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

 snout to the extremity of the tail 15 inches, and from the tip 

 of the latter to the anus 8f inches. 



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

 Anteater have been the subject of description either by pen or 

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

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

 which 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 figures drawn by the latter, though from an 

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

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

 is hoped that the following notes will fill up any gaps which 

 may still exist in the knowledge to which 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 with the aponeurosis of the external oblique; while 

 dorsally it is continued into fascia covering the the intercostal 

 muscles and those of the back.

 "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 right. 



The translator, in some "Additional Notes" (p. 169), quotes from the 

 ' Penny Cyclopaedia ' (vol. ii. pp. 63-66) 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, " rarely met 

 with." 



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

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

 Paraguay y Rio de la Plata, escritos por Don Felix de Azara, en dos 

 tomos, en la imprenta de la viuda de Ibarra, Madrid." 



2. " Apuntamientos para la Historia natural de los paxaros del Paraguay 

 y Rio de la Plata, escritos por Don Felix de Azara, en tres tomos. Ma- 

 drid, 1802."

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 has, 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.
