated 

 from Ophiostoma as doubtful by Rudolphi, 1810a, 270.] 

 Ascaris bifida Mueller, 1780, 273. [United with Ascaris phocse by Rudolphi, 



1809a, 119.]

by Rudolphi, 1819a, 26-27, 245-246.] 



Ophiostoma, 1801, was a deliberate renaming of an earlier monotypical genus, 

 hence it takes the same type as the earlier genus. It is quite possible that 

 Ascaris bifida is the type of Proboscidea. See also p. 45. 

 Ophiostomum Creplin, 1839a, 283; = Ophiostoma renamed.

 Oxynema von Linstow, 1899, 19-20. 0. rectum von Linstow, 1899, 19-20, pi. 5, fig. 56,

 Oxysoma Schneider, 1866, 29, 114-116. Type species probably 0. brevicaudatum, by 



page precedence and because of host.
