296 T. B. ROSSETER ON HYMEXOLEPIS FARCIMIXALIS. 



Itudolphi, in his Entozoorum and Synopsis Entozoo., 262, p. 153, 

 and Synopsis, p. 160 (1819), agrees with Batsch, but gives us 

 no further particulars beyond dissenting from Frolich (J. A.), 

 Beschreibungen einiger neicen Eingeweidewilrmer, Halle, 1789 and 

 1802, in supposing that T. farclminalis and T. infimdibidiformis 

 were one and the same worm. 



Dujardin's description of this tape-worm in Hist, des Helminths 

 Cestoides, No. 90, p. 599 (1845), is very brief; evidently his 

 acquaintance with it was a literal one, as he merely quotes 

 Ooeze and follows Batsch in his nomenclature. 



Krabbe, Bidrag til Kundskab, No. 88, p. 321 (73), tab. 9, 

 figs. 230-232 (1869), gathered together and unravelled the 

 tangled threads of the various authors, other than those 

 mentioned above, such as Creplin (Berlin, 1851) ; Kuchenmeister, 

 Ueber Cestoden, Zittau, 1853; von Siebold, Ueber die Band und 

 Blasenwiirmer, Leipzig, 1854. He also stated that Friis, in 

 October, 1867, took a specimen of the worm under consideration 

 from the Jackdaw, and corroborated the fact that the specimens 

 which the above writers had respectively found were undoubtedly 

 the same as Goeze's T. farciminalis, although von Siebold thought 

 his specimen was Schrank's T. serpentidus, which mistake Krabbe 

 corrected. Krabbe gives us in his text, however, but little fresh 

 description of the anatomy of this worm. He figures the hooks, 

 and gives the number, from the rostellum of Creplin's, von 

 Siebold's, and Kuchenmeister's specimens to illustrate the varia- 

 bility of their formation and contour of the roots. He also 

 figures the egg with its two apparent envelopes and embryonic 

 hooks, stating their length, from Kuchenmeister's mature specimen. 

 Beyond this, however, he is silent. The following is his descrip- 

 tion : " Longit., 120 mm. ; latit., 1 mm. ; uncinulorum 10 corona 

 simplex, quorum longit. 0'020-0'023 mm. ; aperturae genitalium 

 secundae ; hamuli embryonalis, longit., 0*016-0*024 mm." 



Blanchard (Dr. Raphael), Hist. Zoo. et Jfed. des Teniades die 

 genre HymenoUpis Weinland, p. 69, 1891, in his description of the 

 genus Hymenolepis ( Weinland), refers to Weinland's suggestion 

 not only to reunite in the genus Hymenolepis, " Les teniades des 

 mammiferes mais encore un certain nombre de teniades des
