iiculatlons, he caUecl one species the taenia with 

 long articulations f the taenia without thorns, and 

 that with thorns, the taenia with short articuld' 

 tions,(iS) 



Xrin^aejts, presuming he saw a peculiar charac- 

 ter in the position and numher of the papiUae, has 

 descrihed three species,(49) calling the first of 

 them Taenia solium osculis marginalibus solita- 

 riis,{?0) the second Taenia vulgaris oscidis latere 

 alibiis geminis,[5i) and the third Taenia lata oscu^ 

 lis lateralibus solitariis.{^2) 



Pallas^ not wishing to deviate from the charac- 

 ters of Andry, of Bonnet and of Linnaeus, has 

 adopted six species(53) of them, the two last of 

 which, according to the celebrated ^/ocA, can by no 

 means be included in the genus of the taenia. 

 Goeze having ascertained the fifth and sixth spe- 

 cies of taenia described by Pallas to be incorrect, 

 he admits only the four first,(54) announcing at 

 the same time some uncertainty as to the fourth 

 species (Taenia tanella,) which be believes to be 

 rather a variety of the flat taenia,(55) and to con- 

 stitute the third species. 



Without detracting from the merit of three great 

 naturalists, such as Linnaeus, Pallas and Goeze, 

 in reflecting on their writings, and contemplating 

 tlieir figures of the taenia, we perceive that tlie char- 

 acters they have drawn of the diversity of the spe- 

 cies, are liable to weighty objections. The broad- 

 est articulations may, in certain circumstances, con- 

 tract, shrink, and again possess a width and size
