Haematotrephus lanceolatum ( Wedl, 1858 ) ; Haematotrephus consimile Nicoll, 1914 ; Haematotrephus adelphus Johnston, 1917 (= Uvitellina adelphus [ Johnston, 1917 ]); U . pseudocotylea Witenberg, 1923 ; U . magniembria Witenberg, 1923 ; U . simile ( Stossich, 1902 ) ; Cyclocoelum ( U .) dollfusi Tseng, 1930 (= U . dollfusi [ Tseng, 1930 ]); Uvitellina keri Yamaguti, 1933 ; Uvitellina tageri Yamaguti, 1933 ; U . macroisophaga Hannum & Wilson, 1934 ; Cyclocoelum obscurum ( Leidy, 1887 ) ; U . adelphus ( Johnston, 1917 ) ; Cyclocoelum titiri Chatterji, 1958 (= Haematotrephus titiri [ Chatterji, 1958 ] n. comb.); Haematotrephus ( Haematotrephus ) lobivanelli Gupta, 1958 ; Haematotrephus ( U .) kaniharensis Gupta, 1958 (= Uvitellina kaniharensis [Gupta, 1958]); and U . indica Siddiqi & Jairajpuri, 1962 — Dubois (1965) . Remarks. Originally described as Monostoma vanelli Rudolphi, 1819 , this species was redescribed by Bashkirova (1950) , who considered it to be in Uvitellina . We support the synonomies of both U . keri and U . tageri with U . vanelli as proposed by Dubois (1965) because both are virtually identical to this species. In addition to measurements, these two species are like U . vanelli by having the uterine loops overreaching the ceca laterally, the posterior-most uterine loops terminating anterior to the anterior testis and they are all from species of the same genus of charadriiform birds; U . tageri being from the same host species. No oral or ventral sucker described— Bashkirova (1950) .
