10. Myadora Pandor^formis. Anatina Pandorieformis, Stutcli- 



bury, Zool. Journ. vol. v. p. 99 ; Tab. Supp. xliii. f. 3 and 4. 

 Conch. Iconica, Myadoi-a, pi. 1. f. 10. 



The Myadorce striata, brcvis, and Pa/idorceformis are the only spe- 

 cies of the genus at present known to have the clavicle. 



The Secretary called the attention of the Meeting to a specimen 

 of the Two-toed Sloth, Bradypus didactylus, which was now in the 

 Gardens, and requested Mr. Ball, Secretary to the Royal Zoological 

 Society of Ireland, to communicate such particulars connected with 

 the habits and manners of this curious animal as had fallen under 

 his observation. 



Mr. Ball regretted that it was out of his power to state the exact 

 locahty from which the animal had been obtained ; however, he had 

 reason to believe that it was brought from Deinerara. 



Its general food was sea-biscuit and water; of fruit it partook 

 sparingly, but he had obsen'cd it pick the young buds of the haw- 

 thorn flowers and eat them with great avidity. 



While in the Zoological Gardens at Dublin its favourite position 

 was where it was supported partly by the branch to which it clung, 

 and partly by an adjoining branch on which its back could rest. 



In lapping water, the great length to which its tongue was pro- 

 truded was very remarkable, thereby showing its affinity to the other 

 Edentata of South America.
