6. On the Brain and Muscular Anatomy of Anlacodus. By 

 Frank E. Beddard^ M.A., F.Z.S., Prosector to the 

 Society. 



[EeceiTsd May 3, 1892.] 



The visceral anatomy of this Rodent has been described in the 

 'Proceedings' of this Society^ by Mr. Garrod. The death of a 

 specimen recently deposited in the Menagerie enables me to 

 supplement that paper by a few notes upon the brain and the mus- 

 culature which were not investigated by my predecessor. 



I. Muscular Anatomy. 



The Pectoralis major may be said to be composed of four more 

 or less distinct portions ; the attachments of these were at any rate 

 separate : the first part of the complex muscle is inserted on to the 

 deltoid ridge and is 16 mm. across at the insertion; immediately 

 below this is a slip of the extensive Panniculus carnosus. Above 

 this the second part of the pectoral is inserted on to the head of the 

 humerus and for a certain distance down the shaft; the insertion 

 is only slightly narrower than that of the first part, measuring 

 15 mm.; two smaller slips are inserted just below the second part
