DETERMINATION OF GENERIC TYPES, ETC. 105 



w. We have been unable to trace this word. Possibty it is a misprint for 

 Ethmolaimus. 



Eubostrichus Greet, 1869a, 117-11 8. Type species ? E. filiformis. 

 - Jiliformis Greet, 1869a, 117-118, pi. 7, figs. 1-4. 9 



phalacrus Greef, 1869a, 118, pi. 7, figs. 5-6. $ 

 Encamptus Dujardin, 1845a, 106-107. E. obtusus Dujardin, 1845a, 107, only species, 



hence type. 



[Not Eucamptus Chevr., 1833, coleopteron; Dej., 1833, coleopteron.] 

 Euchelidium Leuckart, 1867, 31; probably misprint for Enchelidium. 

 Euchromadora de Man, 1886, 66, 67-76. E. irulgaris (Bastian, 1865) de Man, 1886, 

 69-76, pis. 12-13, only positive species, hence type. (See also Chromadora) ; 

 also type by original designation. 



Eucoleus Dujardin, 1845a, 3, 23-25. Type species probably E. ncrophilum. 

 [Not Eucolus Muls., 1853, coleopteron.] 

 serophilum (Creplin, 1839) Dujardin, 1845a, 24. $ 9 (Description more 



complete. ) 



tennis Dujardin, 1845a, 24-25. $ 9 (Description less complete.) 

 Eucyathostomum Molin, 1861, 435, 455-463. Type species by present designation E. 



longesubulatum. 



dentatum Molin, 1861, 459-460, pi. 1, fig. 7. $ 9 

 longesubulatum Molin, 1861, 460-462, pi. 2, figs. 1-2. $ 9 (Type.) 

 copulatum Molin, 1861, 462-463. $ 9 



Molin examined all three forms, and figured the first and second. He defi- 

 nitely states that his anatomical description is based upon E. longesubulatum, 

 from Cervus campestris and C. rufus, on which account we designate this 

 species as type. The designation of E. dentatum as type would be more 

 likely to lead to confusion. 

 euryoptera Rudolphi, 1819a, 26-27, 248-249. Including Ascaris collurhnis Froelich. 



[1811: Acuaria.'} 1819: Spiroptera. 

 Eurystoma Marion, 1870, 19-21. Type species E. spectabile. 



[Not Eurystoma Rafinesque, 1818, mollusk; not Eurystoma Alb., 1850, mollusk; 

 not Eurystoma Koell., 1853, coleopteron; not Eurysoma Gistl., 1829, coleop- 

 teron; not Eurysoma Koch, 1840, arachnoid; not Eurysomus Young, 1866, 

 fish.] 



spectabile Marion, 1870, 20-21, pi. E, figs. 1-lb. $ 9 (Type.) 

 tenue Marion, 1870, 21, pi. E, figs. 2-2b. $ 



As the generic name Eurystoma Marion falls under the rule of homonyms, it 

 is immaterial which species is designated as type, except as such designa- 

 tion may possibly affect later established nontypical genera; we here desig- 

 nate spectabile because both sexes were described, and on account of page 

 precedence. 

 Eustrongylus Diesing, 1851a, 82, 325-328. Includes Dioctophyme, 1802; hence type 



species Eustrongylus gigas = Dioctophyme renale. 

 exiyua. Greldi, ? "1887"; 1889a, 28. Feb., 266; 1892a, 68.

 1845: Liniscus (type). 

 exilis Marion; 1870, 11-12, pi. A, fig. 1. 



1870: Lasiomitus (type). 

 falconis Gmelin, 1790a, 3040. See under Filaria. 



1790: Filaria (type). 

 farionis Fischer, 1798a, 304-309, fig. 7; 1798b, 98; 1799a, 95-100, pi. 2, figs. 1-6. 



1798: Cystidicola (type). [1801: Ophiostoma (type).] [1801: Pissula (type).] 

 1845: Dispharagus.
