von Slebold's statement leKardingr the hooks; the species setl- 

 gera accordingly would rest upon this character. Feuereisen 

 (1868, pp. 190-200) described the anatomy ot a goose tapeworm, 

 determined as T. fasciata Rud., which possessed 10 hool<s and 

 is probably identical with von Slebold's T. setigera Frolich. 

 In 1865 and 186S Krabbe (1869, pp. 289-290) examined 400 geese 

 and found. T. lanceolata present in 77 of them, and another 

 tapeworm 9 times which possessed 40 hooks on the rostellum; 

 this latter worm Krabbe determined as T. setigera. Krabbe 

 also examined speciimens from Rudolphi's collection (see Rud.. 

 1819, p. 700) collected by Brosche in Dresden, and determined 

 by Rudolphi as T. sinuosa; these worms were "undoubtedly 

 identical with" T. setigera. Lonnberg (1889, p. 8) records this 

 species for Anser segetum (new host) in Kristineberg; he also 

 includes the white-fronted goose (Anser albifrons) among the 

 hosts, but does not state his authority. Railliet (1893, p. 301) 

 placed T. setigera in his genus Drepanidotaenia. Von Linstow 

 (1892B, pp. 503-504) states that Dr. O. Schmeil found in Cy- 

 clops brevlcaudatus a globular cysticercoid ClSSn"" in diameter, 

 with a thin, long! (2.14mm) tail, 10 hooks 39 H. on the rostellum. 

 which von Linstow identifies as the young of T. setigera. No 

 infections were made. The life history as given above is, 

 Ibprefore. theoretical though probable.

Krabbe (1860, p. 290) states that he once found in the intes- 

 tine of a domesticated goose a tapeworm head with 10 hooks 

 similar in form to those of Drepanidotaenia setigera but much 

 smaller, i. e., 24 ft long. He thought that perhaps it belonged 

 to another form, but figured the hooks as "T. setigera?;" the 

 hooks, as well as the head, bore a great resemblance to Drep- 

 anidotaenia tenuirostris. He also found a few heads with 10 

 similar hooks in the domesticated duck; the hooks were 28 /^ 

 long. Kowalewski (1894, p. !)), in a paper which I am unable 

 to read because of the language, mentioned this worm as a 

 new species under the name Taenia KrahT>ei. In a second 

 paper (1895, p. 359, Taf. VIII, fig. 27), he gives a short discus- 

 sion of the worm, and figures 2 hooks. In the German resume 

 (1894, p. 279) of this: paper he simply states: "\ species from the 

 goose which was already found by Krabbe, but not described,
