PART II. LIST OF GENERIC NAMES, CHIEFLY NEMATODES, WITH 

 THEIR ORIGINAL AND TYPE SPECIES. 



The following list includes all of the nematode genera (both free- 

 living and parasitic) which we have been able to find recorded. It also 

 includes all of the species which come into consideration in determin- 

 ing the type species of the genera in question. With a few exceptions 

 (in cases of type by original designation) all of the original species are 

 given under each genus, and under these species cross references are 

 given to the various genera in which they have been placed. 



For various reasons it has not been found feasible to confine the list 

 entirely to the nematodes; accordingly, occasional references will be 

 found to genera of other groups. 



abbreiiata Rudolphi, 1819a, 30, 257-258. 



1819: Physaloptem. 



abbreviates Rudolphi, 1819a, 21, 234-235. 

 1819: Cucullanus. 1845: Dacnitis. 

 abbreviates Villot, 1874, Jan., 57. 



1874: Gordius. 1897: Parachordodes. 

 Acanthocephala Rudolphi, 1808a, 198. Ordinal name. 

 Acanthocephali Burmeister, 1837a, 527. Family name. 

 Acanthocephalos Goeze, 1782a, 141; for Acanthocephalus. 



Acanthocephalus Koelreuter 1771a, 499-500, 503, pi. 26, figs. 5, a-d. Type Echmo- 

 ' rhynchus anguillse Mueller, designated by Luehe, 1905, 329. 

 [Not Acanthocephalus Lap., 1833, hemipteron.] 



Koelreuter gives no specific name, but the parasite in question is clearly a 

 thornheaded worm reported for Cyprinus rutilus, adhering to the intestinal 

 wall. See also Echinorhynchus lavareti Rudolphi, 1809a, 313. 

 Acanthocheilonema Cobbold, 1870b, 9-14. A. dracunculoides Cobbold, 1870b, 10-14, 



only species, hence type. 

 Acanthocheilus Molin, 1858, 154-155. A. quadridentatus Molin, 1858, 155, only species, 



hence type. 

 [Not Acanlhocheila Stal, 1860, hemipteron; Acanthochila Stal, 1873, for Acan- 



thocheila.'] 



Acanthopharynx Marion, 1870, 34-37. Type species probably A. affinis. 

 perarmata Marion, 1870, 34-35, pi. K [26], figs. 1-lf. 9 

 oculata Marion, 1870, 35, pi. K [26], figs. 2-2c. 9 

 striatipunctata Marion, 1870, 35-36, pi. K [26], figs. 3-3c. 9 

 affinis Marion, 1870, 36, pi. K [26], figs. 4-4b. $ 9 



There seems to be no evidence that males were examined for the first three 

 species.
