Gurlt 1 in 1831 obtained Budolphi's specimens and gave two figures 

 of the worm. Creplin 2 in 1842 also studied the originals and gave 

 quite a, fair description of them (for details see Stiles 3 ). 



Since Creplin's time numerous authors have mentioned T. denticulata 

 as a parasite of cattle and sheep, and quite a number of specimens 

 have been determined as belonging to this species (for details see 

 Stiles' 1 ). ^ In 1891 Blanchard 5 placed this species in his genus Moniezia. 

 Later, in 1S!)3, 1 studied several end segments of Kudolphi's originals, 

 compared them with several specimens determined as T. denticulata 

 by various helminthologists, and called attention to the disagreement 

 in the statements of different authors as well as TO the fact that none 

 of their specimens agreed with J udolphi's original type. The few 

 statements I made upon the originals were extremely meagre and 

 guarded, showing that "we know practically nothing of the micro- 

 scopic anatomy of M. denticulata." 



Upon examining originals of Baird's Tcenia f/oesei and Riehm's 

 Dipylidium latissimum, Hassall and Stiles were surprised to find the 

 great resemblance the cirrus bore to the cirrus in the few segments of 

 Bndolphi's material deposited in the United States National Museum. 

 Through the kindness of Geheimrath Mobius and Dr. A. Collin we 

 obtained further material of liudolphi's originals and were able to 

 prove 7 that Tcmia denticulata contained two distinct species of cestode, 

 i. e., one agreeing Avith Biehm's I), lattssimum and T. goezcij the other 

 with Cteuotcmia pectinata (Goeze, 1782 partiin, Biehm, 1881), Railliet, 

 1893. We then expressed the opinion that an error had occurred in 

 the original label of Budolphi's specimens, and that they were in real- 

 ity leporine rather than bovine cestodes. 



Baird's description 8 of T. goezei, in 1853, reads as follows: 



19. Tcenia Goezii, Baird. Head wanting. Articulations of body very short, numer- 

 ous. The inferior margin (straight. Genital orifices opposite, situated on or near 

 the lower edge of each joint, the lemniscus being projected out in form of an ele- 

 vated papilla, which curves downward. Greatest "breadth of body 6 lines, length 

 of articulations about | a line. 



This species differs from expansa and denticulata in having the posterior border or 

 edge of each joint smooth and rounded, instead of being crenulate or undulated, 

 and having the genital orifices situated on the lower edge of the joint instead of in 

 the middle.
