Dicheilonema Diesing Continued. 



fusiforme (Molin, 1858) Diesing, 1861a, 709. 9 



bispinosum (Diesing, 1851) Diesing, 1861a, 709. $ 9 Hosts Ophis, Tham- 



nobiuSj and Boa. 



horridum (Diesing, 1851) Diesing, 1861 a, 709. $ 9 



The subsection Dicheilostomi, 1851, which was later (1861) raised to generic 

 rank, originally contained F'daria labiata, F. physalura, F. obtuso-caudata, 

 F. bilabiala, F. acuta, F. horrida, and F. bispinosa. By the principle of vir- 

 tual tautonymy bilabiata would first come into consideration as type, but 

 such a choice is contraindicated by the lack of details given for this worm 

 in both 1851 and 1861. The history of the genus strongly indicates F. labi- 

 ata as type, unless there are other reasons why this should not be taken. 

 F. labiata was the best-known species in 1851. 

 Dicheilostomi Diesing, 1851a, 264, 276-278. Subsection of Cheilostomi of Filaria. 



See Dicheilonema. 

 Dicyema Kcelliker, 1849d, 59-66. D. paradoxum. Koelliker, 1849d, 59-66, pi. 5, figs. 



1-12, only species, hence type. 

 diesingii Molin, 1858, 151-152. 



1858: Cosmocephalus (type). 

 Dikentrocephalus Wedl, 1855, 384-385, 394. D. crinalis Wedl, 1855, 384-385, 394, pi. 



3, figs. 18-20, only species, hence type. 



1861: Dicentrocephalus Diesing, 1861a, 727; for Dikentrocephalus. 

 dimidiatus Diesing, 1851a, 298. 



1851: Deletrocephalus (type). 



Dioctophryme Scudder, 1882, 99. Misprint for Dioctophyme. 

 Dioctophyme Collet-Meygret, 1802a,. 458-464, figs. 1-4. D. renale (Gceze, 1782) Stiles, 



1901, only species, hence type. 



1851: Eustrongylus Diesing, 1851a. Type Dioctophyme renale. 

 1884: Dioctophryme Scudder, 1884, 99. For Dioctophyme. 

 Collet-Meygret used only the generic name. 

 Dipe.Uis Cobb, 1891c, Dec. 22, 155-158. Type D. typicus Cobb, 1891c. Renamed 



Diplopeltis Cobb, 1905. 

 [Not Dipeltis Packard, 1885, crustacean.] 

 minor Cobb, 1891c, 156. 

 cirrhatus (Eberth, 1863) Cobb, 1891c, 156-157. Type of Discophora, 1875 [not 



1836]. 



typicus Cobb, 1891c, 157-158, figs. 9, i-iv. 



In this genus Cobb has indicated the type by the specific name typicus, and 

 this indication should stand despite the fact that Dipeltis includes the type 

 (cirrhatus} of an earlier genus (Discophora). See p. 30. A personal letter 

 from Cobb, dated March 28, 1904, shows us that it was Cobb's original 

 intention to use typicus as type. 

 dipetala Molin, 1858, 373. 



1858: Filaria. [1861: Dipetalonema.'] 



Dipetalonema Diesing, 1861a, 620, 703-704. Type probably Filaria caudispina. 

 caudispina (Molin, 1858) Diesing, 1861a, 703-704. $ 9 

 inflexum Diesing, 1861a, 704. $ Filaria dipetala Molin, 1858, renamed. 

 mucronatum (Molin, 1858) Diesing, 1861a, 704. $ 



Probably caudispina should be taken as type, as it is the only species figured 

 and of which both sexes were known; further, the material was abundant, 

 See also 40. 



Diphtherophora de Man, 1880, 62-63. D. communis de Man, 1880, 63, only species, 

 hence type.
