THE GREAT ANTEATER. 135 



form a tendinous sheath enveloping the sternoglossi, with which they are continued to 

 the sternum' :" in this description will be recognized what I have described as gular 

 fasciculi, or dismemberments of the sternoglossi and genioglossi respectively. For the 

 absence of any styloglossi, Duvernoy accounts by the remark, " that the base of the 

 tongue is much further back than the stylohyal-." But this is not the case in the 



Great Anteater. 



In the posthumous edition of Cuvier's ' Lecons d'Anatomie Comparee,' t. iv. 1836, 

 p. 558, Prof. Duvernoy intimates, that the brief notice respecting the anatomy of the 

 tongue in the Anteaters, inserted in the first edition, was an extract from a Memoir on 

 that subject, which he read to the ' Society de la Faculty de Medecine de Paris' in 1804, 

 and which was afterwards inserted entire in the ' Memoires de la Socie'tc^ d'Histoire 

 Naturelle de Strasbourg,' torn. i. 1830. 



On referring to the latter volume, I find that the interesting remarks of the venerable 

 anatomist were based upon dissections of the Myrmecophaga tamandua, Cuv., the Myrme- 

 cophaga didactyla, and the Echidna Hystrix : the Great Anteater {Myrmecophaga jubata) 

 seems not to have come under the scalpel of either Cuvier or Duvernoy. Whatever 

 discrepancy, therefore, may be found between the descriptions in the present Memoir 

 and those in the ' Strasbourg Transactions,' may be set down, either to a different inter- 

 pretation of the structures observed, or to the specific modifications of the Myrmeco- 

 phaga jubata. I have not, at least, had the opportunity of testing by actual dissection 

 the degree of concordance between the Myrmecophaga tamandua and the large species 

 which would seem to have been now anatomized for the first time.
