I ni Katalog steht : Deux especes de Tdnias rendues par la vaclie. Auf eiueiu anderu 

 Glase steht: Tenias rubanes dans la caillette d'une vaclie. Ich muss aber alles fiir 

 einerley balten, und liabe scbon vou dem Wurni eine kurze Besckreibuug gegeben 

 wie icb von dem Kabinet der Thierarzneyschule in Hannover sprach. 



Still later Eudolphi 1 in 1810 continues the parasite under the same 

 name and discusses it more in detail. His entire remarks are quoted 

 here, as they are important, being based upon the original material. 2

vissimis foraminibus marginalibus oppositis, lemuiscis dentiformibus.

Hab. in Jlwe. Camperus a bove; Havemannus, Scliolae Vet. Hannov. Director 

 meritissimiis- a vitulo (solitariani, capite destitutam); Cbabertus a vacca copiose, 

 dejectam observaveruiit, hie etiani in vaccae ventriculo quarto reperit. Specimiua 

 mea ex Mnseo Scbolae Veterinariae Altorfensis ditissimo. 



Descr. Vermes quindecim ad sedecim polliceslongi, antice duas ad quinque liueas, 

 postice frve pollicem lati; coloris albidi, vel grisei. 



Caput ^xiguuin, tetragonum, latiusculum, osculis quatuor, anticis, subcontiguis, 

 subglobosis, liorum apertuia exigua, orbiculari. Collum iiullum. Articuli aliquot 

 capiti proximl angusti, mox vero latiores, tandem latissimi et subaequales fiunt, ita 

 tamen, ut in uno alterove specimine media verinis pars paullo angustiores et simul 

 longiore^ objiciat; omnes ce.teroquiu brevissimi, ut longitudo latissimorum vix 

 liueam, Tplurimorum no dimidiam quidein excedat. Margines articuloruni postici 

 crenati sive undulati superficieni insequentium qua partem tegnnt; latcrales (aute- 

 rioribus nonnullis, rarius mediis quibusdam articulis exceptis) obtusiusculi [p. 81], 

 foramine utrinque medio, opposite, insignes, e quo denticulus acutus, leviter reflex us 

 et duriu^culus (lemniscus) exseritur. Substantia mollis, plus minus crassiuscula, ut 

 crassities iuterdum lineam adaequet. Ova in substantia media cumulata, ovariis 

 regularibus mibi lion visis. 



Obs. 1. Carlisle in figuris citatis canales articulorum laterales longitudinem versus 

 decurrentes et ovaria in racemum brevisainium et latissimum digesta, babet ; baec 

 omnia lie in tenuioribus quidein speciminibus vidi, vel sectione detegere potui. 

 Denticuli validi liorunKiue foramina ab eodem minus bene sistuntur. 



Obs. 2. Chabertus in opere Bibl. n. 19.9. 3 indicate Taeniam hancce cum reliquorum 

 mammalmm Taeniis, sub nomine Tnia ruban6, perperam conjunxit, in Musei Alfor- 

 tensis autem catalogo duas in species (T<5nia rubane" et Tenia lanceole) praeter ullam 

 necessitatem divisit, nani specimina niiuora quam reliqua ad formaui lanceolatana 

 magis accedere nil refert. 



Obs. 3. A specie praecedente notis in obs. 2. ad eandem indicatis abunde differt 

 quibus autem Taenia caprae n. 84. dicta distinguenda sit, hujus capite nou viso 

 determinare non ausini; pars antica tanaeji quam in denticulata tenuior, licet quaiu 

 in praecdente latior, videtur. 



That the citations from Camper, Carlisle, and Gmelin must be 

 rejected from the bibliography of this species follows from the data 

 given on page 177.

2 The original description of 1804 is evidently based upon the Alfort material and 

 not upon tlie specimen seen at Hanover. Chabert's specimens must therefore be 

 taken as types.
