256 BULLETIN 140, UNITED STATES NATIONAL MUSEUM 



Railliet, Henry, and Sisoff, 1912; Hainannia longeomata (Molin, 

 1860) Stiles and Hassall, 1920. 



Hosts. — Primary: Ciconia maguari; secondary: Unknown. 



L ocation. — Proventriculus. 



Morphology. — Echinuria (p. 244) : Mouth with 2 small inconspicu- 

 ous lips. Cordons very long, briefly recurrent (brwi regredientes) , 

 according to Molin: Gendre (1919) says this may be a retraction due 

 to fixation, a thing he has seen in E. leptoptili; if the cordons were 

 truly recurrent the species would belong in Synhimantus ; the cor- 

 dons anastomose in pairs. Cuticula with thick transverse striations. 



Male unknown. 



Female 8 mm. long by 200/* wide. Anus near caudal apex. Vulva 

 small, anterior to anus. 



Life history. — Unknown ; probably involves intermediate stages in 

 other hosts; (see E. uncinata, p. 246). 



Distribution. — South America (Brazil). 



ECHINURIA LONGEVAGINATA (Molin, 1860) Cram, 1927 



Synonyms. — Dispharagus longevaginatus Molin, 1860c; Spirop- 

 tera ciconiae-maguari' 1 Molin, 1860; Acuaria longevaginata (Molin, 

 1860) Railliet, Henry, and Sisoff, 1912; Synhimantus longevaginata 

 (Molin, 1860) Skrjabin, 1924. 



Hosts. — Primary : Ciconia maguari; secondary : Unknown. 



Location. — Esophagus. 



Morphology. — Echinuria (p. 244) : Mouth with 2 projecting tri- 

 angular, lateral lips (fig. 319a.). Cuticula transversely striated. 

 Anterior extremity markedly attenuated. Cordons long and 

 straight, anastomosing. According to Molin, the cordons are briefly 

 recurrent here as in E. longeomata; they are regarded in this case, 

 as in that, as not recurrent for the reasons given in discussing that 

 species. 



Male 6 mm. long by 100/* wide. Posterior extremity twisted spir- 

 ally, excavated ventrally, and with acute apex. Caudal alae (fig. 

 319 b) long and wide, with thick edges. Four pairs of preanal and 

 5 pairs of postanal papillae, very small. Right spicule short and 

 thick; left spicule six times as long as right, slender and alate. 



Female 7 to 8 mm. long by 200/i wide. Tail conical, with blunt 

 tip. Anus near end of tail. Vulva anterior to anus. 



Life history. — Unknown; probably involves intermediate stages 

 in other hosts, (see E. uncinata, p. 246). 



Distribution.. — South America (Brazil).
