a female, fairly developed, and measured from tlie tip of tlie 

 snout to tlie extremity of the tail 15 incites, and from the tip 

 of the latter to the anus 8| inches. 



This is not the tirst time that the muscles of this species of 

 Anteater have been the subject of descrij)tion either by pen or 

 pencil, seeing that Meckel, at the beginning of the present 

 century, published a paper on its anatomy in the ' Archiv ' 

 Avhich bear his name*, and Cuvier devoted two plates of his 

 splendid Atlas to the illustration of its myology f. 



Since, however, the descriptions of the former author are 

 somewhat lacking in completeness and fulness in certain points, 

 and since the tigures drawn by the latter, though from an 

 artistic point of view faultless, are, for the stern needs of the 

 dissector, "un faiblc secours," as remarked by M. Pouchet, it 

 is hoped that the following notes will till uji any gaps which 

 may still exist in the knowledge to Avhicli these great anato- 

 mists have so largely contributed J. 



Panniculus carnosus. This muscle is most developed in the 

 abdominal region and flanks. The "portion ventrale " of 

 Cuvier is, on either side of the middle line of the abdomen, 

 fused wdth the aponeurosis of the external oblique ; while 

 dorsally it is continued into fascia covering the the intercostal 

 muscles and those of the back. 



ralists, and thus concludes, after the fashion of a counsel on a losing side : — 

 "Finally, I leave it to time to prove or disprove my conjecture.'' Time 

 has disproved his conjecture ; and Buffon, for once in a way, is rig-ht. 



The translator, in some "Additional Notes" (p. 1G9), quotes from the 

 * Penny Cyclopaedia ' (vol. ii. pp. G3-6G) a description of the habits of the 

 Anteater in question, which was taken from Yon Sack's ' Narrative of a 

 Voyage to Surinam ' — a work, as Mr. Hunter truly observes, '' rarelv met 

 with.'^ 



I extract from tlie preface to Mr. Hunter's translation the Spanish titles 

 of Azara's works, which were published in five octavo volumes : —

 Paraguay y Kio de la Plata, escritos por Don Felix de Azara, en doa 

 tomos, en la impronta de la viuda de Ibarra, Madrid."'

X I should here state that Prof. Humphry had completed the dissection 

 of a Two-toed Anteater before my labours had begun ; but, as he intends 

 reserving his notes for the next number of the ' .Journal of Anatomy and 

 Physiology,' he ha.o,with great kindness and liberality, made no objection 

 to the prior publication of observations which are, in point of time, of later 

 date than his own.
