Hymenolepis (Taenia) farciminalis, Bosseter, 1908. 



This tape-worm has bad in its nomenclature a very chequered 

 experience, having been respectively named Taenia farciminalis, 

 T. serpentulus, T. angulata, and T. undidata. It has been found 

 parasitic in the alimentary tract of the crow, starling, jay, and 

 jackdaw. 



Goeze (jYaturrjeschichte, 1782, p. 397, pi. 31b, figs. 19-21) was 

 the first to find, describe, and delineate this tape- worm, and from 

 the peculiar formation of the terminative or ripe segments of his 

 specimen he named it Taenia farciminosa, or the sausage-shaped 

 tape- worm — " Der Wurstgliedrichte Bandwurm." He took it from 

 the intestine of the starling (Sturnus vulgaris), and his specimen 

 was " Fiinf Zoll," or 126-127 mm. in length. His drawings, exe- 

 cuted by Graff von Borste, illustrate the scolex with the evaginatecl 

 rostellum and suckers, the neck with commencing segmentation 

 and sections of the middle and terminative segments of the 

 strobila ; but nothing is figured, or mentioned in the text of the 

 internal anatomy. The following is Goeze's description : " Taenia 

 farciminosa : Articulis longiorobus farciminosis ; collo breviori 

 simplici ; capite sub quadrangulari quadriosculato ; proboscide 

 uncinulata." Unfortunately he does not substantiate the latter 

 statement (uncinulata) by giving us a drawing of the hooks, or 

 the number on the rostellum or proboscide. 



Batsch (A. J. G. C.), Naturgeschichte der Bandwarmgattung, 

 p. 198, figs. 132-133, Halle, 1786, restudied this worm and 

 altered the name to T. farciminalis.
